Quick Answer

Buying the right blown film machine starts with defining your film product — not the machine specification. The ten factors that determine whether your machine produces saleable film at a profit, in priority order, are: (1) your film product and application requirements, (2) layer configuration (mono, ABA, or ABC), (3) die head diameter and quality, (4) cooling system (air ring type and IBC), (5) extruder and screw configuration, (6) automation and control level, (7) output rate vs actual production demand, (8) winder and haul-off type, (9) total cost of ownership — not purchase price alone, and (10) manufacturer capability and after-sales support. Based on Mingyang's experience commissioning machines in 40+ countries, the single most expensive mistake buyers make is starting with a budget number and working backward — instead of starting with the film product and working forward to the right configuration.

A buyer in Accra called me three months after he had already bought a machine. He had found a mono-layer line at what looked like an unbeatable price — $26,000 delivered. Six weeks after installation, he discovered that the die head could not hold gap uniformity. The 600 mm die he needed for his film width was actually a 500 mm die with an undersized spiral mandrel, limiting his blow-up ratio and producing film with visible thickness bands. The supplier's response: "You ordered the economy model. What did you expect?"

He spent another $52,000 on a properly configured ABA machine six months later. The $26,000 "bargain" became a $78,000 lesson in buying a machine before understanding what he was buying. In eight years of selling blown film machines, I have seen every variation of this mistake. This guide walks through the ten factors in the order you should consider them — starting with your product, ending with the manufacturer — so that you buy the right machine once.

Factor 1 — Start With Your Film Product, Not the Machine

The most expensive machine is not the one with the highest price tag. It is the one that cannot make the film your customer will pay for. Before you look at a single specification sheet, define these five things:

  • Film type and application. What are you selling? LDPE shrink film for food packaging? HDPE garbage bags? Agricultural cover film? Barrier film with nylon or EVOH? Each application has different requirements for thickness tolerance, optical properties, mechanical strength, and seal performance — and each requirement drives a different machine configuration.

  • Film width range. What is the minimum and maximum flat width your customers order? The die diameter determines the maximum width at a given blow-up ratio. A 600 mm die at BUR 3:1 produces roughly 2,800 mm flat width. If your widest order is 3,500 mm, you need at least an 800 mm die.

  • Film thickness range. What micron range do you produce? Film below 50 microns benefits disproportionately from IBC and dual-lip air ring cooling. Film above 100 microns can often be produced on simpler cooling configurations. If you produce across a wide range — say 25 to 120 microns — the machine must handle both extremes without excessive changeover time or scrap.

  • Raw materials. What polymers and what percentages? 100% virgin LDPE is straightforward. 30% recycled PE in the core layer requires a barrier screw with a mixing section, gravimetric dosing, and — ideally — an ABA configuration to bury the recycled content in the core where it does not affect surface quality or seal strength.

  • Monthly output requirement. How many tons per month do you need to produce — actual demand, not aspirational? A machine capable of 300 kg/h running 24/7 produces roughly 180 tons per month. If your actual demand is 60 tons, you are paying for capacity you will never use — and a smaller machine would have paid back faster. If your demand is 150 tons and you buy a machine capable of 80 tons, you will be outsourcing within six months.

I tell every customer: the machine specification is the last thing you write, not the first. The product definition is the first thing. If a supplier starts talking about extruder diameter before they have asked what film you make, they are selling you their machine, not your solution.

Factor 2 — Choose the Right Layer Configuration

This is the single most expensive decision you will make, and the one that is hardest to change later. You cannot upgrade a mono-layer machine to ABA without replacing the die head, adding extruders, and re-engineering the entire line — effectively buying a new machine.

Configuration

Best For

Material Flexibility

Typical Price (FOB)

When It Is the Right Choice

Mono-Layer

Garbage bags, construction film, basic shrink film, agricultural film

Single material only. No recycled content hiding.

$18,000–$70,000

Single product, single material, budget-constrained, film >80µ, annual output <150 tons

ABA Co-Extrusion

Packaging film, shrink film, shopping bags, lamination film

Two materials. Recycled or filled core layer with virgin skins.

$55,000–$180,000

Most packaging converters. Want recycled content capability. Need good surface quality + cost control.

ABC Co-Extrusion

Barrier film, high-clarity packaging, multi-functional film

Three different materials. Barrier layer (nylon/EVOH), structural layer, sealant layer.

