From a die casting shop to your manufacturing partner
We started in 2002 as a small die casting workshop in Xiamen. Over the years, we built up our capabilities piece by piece
—mold making, aluminum and zinc die casting, CNC machining, and surface finishing—until we could manage the full production chain under one roof. In 2018, we moved into Langyuan Industrial Park in Zhangzhou and began operating globally as Longwin Metal.
Today, we are an integrated ODM/OEM manufacturer serving automotive, industrial automation, electronics, and marine clients who need custom metal parts made right and delivered on time.
Our Certificates
We guarantee the top quality of our materials, the reliability, expertise, and our company's customer-oriented working procedures - this is surety for our customers.
