SPI Mold Classifications

A Guide for SPI Mold Classifications

SPI Mold Classifications were originally defined by the SPI (Society of the Plastics Industry) which is now part of the Plastics Industry Association and are widely used in North America and globally. At True Position Plastics we can design and build all classifications of molds from Class 101 to 105. Contact us below, or email us directly at justin@truepositionplastics.com
