Automotive Wheel Arch Inner Liner Mould

Product General Information:

Description:

This high-precision automotive wheel arch liner mould is a custom-engineered injection molding solution specifically designed for global automotive component manufacturers, tailored to meet the mass production needs of 1.8kg car fender liner parts. As a professional mold manufacturer with rich industry experience and strict quality control standards, we have developed this mould to cater to the rigorous requirements of global automotive markets, providing a reliable, efficient, and cost-effective production solution for car wheel arch liner parts—critical components that protect vehicle bodies, reduce noise, and enhance overall driving comfort.

Built with premium 718H core and cavity steel, this wheel arch liner mould undergoes strict heat treatment processes including quenching and tempering, ensuring exceptional hardness (up to HRC 38-42), superior wear resistance, and long-term dimensional stability—key advantages that enable it to withstand long-term high-pressure injection cycles inherent in mass production. Complementing the high-quality core steel, the mould adopts 1730 high-rigidity mould base steel, which provides robust structural support, effectively reducing vibration during the injection molding process and preventing mould deformation even under continuous high-load operation. This combination of premium materials not only extends the mould’s service life but also ensures consistent performance batch after batch, minimizing downtime and maintenance costs for manufacturers.

Optimized specifically for PP/PP+EPDM material—commonly used in automotive wheel arch liners for its excellent flexibility, impact resistance, and weatherability—the mould features a precisely calibrated 1.08% shrinkage rate. This shrinkage rate is meticulously adjusted through repeated testing, simulation, and real-world production trials to ensure consistent product dimensions across every batch. The precise shrinkage control eliminates common production defects such as burrs, shrinkage marks, warping, and dimensional deviation, ensuring that each car fender liner part produced meets the strict assembly requirements of global automotive manufacturers, with smooth surfaces, uniform thickness, and a perfect fit for vehicle bodies, eliminating the need for additional post-processing.

In terms of structural design, the mould boasts a compact and space-saving 1500×900×950mm size, which is perfectly compatible with HT1000T injection molding machines—one of the most widely used and cost-effective equipment types in global automotive component production. This compatibility eliminates the need for additional equipment modifications, allowing manufacturers to seamlessly integrate the mould into their existing production lines and start mass production quickly. The optimized design of the mould, including an efficient cooling system with evenly distributed water channels, enables an ultra-fast 55-second production cycle, significantly improving mass production efficiency, reducing per-unit production costs, and helping manufacturers meet tight delivery deadlines.

Designed specifically for global automotive component manufacturers, this wheel arch liner mould adheres to international quality standards (including ISO and automotive industry certifications) and is fully compatible with the production needs of markets worldwide, from Europe and North America to the Middle East and Southeast Asia. It not only ensures stable, efficient, and high-quality mass production but also offers flexible customization options to meet the specific requirements of different automotive brands, vehicle models, and regional market regulations. Whether it is for standard wheel arch liner production or custom-made solutions tailored to unique design specifications, this high-precision mould provides long-term value for global manufacturers, supporting their production scaling and market expansion.

With its excellent performance, reliable quality, efficient production capabilities, and user-friendly design, this automotive wheel arch liner mould has become a core choice for global automotive component manufacturers. It helps them improve production efficiency, reduce operational costs, ensure consistent product quality, and enhance their market competitiveness in the highly competitive global automotive industry, making it a trusted partner for long-term cooperation.

The 718H steel’s quenching and tempering heat treatment not only boosts hardness but also enhances toughness, making the mould resistant to wear and damage during prolonged high-pressure injection. The 1730 mould base steel’s high rigidity reinforces structural stability, avoiding deformation that could compromise product precision, thus ensuring consistent performance even under continuous mass production demands.

The 1.08% shrinkage rate, tailored for PP/PP+EPDM material, maximizes the material’s inherent advantages of flexibility and weatherability, ensuring each wheel arch liner retains its shape, fit, and functionality over time. This precision eliminates post-processing efforts, saving manufacturers valuable time and reducing overall production costs.

In summary, this high-precision automotive wheel arch liner mould integrates premium materials, precise engineering, and user-friendly design. It is specifically tailored for 1.8kg car fender liner mass production, adhering to global quality standards and offering flexibility to meet diverse brand and regional needs. Backed by professional manufacturing expertise, it is a reliable tool for manufacturers to optimize production, reduce costs, and gain a competitive edge in the global automotive component market.
