Components for semiconductor and vacuum equipment: chamber parts in 6061/316, CF flanges in 316LN, Kovar 4J29 and PEEK machined parts. Low-volume, high-precision batches from 50 pieces.
| Vacuum chamber parts | 6061 aluminum, 316, milled |
| CF flanges | 316LN, turned |
| Kovar parts, PEEK parts | 4J29, PEEK, turned/milled |
| Batch range | 50–5,000 pcs per family |
| Tolerance scheme | DIN ISO 2768-mK, seal surfaces to drawing |
| Documentation | EN 10204 3.1, material certificates |
Semiconductor and vacuum equipment builders order small batches of high-precision components — vacuum chamber parts, CF flanges, feedthrough components — where the differentiator is not volume pricing but rare material capability and process discipline. Kovar (4J29) for glass-to-metal seals and PEEK for insulating, outgassing-critical parts are the two materials that most shops avoid.
Both are established in our portfolio. Kovar turning requires controlled cutting conditions to preserve the seal-surface quality; PEEK machining needs thermal management to hold dimensions on an insulating material. Batches from 50 pieces fit the equipment-builder pattern.
| Component (DE / EN) | Typical material | Process | Typical batch |
|---|---|---|---|
| Vakuumkammer-Komponenten (vacuum chamber components) | 6061 aluminum, 316 | milling | 50–1,000 pcs |
| CF-Flansche (CF flanges) | 316LN | turning | 100–2,000 pcs |
| Kovar-Teile (Kovar parts) | Kovar 4J29 | Swiss-type turning | 500–5,000 pcs |
| PEEK-Komponenten (PEEK components) | PEEK | turn-milling | 200–2,000 pcs |
Kovar and PEEK machining are differentiating capabilities in this vertical — both are established processes with controlled cutting parameters.
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. Batch sizes follow the table above — from single spare parts to tens of thousands of pieces per order, depending on the component family.
For repeat orders, tooling, program revisions and inspection records are kept on file, so call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, 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. Surface treatment, cleanliness and packaging requirements are confirmed per drawing.
Do you machine Kovar (4J29)?
Yes — Kovar turning with controlled cutting conditions is an established process, typically for glass-to-metal seal components.
Can you machine PEEK without losing dimensions?
Yes — PEEK machining requires thermal management; dimensional strategy is agreed per drawing before sampling.
What CF flange finishes do you deliver?
Seal surfaces are machined to the drawing specification for the flange size; values are confirmed before production.
What batch sizes fit equipment builders?
50–1,000 pieces for chamber components, up to 5,000 for Kovar and PEEK part families.
