Quick answer

Key takeaways

Tolerance drives the machine, not the price listBelow ±0.005 mm, ask which machine holds it and how it is measured.

Quote speed tells you about capacityA DFM note within 12 hours usually means the shop has open spindle time.

No MOQ matters for prototypesOne part to 10,000+ runs, with the same inspection route.

Certificates must match your industryISO 9001 alone will not pass an automotive or medical audit.

Watch the quoting basisCompare cycle time, material, finishing, and inspection as separate lines.

Judgment table

How to read a supplier's claim against your part

Use this to decide what to ask before releasing a drawing.

What to check	Weak answer	Strong answer	Why it matters
Tolerance	"We hold ±0.01 mm"	Named machine and CMM report	The process must match the callout
Lead time	"Typically 2 weeks"	3–5 days after drawing release	Vague dates hide queue time
MOQ	"Minimum 100 pcs"	One prototype to 10,000+	Prototype cost decides the program
Certifications	"We are ISO certified"	ISO 9001, IATF 16949, ISO 13485	Each industry audits differently
Quoting basis	One lump sum	Material, cycle, finish, inspection	You can see where cost sits
DFM feedback	Silent quote	Written DFM within 12 hours	Fixes come before the tool cuts

The verdict: check the process, not the brochure

If a supplier can name the machine, the setup, and the measurement method for your tightest feature, the rest of the quote is worth reading. If not, keep looking.

Check 1

Tolerance: match the claim to the machine and the measurement

Tolerance is the first number engineers compare, and the easiest one to misread. A shop can quote ±0.005 mm and still fail your part if the feature is 300 mm from the fixture or sits on a thin wall. Ask which machine will run the job and where the datums sit in the setup. On a 5-axis center with a Ø400 mm rotary table, a bore and its mating face can be cut in one setup, which removes the stacked error you get from two fixtures.

Measurement matters as much as cutting. A tolerance of ±0.005 mm is only useful if the shop can measure it. Touch probes and CMM reports should be part of the route for tight features, not an extra you buy later. We inspect 100% of parts before shipment, with raw material checks, in-process monitoring, and a final inspection report on request.

Some parts should not be quoted at ±0.005 mm. Deep pockets in soft aluminium, thin plastic walls under 0.8 mm, and long unsupported bores will move after clamping or from heat. In those cases we say so in the DFM note and propose a realistic tolerance or a design change. That conversation is cheaper than a rejected lot.

1
Ask for the setup planOne setup beats three when the tolerance is tight.
2
Ask how the feature is measuredIf there is no measurement method, the tolerance is a guess.
3
Expect a counter-proposalA good shop pushes back when the drawing fights the process.

Lead time: separate machining days from queue days

Lead time quotes mix three things: queue, machining, and finishing. A shop can machine your part in two days and still ship in three weeks because the anodizing line is full. Ask for the split. We quote and return a free DFM analysis within 12 hours, can start production within 24 hours, and ship parts in 3–5 days. Those numbers assume the drawing is frozen and the material is in stock.

Material is the quiet variable. 6061-T6 and 304 stainless are usually on the shelf. Inconel, Ti-6Al-4V, and 17-4PH often are not, and the mill lead time lands on your schedule. If your program is on a deadline, ask the shop to confirm billet availability before you approve the PO rather than after.

Finishing adds its own clock. Anodizing, electroless nickel, and powder coating are batch processes. A small lot may wait for a full rack. If the finish is cosmetic, ask what the batch schedule looks like before you promise a date to your own customer.

1
Get the queue numberMachining days are not the same as days to ship.
2
Confirm material stockExotic alloys can add weeks before the first cut.
3

MOQ, certifications, and industries: the audit trail

Minimum order quantity decides whether a supplier fits your program stage. A shop with a 100-piece minimum is a poor fit for a design you are still testing. We run no minimum order quantity, from one prototype to 10,000+ part runs, using the same machines and inspection route. That keeps prototype data comparable to production data.

Certifications are not interchangeable. ISO 9001:2015 covers quality management. IATF 16949:2016 is what automotive and EV programs expect. ISO 13485:2016 applies to medical devices. ISO 27001:2022 covers information security, which matters when your drawings and CAD files leave your network. If your audit needs one of these, ask for the certificate scope, not just the logo.

Industry experience shows up in details. Aerospace work cares about traceability and material certs. Automotive cares about PPAP-style documentation and process control. Medical cares about clean handling and change control. Ask what the shop normally runs. A supplier who machines your part type every week will quote it faster and machine it better.

1
No MOQ keeps prototypes honestSame process, one part or ten thousand.
2
Match the certificate to the auditISO 9001 is a baseline, not a pass for every industry.

Ask about file securityISO 27001 and an NDA protect your drawings.

Quoting: what a real price breakdown looks like

A single lump-sum price hides the cost drivers. Ask for four lines: material, machining cycle, finishing, and inspection. Then you can see whether the quote is high because of the alloy, the tolerance, or the surface finish. A quote with no breakdown cannot be compared against a second supplier in any meaningful way.

Watch for missing scope. Setup, fixturing, and programming are real costs, especially on low-volume parts. If a quote looks unusually low, it may exclude the fixture or assume a looser tolerance than the drawing states. That difference shows up later as a change order.

Beware of a quote that arrives without questions. A shop that never asks about datums, critical features, or finish probably did not read the drawing closely. We send a written DFM analysis with the quote so the assumptions are on the table before you approve anything. Uploads stay secure and confidential, and we sign an NDA on request.

Capacity and materials: can the shop actually run your part

Capacity is more than a machine count. Our three wholly-owned plants cover 7,600 m² with 127 high-precision CNC machines, including 16 simultaneous 5-axis machining centers, 12 four-axis mills, 27 three-axis machines, and 16 mill-turn centers. Maximum processing size reaches 4,000 mm, with travels from 500 × 310 × 200 mm up to 4,000 × 400 × 150 mm.

Materials tell you whether the shop machines your part family. We cut aluminium 6061, 7075, and 6082; stainless 303, 304, 316L, and 17-4PH; steel 1018, 4140, and 4340; copper and brass; titanium TA2 and TC4; Inconel; magnesium; and plastics from ABS and POM to PEEK and carbon fibre. Each family behaves differently at the tool tip, and setup choices change with it.

Finishing sits in the same building group. Anodizing in clear, colour, hardcoat, and conductive grades, electroless nickel, zinc, silver and gold plating, powder coating, black oxide, bead blasting, polishing, and laser marking all run through controlled vendors. When finishing is in scope, the supplier owns the final dimension and the cosmetic result together.

1
Check the travel envelopeA large part on a small machine loses accuracy.
2
Ask about your alloyTitanium and Inconel need different speeds and fixtures.
3
Keep finishing in scopeOne owner for dimension and cosmetics.

Workflow

Step by step: qualifying a supplier in one week

Run these in order. Each step produces a document you can compare.

1
Send the drawing with callouts highlightedMark critical dimensions, datums, and finish requirements. Include the material spec and any industry standard the part must meet.
2
Request a quote with DFM notesAsk for the four-line breakdown and a written DFM analysis. A 12-hour turnaround is a reasonable benchmark for a simple part.
3
Confirm tolerance and measurement methodAsk which machine runs the tight feature and how it is verified. Expect a CMM report on request for anything below ±0.01 mm.
4
Order one prototype part firstNo MOQ means you can test fit and finish before committing to a run. Check the surface finish against Ra 0.8–1.6 μm or your stated callout.
5
Review the inspection reportCompare measured values to the drawing. Look for the raw material cert and any in-process records the shop provides.
6
Scale to the production runIf the prototype passes, move to the full quantity. Keep the same process route so the data stays comparable.

FAQs

Questions buyers ask before a PO

What tolerance can a supplier realistically hold on a 200 mm part?

It depends on the feature and the setup. On a rigid part cut in one setup, ±0.005 mm is achievable on critical bores and faces. Long parts, thin walls, and features far from the datum will move.

Ask for the setup plan and the measurement method. If the shop cannot name both, treat the tolerance as a target rather than a guarantee.

How fast can parts ship after I approve the quote?

We can start production within 24 hours and ship parts in 3–5 days, assuming the drawing is frozen and the material is in stock.

Exotic alloys and batch finishing processes can add time. Confirm both before you commit to a customer date.

Do I have to order a minimum quantity?

No. We run no minimum order quantity, from one prototype to 10,000+ part runs.

The prototype and the production run follow the same machine and inspection route, so the data you validate carries over.

Which certifications should I ask for?

Start with ISO 9001:2015 as the baseline. Add IATF 16949:2016 for automotive and EV work, ISO 13485:2016 for medical devices, and ISO 27001:2022 if file security is part of your audit.

Ask for the certificate scope. A logo on a website does not tell you which processes are covered.

How do I compare two quotes that look different?

Break both into material, machining cycle, finishing, and inspection. Then compare scope: setup, fixturing, programming, and whether inspection reports are included.

A low quote often excludes the fixture or assumes a looser tolerance. That gap becomes a change order later.

Can you sign an NDA before I share CAD files?

Yes. Uploads are secure and confidential, and we sign an NDA on request.

If your program requires documented information security, ISO 27001:2022 covers how files are handled internally.
