High-Precision Plastic Mould for Bumpers - Trusted China Suppliers and Factory for Automotive Parts
This mold uses injection molding to process PP/ABS and other raw materials into highly consistent car bumpers. Its core structure includes a P20 steel mold core, a 45# mold base, a hot runner gate, and a double-groove ejection system. Optimized cooling channels can shorten the molding cycle by 50%, meeting automotive industry standards for light weighting and impact resistance. It is suitable for mass production of exterior parts such as front/rear bumpers and door panels.
