By following these design principles, you can significantly lower tooling costs, decrease production time, and improve the quality of your molded parts.
Download a real DFM (Design for Manufacturability) checklist from a mold maker. Better yet, send your first design to a shop that offers free DFM analysis. Most do, because they want to sell you the mold — but they also want you to succeed. Here is the hard truth most engineers won't
What are you planning to use (ABS, Nylon, Polypropylene)?
Most "exclusive" guides emphasize these fundamental principles to avoid common defects like sink marks, warpage, or "short shots" (incomplete parts). (EN) eBook: Injection Molding Design Guide - Xometry Pro Download a real DFM (Design for Manufacturability) checklist
: Taper the vertical walls of your part. This allows the part to slide easily out of the mold without scratching or sticking.
: Different plastics shrink at different rates. For example, Polypropylene (PP) shrinks significantly more than Polycarbonate (PC)
