No matter how well a mold is designed or how precisely a machine is calibrated, injection molding defects happen. The difference between an average shop and a great one isn’t zero defects — it’s knowing what causes them and how to fix them fast.
Design for Manufacturing: 7 Critical DFM Rules for Injection Molded Parts
Design for Manufacturing (DFM) is one of the most overlooked yet most impactful stages in the injection molding process. When done right, DFM can reduce tooling costs by 20-40%, shorten cycle times, and nearly eliminate post-molding defects. When ignored, it leads to expensive mold modifications, delayed timelines, and parts that simply don’t work as intended.
