In the field of automotive parts manufacturing, Automotive Roof Racks not only bear load-bearing functions but also serve as important design elements for SUV and station wagon models. As a professional blow mold manufacturer, our blow molded automotive roof rack moulds utilize advanced CAD/CAE/CAM design software and high-precision CNC machining equipment to provide customers with lightweight, high-rigidity, and aesthetically superior roof rack mould solutions.













Professional Design, Precise Matching
Using advanced design software such as Pro/E and UG, combined with the characteristics of the blow molding process, we optimize the wall thickness distribution, rib structure, and appearance curvature of roof rack products. This ensures that products meet load-bearing requirements while achieving lightweight goals, aligning with the automotive industry's pursuit of fuel economy and environmental performance.
Premium Materials, Uniform Heat Conduction
Mold cores are manufactured from high-performance mould steels such as German 7075 aluminum alloy, imported P20, and 2738, ensuring excellent thermal conductivity and wear resistance. Uniform heat conduction ensures consistent temperature distribution of the parison during the molding process, effectively improving product surface quality and dimensional stability.
Precision Machining, Long Service Life
Equipped with high-precision engraving machines, CNC milling machines, dual-head EDM machines, and other precision processing equipment, we ensure accurate mold cavity dimensions and tight parting line fit. The moulds have a long service life, meeting the demands of high-volume continuous production.
Reliable Load-Bearing, Excellent Performance
Optimized rib structure design and uniform wall thickness distribution enable the molded roof rack products to possess excellent load-bearing capacity. They meet strict manufacturer load and deformation requirements, ensuring safety and reliability during dynamic driving and static loading conditions.
Smooth Surface, Outstanding Appearance
Mold cavities undergo fine polishing treatment, resulting in molded products with high surface smoothness and excellent appearance texture. They meet the stringent aesthetic requirements of automotive exterior parts, enhancing the overall visual quality of the vehicle.
