Mold Manufacturing

Sino-Mold Manufacturing

Molds are molded structural components used for injection molding and pressing of polymer composites. The design and geometry of the mold determine the shape, texture, roughness, density, and strength of the future product. Molds are used to mass-produce structurally identical plastic products.

Sino-Tech specializes in designing and manufacturing molds for various applications, including automotive parts, medical devices, consumer electronics, and industrial plastic parts. We have extensive experience producing high-precision molds for products such as automotive lighting, bumpers, decorative strips, LED lenses, medical pipette tips, and centrifuge tubes.

Sino-Mold excels in producing automotive lighting molds. And is a leader in China’s mold manufacturing industry. Our team comprises 30 plastic mold engineers and 45 skilled craftsmen specializing in making precision plastic molds.

Sino-Mold sources steel from renowned suppliers such as LKM, Gröditz, and ASSAB. Depending on the mold-making requirements, we choose steel from the USA and Japan for our molds. Reliable steel suppliers, skilled technicians, and state-of-the-art precision mold-making equipment ensure the high quality of our molds.

Sino-Mold can produce 500 sets of molds annually, of which about 50% are used in the automotive industry. The remaining capacity makes molds for medical devices and consumer electronics.
