Sino Mold Mold Design

Mold design plays a very important role in the manufacturing process of plastic injection molding. It includes the whole process of turning raw materials into usable molds. In mold design, engineers must deeply understand product design, material properties, and the mold manufacturing process. This is the only way to design an injection mold that is both functional and aesthetically pleasing.

Sino-mold’s professional team has a wealth of experience in mold design, and our engineers will work closely with you during the mold production process to match the details of the mold to the product design and our manufacturing process. We also offer dozens of materials to choose from, including ABS, Ultem, PC/ABS, PEEK, HDPE, PET, TPE, PET, nylon, polyethylene, and more. To meet your needs for injection molded products in different industries.

We strictly comply with ISO9001:2005 certification in every aspect of mold production to ensure that every product meets quality standards. We are equipped with CMM, 2D Projector Parts Inspection, and other quality inspection equipment to ensure that the molds meet strict tolerances. Ultimately, we ensure that your molds are robust and have a long service life, helping you maximize your profitability. Contact us today for a free quote.