$90,000–$350,000+

Need three genuinely different materials. Barrier film. High-value niche applications.

I sell relatively few mono-layer machines these days — not because they do not work, but because most packaging converters discover within two years that they need recycled content capability or want to offer a premium multi-layer product. An ABA machine costs 50–80% more upfront than a comparable mono-layer line, but the ability to run 30–50% recycled PE in the core layer saves $30,000–$60,000 per year in raw material at 200 tons annual output. The payback on the price premium is typically 12–18 months — after which the ABA machine is cheaper to own.

Do not pay for ABC if ABA will do the job. If you are running LDPE skins with a recycled or filled core, an ABA configuration does exactly what you need for roughly 35–40% less than an ABC machine with equivalent die diameter. ABC is the right choice when you need three genuinely different materials with different processing temperatures and viscosities — a nylon barrier layer, for example, which requires a dedicated extruder with corrosion-resistant screw and barrel materials.

Factor 3 — Die Head Diameter and Quality

The die head determines your maximum film width, your minimum thickness variation, and — to a large degree — your machine's resale value. It is the single most expensive component and the hardest to repair or replace.

Diameter. Die diameter × blow-up ratio × 1.57 = flat width. For LDPE at a typical BUR of 2.5–3.5:1, a 600 mm die produces film roughly 2,400–3,300 mm flat width. For HDPE at a typical BUR of 3–4:1, the same die produces 2,800–3,800 mm. Size the die for your widest regular order — not your average order, and not an aspirational width you hope to sell someday. An oversized die running at low output produces poor melt distribution because the polymer residence time in the spiral channels is too long. An undersized die limits your product range from day one.

Quality. The die gap tolerance around the circumference should be within ±0.025 mm. This requires CNC machining and a manufacturer that verifies every die on a coordinate measuring machine before assembly. Ask the supplier: do you machine your own dies, or buy them from a third party? Can you provide the CMM report for the die on my machine? A supplier who machines dies in-house and provides tolerance data is a fundamentally different tier from a supplier who buys dies from an unknown source and cannot provide a measurement report.

Spiral mandrel design. The spiral channels inside the die distribute the melt evenly around the circumference. The number of spiral channels, the channel depth, and the channel pitch all affect melt distribution quality and are specific to the polymer type and output range. A die designed for LDPE does not distribute HDPE optimally — the viscosity curves are different. If you plan to run both LDPE and HDPE, tell the supplier before the die is designed so the spiral geometry can be optimized for the broader viscosity range.

Factor 4 — Cooling System: Air Ring and IBC

Cooling determines how fast you can run and how consistent your film thickness will be. The cooling system has two parts: the external air ring (cooling the outside of the bubble) and the optional Internal Bubble Cooling system (cooling the inside).

Single-lip vs dual-lip air ring. A single-lip air ring blows one stream of air onto the bubble. If that stream is not perfectly uniform around the circumference — and it never is — the resulting cooling asymmetry creates thickness bands. A dual-lip air ring splits the airflow into two independently adjustable streams: the lower lip cools the melt immediately as it exits the die, the upper lip stabilizes the bubble and controls frost line height. The dual-lip design reduces sensitivity to ambient air currents and typically improves thickness variation by 2–3 percentage points on its own. The cost difference is $3,000–$6,000. For film below 80 microns, the dual-lip air ring is not optional — it is the minimum acceptable cooling configuration.

IBC — when it pays and when it does not. Internal Bubble Cooling adds $8,000–$18,000 and delivers three things: 20–40% more total cooling capacity (enabling higher output), automatic bubble diameter control via ultrasonic sensors (stabilizing the frost line), and measurably better thickness consistency. On a Mingyang ABA-1200 line in Nairobi, adding IBC reduced thickness variation from ±11% to ±4.5% before any other changes. Payback from reduced scrap and increased output: 10–16 months for a line producing 200+ tons per year of film below 80 microns. IBC is not justified for thick-gauge film above 100–120 microns where cooling is not the output bottleneck, or for very low-volume operations producing under 80 tons per year where the scrap savings take too long to recover the IBC investment.

