metal-plastic hybrid components requires balancing wall thickness ratios, draft angles, and metal retention geometry to prevent physical joint failure. Incorporating metallic studs, threaded brass bushings, or conductive copper terminals directly into plastic bosses introduces severe localized hoop stress during polymer cooling contraction. Inadequate boss wall thickness or sharp internal corners trigger stress-cracking around embedded metal elements under mechanical road vibration or thermal shock testing. Establishing standardized CAD design rules during initial 3D modeling eliminates costly tool modifications and ensures high-yield series manufacturing. This technical DfM guide analyzes boss-to-insert wall proportions, knurling interlocks, and mold shut-off sealing geometry. Table of Contents 1.
