Low Pressure Die Casting (LPDC) is the most mainstream molding process for passenger car aluminum wheel hubs in the global market, with mature technology, stable quality and high cost-performance. LPDC dedicated molds are professionally optimized for low-pressure steady-pressure filling characteristics, completely different from gravity casting and high-pressure casting molds, and have irreplaceable advantages in passenger car wheel hub mass production. Zhejiang Xinfeng Machinery’s standardized LPDC molds have been widely applied in mainstream automobile supporting factories.
High-density uniform molding is the core advantage of LPDC molds. Relying on stable low-pressure filling technology, the aluminum liquid fills the mold cavity slowly and evenly without strong turbulence, making the internal density uniformity of castings reach 99.5%, effectively avoiding loose structure, micro-pores and other internal defects. Compared with gravity casting products, LPDC castings have higher structural compactness and better mechanical properties, meeting passenger car safety standards.
Low defect rate and excellent surface quality reduce subsequent production costs. The low-turbulence filling mode greatly reduces gas entrainment and oxide inclusion problems, controlling the overall defective rate of wheel hub production below 0.13%. The high-precision coated cavity realizes high-finish one-time molding, reducing subsequent manual polishing and finishing workload by 34%, saving a lot of labor and time costs for casting enterprises.
Excellent cost-performance and wide compatibility make LPDC molds mainstream in the industry. Compared with high-precision CPC molds, LPDC comprehensive production cost is 18% lower, suitable for large-scale batch mass production. Standardized structural design enables the molds to adapt to 92% of mainstream passenger car wheel hub specifications on the market, with strong versatility and stable production capacity, occupying 68% of the global passenger car wheel hub mold application market.
