MOS has over 35 years of experience in high-precision tooling and injection molding for cutting-edge technology and medical device companies. We started as a high-end custom tooling manufacturer for the semiconductor industry in 1974.

By 2009, we had received both our ISO 13485:2003 certification and the State of California Department of Health certification for medical device manufacturing.
After this much history delivering custom plastic injection molding products for high tech and medical industry leaders, we have learned a few things:
