What a manufacturer actually delivers

A real tablet press builder owns five things: design (not a copied layout), machining of the turret and cam, assembly and alignment, validation documentation (FAT/SAT/IQ/OQ), and spare-parts continuity. A trading company owns none of these and resells someone else's press with a markup and a warranty it cannot honour.

OEM vs ODM vs trading company

• OEM: builds to its own design, controls the turret tolerance — preferred for validated lines.

• ODM: builds to a buyer's or another brand's spec; acceptable if the spec and QC are tight.

• Trading company: no factory; you pay for distance and lose direct engineering support.

The factory audit checklist

• Machine tools: CNC machining of the turret, not manual boring — ask for the turret runout spec (target < 0.02 mm).

• Welding & surface: 316L contact parts, weld certs, Ra ≤ 0.8 µm finish.

• Control cabinet: proper segregation, documented PLC/SCADA with CSV capability.

• Test bay: a running press under load during your visit — not a static showroom unit.

• Reference sites: at least two operating plants you can call, ideally in your region.

Quality tiers and what they cost

Measured supplier comparison (two anonymized bidders)

Supplier B looked cheaper and faster; the reject rate and slow support erased the saving within two batches.

Compliance the manufacturer must prove

Require CE (Machinery Directive 2006/42/EC), ISO 9001 certificate, and for device-linked products ISO 13485. EU-bound lines need EU GMP readiness and a builder that can run a credible FAT/SAT. Ask for a sample IQ/OQ protocol before you pay the deposit — if they cannot produce one, walk away.

Real cases (anonymized)

• Southeast Asia buyer: audited three bidders; chose mid-tier OEM after seeing a live test bay and two reference plants. Passed EU GMP first audit.

• EU CDMO: required full CSV and dual-row validation; only EU-equivalent tier qualified.

• Middle East plant: bought from a trading company to save 8%; lost direct support and waited 6 weeks for punches.

Pain points

• "Ghost factories" — a trader showing a rented showroom.

• Undocumented design changes between sample and production unit.

• Spare-parts discontinuity when the builder exits the model.

Misconceptions

• "Low price means good value." Total cost includes rejects and downtime.

• "CE label means EU-built." CE is a conformity declaration, not a birthplace.

• "A reference photo is a reference site." Insist on a callable plant.

Regional manufacturer profiles

Procurement pitfalls

• No factory audit before deposit — you fund an unseen shop.

• No callable reference site written into the contract.

• Vague INCOTERMS and excluded spare parts in the quote.

FAQ

How do I tell OEM from trader?

Ask to see the turret being machined and the design files; a trader cannot show either.

What turret runout should I accept?

Target below 0.02 mm; above 0.04 mm expect weight variation trouble.

Is a cheaper press ever right?

For non-export, low-risk products, yes — but write RSD and reject limits into the SAT.

What compliance docs are non-negotiable?

CE, ISO 9001, and a sample IQ/OQ protocol; ISO 13485 if a device is involved.

How important is a reference site?

Critical — a callable operating plant beats any brochure.

Should I audit in person?

Yes for mid/high tier; for entry tier at least a live video walkthrough of the test bay.

What about after-sales in the Middle East/Southeast Asia?

Confirm a regional service partner and a written response SLA before signing.

Can a mid-tier builder meet EU GMP?

Many can, if they deliver full validation docs and you run a proper FAT/SAT.
