Custom Machine Components, Machined to Print

Special machinery lives up to its name: every machine is a one-off, and every part has to work the first time. We machine custom components for machine builders who cannot wait for catalogue parts — with DFM feedback that catches problems before they reach the shop floor.

Why ProtoTech

Why equipment manufacturers choose us

One-off friendly, series capable

From single prototype parts to small recurring series — the same engineering attention on both.

DFM that saves the project

Our engineers flag tolerance stacks, material risks and machining constraints during quoting, not after scrap.

Complex parts, multiple materials

Multi-process parts spanning metals and engineering plastics, machined complete and inspected as assemblies of features.

How we work

From Drawing to Delivered Part

A transparent, engineering-led process built for long-term supply programs — not one-off transactions.

1

Submit & Review

Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.

2

Quote & Material Plan

You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.

3

Machine & Inspect

In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.

4

Deliver & Support

Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.

FAQ

Frequently asked questions

Yes — one-offs are a core part of our business. You get the same DFM review, material verification and CMM inspection as a series program.
Yes — we routinely supply matched sets of aluminum, stainless and engineering-plastic components, so interfaces and tolerances are consistent across the build.
DFM review at quotation, material verification at incoming inspection, first-article approval before any series — every step documented.

What happens after you send your files

  • Within 1 business day an engineer — not a salesperson — reviews your drawings and replies.
  • DFM review: tolerances, material and risk flags, before any cutting begins.
  • Your quote includes a material-verification plan: grade, EN/DIN check, certificate strategy.

Critical features are verified in house · material chemistry confirmed by spectrometer · EN 10204 3.1 certificates available.

Recurring programs and orders of 1,000+ pcs are prioritised by our engineering team.
The number of parts per order — it lets us price tooling and batch setup correctly instead of guessing at a range.
Several different parts? Email your list and drawings to ellie@prototech-machining.com and we will quote them together.
