Our Story
Founded in2012, we started as a precision mold maker serving local manufacturers. Our focus was simple: build high-quality molds that run reliably and produce perfect parts.

Over the years, we listened to our customers. They asked for more — injection molding, surface finishing, assembly. So we expanded. We added 80+ injection molding machines, built a Class 100,000 cleanroom, established in-house mechanical and electronic engineering teams, and set up 6 assembly lines.

Today, we are a true one-stop manufacturing partner serving customers from around the world. But our core belief remains the same: deliver quality, simplify complexity, and build lasting partnerships.
