Precision CNC Machined Components for High-Tech Equipment
Precision CNC machined components for robotics, automation, optical & photonics, sensors, satellite communication and specialized equipment — from prototype and pre-series to recurring production.
We Support Equipment Manufacturers
We manufacture the precision parts inside your machines — not just loose components. Six core industries where we are a long-term supply partner.
Industrial Automation
Precision components for automated production equipment and assembly systems.
Special Machinery
Machined parts for custom machine builders and Sondermaschinenbau.
Robotics
Robotic arm components, housings and structural parts for robotics manufacturers.
Semiconductor Equipment
PEEK, PVDF and special alloy components for vacuum and semiconductor machinery.
Inspection & Testing
Precision inspection components for measurement and test equipment.
Optical & Photonics
Optical mechanical components for laser, fiber and photonics equipment.
Core Capabilities
Precision machining across the processes your equipment components actually require.

Your Trusted Partner for Precision Machining of Advanced Materials
We specialize in the materials other shops struggle with — Kovar®, Permalloy, tungsten alloys, carbon fiber composites and high-performance plastics. When we can hold tolerances on these, aluminum, stainless steel and titanium become routine.
Advanced & Difficult-to-Machine Materials Core Specialty
Standard Engineering Metals — Also Routine
Most equipment manufacturers need both everyday metals and advanced materials in the same project. We machine the full range in-house — so you do not have to split your BOM between a standard shop and a specialty shop.
In-House Metrology & Material Verification
Quality is verified, not promised. Our in-house inspection lab confirms both the dimensions and the material of every critical batch before it leaves the floor — backed by ISO 9001:2015.
Zeiss CMM Inspection
Dimensional verification on a Zeiss coordinate measuring machine — full inspection, tight-tolerance reporting and first-article inspection (FAI) for complex and 5-axis components.
Material Spectrometer
A benchtop raw-material spectrometer verifies the chemical composition of incoming stock against the specified grade and EN/DIN number — so the certificate matches the metal in your part.
Certificates & Traceability
Material certificates (EN 10204 3.1), dimensional inspection reports and full batch traceability for semiconductor, optical and high-reliability equipment.
Beyond Machining — Engineering Services
The support on-demand platforms do not offer. This is where a long-term manufacturing partner earns the relationship.
Special Materials Core
Specializing in Kovar®, Permalloy, tungsten alloys, carbon fiber composites and high-performance plastics that most platforms outsource or refuse.
Quality Rescue Unique
When a batch fails inspection, we re-inspect, find root cause, and rework or replace — including parts made by another supplier.
Factory Audit Support Unique
Material certifications, traceability and engineering evidence so you pass your customer's supplier audit.
Custom Packaging Unique
Labeled kits, batch-segregated packs, ESD-safe and cleanroom packaging for semiconductor and optical use.
Assembly & Turnkey Unique
Sub-component assembly and multi-part-number supply — one accountable partner instead of five.
Local EU Support DACH
Our German engineering office provides in-region repair, after-sales and audit support.
A Manufacturing Partner, Not a Part Vendor
What changes when your supplier is built for your equipment program, not for quoting and shipping loose parts.
| Dimension | On-Demand Platform | ProtoTech |
|---|---|---|
| Special materials | Often outsourced / premium | Core competency |
| Quality failure | Not responsible | On-site rescue + re-inspection |
| Inspection | Basic / self-reported | Zeiss CMM + material spectrometer, in-house |
| Customer audit | Not involved | Documentation + engineering support |
| Packaging | Standard bubble mailer | Custom / kitted / cleanroom |
| Delivery | Loose parts | Assembled, turnkey |
| EU presence | Cross-ocean only | Local engineering office (Germany) |
| Relationship | One-off transaction | Long-term supply partner |
Local Engineering Presence in Germany
Through our European engineering partner, our European engineering team provides prototyping, repair assistance and after-sales support — and joins you on-site for quality and audit matters. When your supplier fails, we are in the region, not across an ocean.
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
