A die casting surface finish can provide durability, protection and a decorative appearance. Because surface finishing options range from appearance to performance, it is best to discuss your application needs with us early in the design phase. The specific features of many designs have an impact on the surface finish. For example, parting lines, ejector pins, and gates can affect the end result. With over 75 years of die casting surface finishing expertise, our engineers will evaluate your requirements to recommend the best design and finishing options.
