Most defects are preventable, and the earlier in the process you address the root cause, the cheaper it is to fix.</p> <p>Here are the five most common injection molding defects, their root causes, and what you and your mold supplier can do to eliminate them.</p> https://www.jbrplas.com/posts/dfm-guide/ Wed, 05 Feb 2025 00:00:00 +0000 https://www.jbrplas.com/posts/dfm-guide/ <p>Design for Manufacturability (DFM) is the practice of designing parts with the manufacturing process in mind from the beginning. For injection molding, applying DFM principles during design — rather than retrofitting them after a mold is built — is the single most effective way to reduce tooling cost, shorten lead time, and eliminate production defects.</p> <p>This checklist covers the eight most critical DFM rules for plastic injection-molded parts.</p> <h2 id="1-wall-thickness--the-foundation-of-a-good-mold-design">1. Wall Thickness — The Foundation of a Good Mold Design</h2> <p><strong>The rule:</strong> Keep wall thickness as uniform as possible throughout the part. The ideal thickness for most applications is <strong>2–4mm</strong>. Avoid sections thicker than 6mm without coring.</p>