Factor 5 — Extruder and Screw Configuration

The extruder does one job: deliver homogeneous, thermally stable melt to the die at a consistent rate. Three decisions matter:

Extruder diameter. The screw diameter determines maximum throughput. A 55 mm extruder running LDPE delivers roughly 70–110 kg/h. A 65 mm delivers 100–160 kg/h. A 75 mm delivers 140–220 kg/h. Size the extruder for your target output at a comfortable screw speed — typically 80–100 RPM maximum for LDPE, 70–90 RPM for HDPE. Running at the top of the RPM range to hit your output target means the extruder is undersized, and any fluctuation in feed rate or material bulk density will show up as output variation — and therefore thickness variation.

Screw design. A standard single-flight screw works for 100% virgin material with consistent MFI. A barrier screw with a mixing section — Maddock or pineapple mixer at the metering zone end — is necessary for recycled content, blends, or materials with wider MFI variation because it ensures all polymer reaches the target temperature and viscosity before entering the die. The cost difference is $2,000–$4,000 per screw. I specify barrier screws as standard on every Mingyang machine destined for a customer who plans to run any recycled content — the mixing section pays for itself in reduced scrap within the first year.

L/D ratio. A 28:1 L/D is standard for most blown film applications and provides adequate residence time for LDPE and LLDPE. A 30:1 or 32:1 L/D provides longer residence time — beneficial for HDPE which requires more energy input to reach processing temperature, and for recycled materials which benefit from longer homogenization in the barrel. The longer barrel costs more and takes more floor space, but for HDPE-dominant production, a 30:1 L/D extruder will produce more consistent melt quality than a 28:1.

Factor 6 — Automation and Control Level

Automation reduces dependence on operator skill — and operator skill is the variable most factories cannot control across shifts. The question is not "should I automate" but "which automation pays back for my operation."

Automation Option

Cost (Approx.)

What It Solves

When Justified

PLC + touchscreen

$2,000–$5,000

Recipe storage, alarm logging, single-screen control

Essentially always. This is baseline, not optional.

Gravimetric dosing

$3,000–$8,000 per extruder

Blend ratio drift, inconsistent recycled content percentage

Any recycled content. Any blend of materials.

IBC with auto bubble control

$8,000–$18,000

Bubble instability, frost line fluctuation, cooling-limited output

Film <80µ, production >150 t/yr, tight thickness tolerance

Automatic gauge control

$15,000–$30,000

Real-time closed-loop thickness correction

24/7 operation, demanding customers who measure, >300 t/yr

Corona treater

$5,000–$12,000

Surface energy for printing/lamination

Only if film will be printed or laminated.

Do not pay for automation you will not use. A small factory running one shift with a skilled operator on the same machine every day does not need AGC — the operator's experience plus a well-maintained die and dual-lip air ring can hold ±6–8% thickness variation, which is adequate for many commodity film applications. Invest the $20,000 you save into a gravimetric dosing system and operator training instead. Conversely, if you run 24/7 with three rotating operators, the consistency that AGC provides across shifts is worth its cost — because the variation between operators is usually larger than the variation within one operator's shift.

Factor 7 — Output Rate vs Actual Production Demand

Output rate is the most over-specified and least honestly reported number in blown film machine sales. Suppliers quote maximum output under ideal conditions: a specific film width, thickness, material grade, and melt temperature that may not match your daily production reality. I have measured actual output on commissioned machines that was 15–25% below the supplier's quoted maximum — not because the machine was defective, but because the quoted number assumed a thinner film, a narrower width, and a higher melt temperature than the customer's product required.

To get a realistic output estimate for your production:

  1. Ask for output data at your specific film thickness and width. Not "maximum output" — output at your product. A machine quoted at 200 kg/h maximum may produce 140 kg/h at your actual film specification.

  2. Calculate actual required output. Monthly tons × 1,000 ÷ operating days ÷ operating hours per day = required kg/h. Add 15–20% headroom for growth and downtime. If you need 100 kg/h to meet orders, spec a machine capable of 120–130 kg/h sustained — not 100 kg/h peak.

  3. Size for sustained output, not peak. A machine running at 90% of its maximum screw speed for 20 hours a day will have a longer service life, lower scrap, and fewer unplanned stops than a machine running at 100% for the same duration.

A machine that is too large for your actual demand wastes capital and runs inefficiently at low output. A machine that is too small forces you into outsourcing, overtime, or turning away orders. The right size is the one that matches your largest regular customer's demand plus reasonable growth — not your aspirational five-year plan.

