Metallic inserts composed of brass, copper, stainless steel, or aluminum exhibit thermal expansion behavior radically different from raw thermoplastics. Exposing mismatched hybrid assemblies to rapid temperature changes induces severe mechanical shear stress along the polymer-metal boundary. Thermal shock cycling can trigger micro-cracking in low-elongation plastics or cause interfacial delamination around metallic contact pins. This technical material guide reviews coefficient of thermal expansion (CTE) matching strategies, high-temperature resin processing, and raw material traceability protocols. Table of Contents 1.
