Injection Molding Design Guide

Injection molding produces high quality parts by forcing heated thermoplastics into a mold cavity to create the desired component. Quickparts provides traditional injection molding services, with capabilities ranging from prototype through production quantities, multi-cavity tooling, tight tolerances, over-molding and secondary post-molding operations.