Factor 8 — Winder and Haul-Off Type

The winder is where the customer sees your quality — or does not. A poorly wound roll with soft edges, telescoping layers, or inconsistent tension produces waste at the customer's machine, and they will blame the film, not the winder.

Winder types:

  • Friction winder ($3,000–$6,000): The winding shaft is driven by surface contact with a friction roller. Adequate for narrow rolls, small diameters, and moderate line speeds. Inconsistent tension control at higher speeds or with larger roll diameters.

  • Center winder with tension control ($8,000–$18,000): The winding shaft is driven directly by a motor with closed-loop tension feedback. Produces consistent roll hardness from core to outer layer at higher speeds. The minimum I recommend for film sold to automatic packaging lines.

  • Center-surface gap winder ($12,000–$25,000): Combines center drive with a surface-lay-on roller that maintains a controlled gap to the winding roll. The reference standard for high-speed, large-diameter rolls. Gap control prevents air entrapment between layers and ensures flat roll profile.

Haul-off: The nip roller assembly that pulls the bubble upward. For lines with a fixed die (no rotation), an oscillating haul-off ($8,000–$15,000 premium) distributes thickness variation across the roll width and prevents hard bands — visible ridges in the finished roll. For lines with a rotating die, the haul-off can be fixed. For dies above 800 mm, I recommend oscillating haul-off over rotating die — rotating a large, heavy die assembly introduces more maintenance complexity than oscillating the relatively lighter nip assembly.

Factor 9 — Total Cost of Ownership, Not Purchase Price

Over a 250-ton-per-year blown film line's 8-year service life, the machine purchase price represents approximately 3–4% of the total cost. The raw material is the dominant cost at roughly 85–88%. Electricity is 5–7%. Scrap — depending on the machine's thickness control capability — is 3–10%. Maintenance and spare parts are 1–2%.

This means a machine that costs $20,000 more to buy but reduces scrap by 3 percentage points saves roughly $66,000 in raw material over 8 years — more than three times the price difference. A machine that enables 30% recycled content in the core layer saves roughly $40,000–$50,000 per year in raw material at 250 tons annual output. The purchase price is a rounding error compared to the material savings from the right configuration.

When comparing quotations, build a three-year operating cost model for each option that includes: raw material consumption (tons × price per ton, including scrap), electricity (kW × hours × rate), estimated maintenance and spares, and operator labor. Add the machine purchase price. The option with the lowest three-year total cost is the right one — and it is rarely the one with the lowest purchase price.

Factor 10 — Manufacturer Capability and After-Sales Support

The manufacturer's engineering depth and support infrastructure determine whether your machine arrives on time, runs correctly from day one, and keeps running for years. Here is what separates a manufacturer from a trading company:

In-house die manufacturing. If the supplier does not machine their own dies, they cannot control the single most critical quality variable on the machine. Ask directly: "Do you machine your own die heads? Can I see the machining area and the CMM report for a recent die?" A manufacturer who says yes and shows you the data is a legitimate machine builder. A manufacturer who hesitates or deflects is likely buying dies from a third party — and the die is the component you cannot afford to be of unknown origin.

Factory acceptance test. Every machine should run with the customer's actual raw materials before shipping. During the FAT, measure thickness variation at three output rates, verify output against the specification, and check energy consumption. If the supplier does not offer a FAT or cannot accommodate your raw materials, treat this as a warning.

Spare parts availability. Ask for a recommended spare parts list with individual pricing and lead times. A manufacturer who stocks 2,000+ SKUs with 48-hour dispatch on critical items is operating at a different level of customer commitment than one who orders spares from suppliers only when a customer needs them.

Commissioning and training. On-site commissioning by a factory-trained technician should be included in the machine price — confirm this. The commissioning process should include die gap verification, air ring tuning, frost line height setup, bubble diameter sensor calibration (if IBC), and operator training on all control functions. A 5–7 day on-site process is standard. A half-day setup is not commissioning; it is a delivery.

Reference customers. Ask for contact information for customers who bought a similar machine configuration 12–24 months ago — long enough to have real production experience. Call them. Ask about machine reliability, thickness consistency, spare parts delivery time, and whether the manufacturer responded when something went wrong. A manufacturer who cannot provide references for a machine similar to what you are buying is either inexperienced with that configuration or unwilling to let you talk to their customers. Neither is acceptable.

Real Case — How a Buyer in Lagos Avoided a $41,000 Mistake

In 2025, a converter in Lagos, Nigeria, was comparing two suppliers for an ABA blown film machine to produce 30-micron LDPE shrink film. Both quotations were for an ABA configuration with a 1000 mm die and IBC. Supplier A quoted $72,000. Supplier B — Mingyang — quoted $94,000. The price difference was $22,000 for what appeared to be the same specification.

The buyer flew to China and visited both factories — a decision that saved him far more than the airfare. At Supplier A's factory, the die heads were machined by a subcontractor in another province. The factory floor had no CMM. The FAT area was a corner of the assembly shop with no dedicated measurement equipment. At Mingyang's factory, dies were machined in-house on CNC centers with CMM verification data for every die. The FAT area was a dedicated bay with thickness measurement, energy metering, and a control room for recording data.

The buyer ordered from Mingyang. Twelve months into production, the machine runs at ±3.8% thickness variation, 3.1% scrap rate, and 185 kg/h sustained output on 30-micron LDPE. A converter in the same industrial area who bought the $72,000 machine from Supplier A reported thickness variation of ±9%, scrap at 8.5%, and three unplanned stoppages in the first year due to die head issues that required the manufacturer to fly in a technician — at the customer's expense.

The $22,000 price difference was recovered in 14 months through lower scrap and higher output. The real cost of the cheaper machine — counting lost material, lost production time, and customer returns — was approximately $41,000 higher in the first year alone.

Why Buyers Choose Mingyang for Blown Film Machines

Selecting a blown film machine supplier is a decision you will live with for 8–10 years. Here is what Mingyang brings:

  • 20+ years manufacturing blown film and bag making equipment at our production base in Jiangyin, Jiangsu, China. We design, machine, assemble, and test in-house — die heads, screws, barrels, air rings, IBC mandrels, and control systems.

  • CE and ISO 9001 certified. Every die head is machined to ±0.015 mm tolerance and verified on a CMM before assembly. We provide the measurement report with the machine documentation.

  • In-house die manufacturing. Our CNC machining center produces die heads from 400 mm to 2000 mm diameter. We do not outsource dies — the component that most directly determines film quality stays under our control from raw forging to finished assembly.

  • Factory acceptance test with your raw materials. Every machine runs a full-day FAT before shipping. We measure thickness variation at three output rates, verify output and energy consumption, and provide the complete data to you. You are welcome to attend the FAT in person or receive the data remotely.

  • 40+ countries. Mingyang machines are running across Southeast Asia, Africa, the Middle East, and South America. Our technical team has experience with diverse voltage standards, climate conditions, and raw material supply chains.

  • 2,000+ spare parts SKUs in stock. 48-hour dispatch on critical items. We stock finished die heads, screws, barrels, air rings, IBC components, and drives — not just consumables.

  • On-site commissioning and training included. 5–7 working days of technician time covering installation, die gap verification, cooling system tuning, control system setup, and operator training. The machine produces saleable film before handover.

Pre-Purchase Verification Checklist — Questions for Any Supplier

  1. Do you machine your own die heads? If yes, ask to see the machining area and a recent CMM report. If no, who supplies your dies, and what is their tolerance specification?

  2. Can I attend the FAT with my raw materials? A supplier who resists an in-person or remote FAT attendance is not confident in their machine's performance — or has something to hide.

  3. What thickness variation do you guarantee at my specific film width, thickness, and material? "±5%" without asking your product is not a guarantee — it is a marketing claim. Push for the number under your conditions.

  4. Provide a component-level price breakdown. Die head, each extruder, cooling system, winder, controls, options, and installation. A single total price tells you nothing about where the money is going.

  5. What is the recommended spare parts list with individual pricing? If the supplier cannot produce this within a few days, they do not have a structured spare parts operation.

  6. Provide contact information for two reference customers who bought a similar configuration 12–24 months ago. Call them. Ask about reliability, thickness consistency, spare parts delivery, and after-sales responsiveness.

  7. What is included in the warranty and for how long? 12 months from shipment or 18 months from delivery is standard for critical components (gearbox, screw, barrel, die head, motors). Parts and labor should both be covered.

  8. Is on-site commissioning and training included? How many days? Who performs it — a factory-trained technician or a local agent?

Frequently Asked Questions

Should I buy a mono-layer or ABA machine for my first blown film line?

