Who we are
ProtoTech Machining Co., Limited is an ISO 9001:2015 certified CNC manufacturer based in Shenzhen, China. We produce precision-machined components for robotics, industrial automation, semiconductor equipment, optical systems, inspection devices and special machinery.
Our customers are small and mid-sized equipment makers in Germany, Switzerland, Canada, the United States and Australia. They come to us when tolerances matter, when materials are difficult, and when they need a partner who reads drawings, asks questions, and stays with the program from first article to recurring production.
European presence
For customers in Europe, ProtoTech works with Tubacon GmbH, our local engineering partner in Germany. Tubacon supports DFM reviews, customer audits, quality re-inspection and after-sales service — so your supplier is present in your market, not an ocean away.
