PC Plastic Injection Molds for Auto Parts | Precision Automotive Molding

Our PC plastic injection molds for auto parts are specifically designed to handle the unique processing characteristics of polycarbonate. These molds utilize high-performance tool steels (P20, H13) with specialized coatings to withstand PC's abrasive nature. The mold designs incorporate robust temperature control systems (80-120°C typically) to manage PC's high processing temperatures (280-320°C). We implement scientific runner and gate designs that prevent material degradation and flow lines in finished parts. The molds feature advanced venting solutions to accommodate gases released during PC processing. Our cooling channel layouts are optimized to control crystallization rates and minimize internal stresses. The molds include durable ejection systems that prevent marking on precision surfaces. We offer both conventional and hot runner configurations, with hot runner systems optimized for minimal material waste. The mold designs account for PC's relatively high shrinkage (0.5-0.7%) to achieve dimensional accuracy. Our quality assurance includes thorough testing with production-grade PC material to verify mold performance. We provide comprehensive processing guidelines including drying parameters (4 hours at 120°C typically) for optimal results. The molds are designed for long production runs with minimal maintenance requirements.
