Manufacturing Excellence at Scale

Located in Huangyan District, Taizhou — known globally as "Mold Town" — our 15,000 square meter facility represents three decades of continuous investment in people, equipment, and process optimization.

Every mold that leaves our facility undergoes rigorous quality checks at every stage of production, from raw material inspection through final trial run verification.
