Food machinery builders — many born from plate workshops — buy stainless hoppers, conveyor components and hygienic fittings in small batches, and value a partner who answers small orders seriously. Small pilot quantities are welcome and quoted with the same discipline as volume, so qualification never requires a large commitment. One dedicated technical contact answers quoting, production and delivery questions from the first drawing through running supply.

| Tolerance scheme | ±0.005 mm, DIN ISO 2768-mK |
| Documents | EN 10204 3.1, dimensional report |
Plate-work-born machinery builders buying stainless components in small serious batches — and that defines how the buying actually works. Builders who grew from plate workshops know exactly what good stainless component work looks like — and reward the partner who answers small orders with the same seriousness as big ones. In practice this means drawings or samples go out, an itemized quotation comes back within 48 hours, and the first articles prove the process before volume is discussed. Lead times are stated on the quotation and held: samples in 7 to 15 days, series deliveries DDP in 5 to 8 days by air including customs clearance.
Builders who grew from plate workshops know exactly what good stainless component work looks like — and reward the partner who answers small orders with the same seriousness as big ones. Behind that sits the machinery that makes it repeatable: certified processes, material certificates with heat-number traceability on every batch, and a dedicated technical contact who handles quoting, production and delivery questions from first drawing to running supply. Lead times are stated on the quotation and held: samples in 7 to 15 days, series deliveries DDP in 5 to 8 days by air including customs clearance.
| Component (IT / EN) | Typical material | Process | Typical batch |
|---|---|---|---|
| Hoppers & trays | 304 | Sheet + machining | 100–2,000 |
| Conveyor components | 304/316 | Turning + milling | 500–10,000 |
| Nozzles | 316 | Sliding-head turning | 500–10,000 |
| Hygienic fittings | 316 | Sliding-head turning | 1,000–20,000 |
Per-drawing production; surface treatments through audited partners, documented in the batch file. Certificates and dimensional reports accompany every delivery, not just the first article.
The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Tooling, program revisions and inspection records are kept on file so that call-offs remain consistent with the approved first article.
Engineering changes — material substitutions, tolerance updates, plating or packaging changes — are handled as controlled changes against the same records.
DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Plating, cleanliness and packaging requirements are confirmed per drawing.
What are the payment and delivery terms?
New relationships start with 30 percent on order and 70 percent before shipment, or an irrevocable letter of credit for framework values. First articles ship in 7 to 15 days, and series orders deliver DDP in 5 to 8 days by air including customs clearance, or 35 to 45 days by sea for planned call-offs against forecast.
Which certificates do you hold?
IATF 16949 and ISO 9001:2015 certified by Intertek, plus ISO 14001:2015. Material certificates to EN 10204 3.1 with heat-number traceability accompany every batch, and RoHS and REACH declarations are available for all deliveries on request. First-article samples include the same document package. Lead times are stated on the quotation: samples in 7 to 15 days, series deliveries DDP in 5 to 8 days by air.
Can you reproduce parts from a sample?
Yes. Send the worn or broken component; we measure it, reproduce the geometry, and deliver a dimensional report with the first article in 7 to 15 days. The stored specification then runs all repeat orders, so emergency reproduction becomes a planned spares item with a fixed price. Lead times are stated on the quotation: samples in 7 to 15 days, series deliveries DDP in 5 to 8 days by air.
How is quality documented?
Every batch ships with material certificates carrying the heat number and a dimensional report covering the features you flag as critical, and the identical format repeats on every delivery so your files stay consistent across programs and years. Lead times are stated on the quotation: samples in 7 to 15 days, series deliveries DDP in 5 to 8 days by air.
