DFM for Injection Molding: 10-Point Checklist for Engineers

Engineer reviewing DFM analysis of injection molded plastic part showing wall thickness gradients on CAD model

A mold modification costs between $500 and $20,000 depending on what needs to change and the tooling material. Most modifications are preventable. They happen because geometry that looked correct in CAD was not reliably producible by injection molding, and nobody caught it before the tool was cut. Design for manufacturability (DFM) is the process of […]
