About Weiyon Industry

Weiyon Industry began as a small machining workshop in central Taiwan in the 1980s — when Taiwan's manufacturing sector was just taking off, and every process still relied on the senior machinist's hands-on judgment. Our origins reflect that era: starting with a drawing, a piece of stock, and a set of files.

Over four decades, the industry transformed many times. CNC machines replaced conventional lathes; semiconductors, aerospace, and medical became new customer markets; materials expanded from stainless steel and aluminum to titanium and other difficult-to-machine alloys. We changed with it — from the nervousness of installing our first CNC mill to the confidence of running complex multi-axis paths today, every upgrade carried hours of relentless learning.

But some things never changed. Daily machine checks before startup. A measurement record for every dimension. A batch number traceable on every piece of material. These seemingly old-fashioned disciplines are how we keep our promise on quality. When customers order, they receive more than parts — they receive 40 years of uncompromising commitment.

Today's Weiyon Industry is built on the same conviction: get every part right. From one-off prototypes to volume production, from Taiwan-domestic to overseas orders, from traditional mechanical parts to advanced semiconductor components — no matter the size of the project, we treat every drawing as if it were our first.
