1.Start with a product concept and determine measurements.
2.Draft plans, usually on a Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) system in 2D and 3D models.
3.Analyze the production elements with software solutions, looking for areas of flow, dimension, and geometry that may cause problems such as high pressure fills, short shots, weld lines, poor cooling, part distortion, air traps, sink marks, bad gate locations, etc. May also run a working sample with 3D Printing, Stereolithography, or other system for rapid prototyping.
4.Cut the mold using Computer Numerical Control (CNC), Electrical Discharge Machines (EDM) or other methods. Determine the appropriate quality steel or aluminum for the appropriate mold class. Verify the product meets specifications.
5.Begin production.