If you are starting a blown film operation and your budget is firmly capped below $40,000, a mono-layer machine with a dual-lip air ring is the practical entry point. If your budget allows $60,000–$90,000, an ABA machine with IBC will give you recycled content capability and better thickness control from day one — capabilities that are difficult and expensive to add later. Based on inquiries to Mingyang over the past three years, roughly 70% of first-time buyers who start with a mono-layer machine contact us about upgrading to ABA within 24 months. The reason is always the same: their customers ask for film with recycled content (to meet sustainability requirements or reduce cost), and the mono-layer machine cannot deliver it without sacrificing surface quality.

What die diameter do I need for my film width?

Die diameter × blow-up ratio × 1.57 = flat width. For LDPE at BUR 3:1: a 500 mm die = 2,355 mm flat width; 600 mm = 2,826 mm; 800 mm = 3,768 mm; 1000 mm = 4,710 mm; 1200 mm = 5,652 mm. Size for your widest regular order, not your average. An undersized die limits your product range; an oversized die running at low output produces poor melt distribution. If your product range spans a wide width range, a mid-sized die with adjustable BUR is more practical than trying to cover everything with one fixed configuration.

How do I verify a supplier's die head quality before ordering?

Three things: (1) Ask whether dies are machined in-house. (2) Ask for the manufactured tolerance specification — ±0.025 mm or better is achievable, ±0.015 mm is reference standard. (3) Ask how they verify — a CMM report for each die is the industry benchmark. During a factory visit, look at the machining area. CNC machining centers from reputable brands (DMG Mori, Mazak, Haas) are a positive signal. A die head being hand-finished with a file is not. Ask to see the CMM report for a die currently in assembly — not a sample report, the actual report for a die that will ship to a customer. A manufacturer who cannot produce this on request is not measuring their dies, or is not willing to show you the results.

How much should I budget for installation and commissioning beyond the machine price?

For most Chinese-manufactured blown film machines, on-site installation, commissioning, and operator training are included in the machine price — confirm this explicitly in the quotation. Beyond the machine price, budget for: sea freight ($3,000–$12,000 depending on destination), import duties (0–15% depending on country and trade agreements), local handling and inland transport ($500–$2,000), and factory-side preparation (foundation, power connection, cooling water if required, compressed air — typically $2,000–$5,000). Total beyond-machine costs typically add 15–30% to the FOB machine price. Get an independent freight forwarder quotation rather than relying solely on the supplier's shipping estimate.

What is the most common mistake first-time blown film machine buyers make?

Buying based on purchase price alone. A $30,000 machine that produces 10% scrap costs more to own over three years than a $70,000 machine producing 3% scrap — the raw material wasted through scrap, which the buyer never calculates, exceeds the price difference within 18–24 months. The second most common mistake: buying a machine without attending a factory acceptance test or verifying the supplier's die manufacturing capability. The die head is the heart of the machine, and a die of unknown manufacturing origin is the single biggest quality risk. The third: not sizing the machine for the actual film product. A machine configured for 100-micron HDPE construction film will not produce 25-micron LDPE shrink film to packaging specifications.

How long does it take from order to production?

Standard manufacturing lead time for a configured blown film machine from Mingyang is 45–60 days from order confirmation to ex-works shipment. Larger lines (die above 1200 mm) or highly customized configurations may require 60–90 days. Sea freight to most destinations: 15–45 days. Customs clearance and inland transport: 3–10 days. On-site installation and commissioning: 5–7 working days. Total timeline from order to commercial production: approximately 10–16 weeks for most destinations. Plan your order timing accordingly — ordering a machine when your existing line is already at capacity means weeks of lost production or outsourcing costs.

Is it worth visiting the factory before ordering?

Yes — for any machine above $50,000, the cost of a factory visit ($2,000–$4,000 including flights and accommodation) is small relative to the cost of buying the wrong machine. During the visit: watch a machine run with film similar to yours, measure the thickness variation yourself (ask to see the gauge display during the run), inspect the die machining area and ask to see a CMM report, and talk to the technicians who will build your machine — not just the sales manager. A factory that is clean, organized, and has quality control processes visible on the floor is a fundamentally different operation from one that is not. Take photos of the machining area, the assembly floor, and the FAT setup. If the visit raises concerns you would not have caught from the quotation alone, it paid for itself many times over.
