China Plastic Mould for Bumpers - High Precision Suppliers and Factory for Automotive Injection Molding
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.
High precision and durability
◎ P20 steel mold core, dimensional error ±0.2mm, lifespan over one million cycles.
High-efficiency cooling
◎ The water cooling system reduces the molding cycle from 120 seconds to 60 seconds.
Flexible configuration
◎ Supports multiple cavities and adjustable partitions to adapt to different product specifications.
Advanced process
◎ Electrical discharge machining/wire cutting, surface roughness ≤ Ra0.4μm.
Stable demolding
◎ The dual system of pin ejector and ejector plate reduces the risk of mold sticking.
Automobile manufacturing
Mass production of bumpers for gasoline and new energy vehicles to meet pedestrian protection and lightweight requirements.
Customization needs
Quickly adjust molds to adapt to model changes or special designs.
Industrialized production
A single mold can support continuous injection molding of more than 500,000 bumpers.
