    Frequently Asked Questions
    Q What materials can this car bumper mold process?
    This mold is designed for injection molding of PP (Polypropylene) and ABS (Acrylonitrile Butadiene Styrene) raw materials, making it highly versatile for producing car bumpers that meet both lightweight and impact resistance standards in the automotive industry.
    Q What is the dimensional accuracy and lifespan of the mold?
    The P20 steel mold core ensures a dimensional error of ±0.2mm, delivering high consistency across all produced parts. The mold is engineered for a lifespan exceeding one million molding cycles, making it ideal for long-term mass production.
    Q How does the cooling system improve production efficiency?
    The optimized water cooling system significantly reduces the molding cycle from 120 seconds down to 60 seconds — a 50% improvement. This enables faster throughput, lower energy consumption, and higher overall production efficiency for automotive exterior parts.
    Q Can the mold be customized for different bumper designs or vehicle models?
    Yes. The mold supports multiple cavity configurations and adjustable partitions, allowing quick adaptation to different product specifications, vehicle model changes, or special design requirements. This flexible configuration makes it suitable for both standard and custom bumper production.
    Q What gate and ejection systems are used in this mold?
    The mold uses a hot runner system combined with a normal side gate for optimal material flow and reduced waste. For ejection, a dual system consisting of a pin ejector and ejector plate is employed, which minimizes the risk of mold sticking and ensures smooth, stable demolding of each part.
    Q What types of automotive parts can be produced with this mold?
    This mold is primarily designed for front and rear bumpers for both gasoline and new energy vehicles, but it is also suitable for producing other automotive exterior parts such as door panels. With a 2-cavity configuration (left + right), a single mold can continuously support the injection molding of more than 500,000 bumpers.
