Typical component families for professional coffee machine builders — boiler bodies, group head parts and PEEK/POM mechanism components in 304, brass and engineering plastics — supplied in series from 1,000 pieces.
| Boiler bodies | 304 stainless, stamped + turned |
| Group head parts | Brass, 304, Swiss-turned |
| Mechanism components | PEEK / POM, turn-milled |
| Batch range | 1,000–10,000 pcs per family |
| Tolerance scheme | DIN ISO 2768-mK, drawing fits |
| Documentation | EN 10204 3.1, food-contact-grade docs |
Professional coffee machine builders combine pressure-bearing boiler components, precision group head parts and food-contact mechanism components — often in batches of 1,000 to 10,000 pieces with a mix of stamped and turned geometries. Materials span 304 stainless for wet and thermal zones, brass for group heads and fittings, and engineering plastics (PEEK, POM) for sliding and insulation functions.
Each material brings its own process: stamped boiler bodies with turned ports, Swiss-turned group head components with fine surface requirements, and PEEK/POM parts machined with thermal management to hold dimensions on plastics.
| Component (IT / EN) | Typical material | Process | Typical batch |
|---|---|---|---|
| corpi caldaia (boiler bodies) | 304 stainless | stamping + turning | 1,000–10,000 pcs |
| particolari erogatore (group head parts) | brass, 304 stainless | Swiss-type turning | 1,000–10,000 pcs |
| meccanismi PEEK / POM (PEEK, POM mechanism parts) | PEEK, POM | turn-milling | 500–5,000 pcs |
Food-contact surfaces are documented per the material grade; cleaning and packaging requirements are confirmed per drawing.
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.
Which materials do you recommend for wet and thermal zones?
304 stainless for boiler and wet components, brass for group heads and fittings, and PEEK/POM for sliding and insulation functions — grade selection is confirmed per drawing.
Can you combine stamped and turned parts in one delivery?
Yes — stamping and turning are both in-house processes, so mixed component families ship as one package with a single documentation set.
What batch sizes are typical?
1,000–10,000 pieces per family with recurring monthly series for established machine platforms.
Do you support food-contact documentation?
Yes — material certificates and food-contact-grade documentation are provided per shipment.
