New energy vehicle aluminum alloy structural parts such as control arms, knuckles and battery brackets are core load-bearing components, with far higher requirements on casting density, mechanical strength and dimensional stability than traditional automotive parts. The supporting casting molds need to adopt targeted technical optimization to meet EV industry safety and durability standards. Zhejiang Xinfeng Machinery optimizes mold structures for high-load EV structural parts, realizing high-quality mass production of new energy automotive castings.
High structural rigidity is the basic requirement of EV structural part molds. In the production of high-load chassis parts, the mold needs to bear long-term stable pressure impact. The optimized reinforced frame structure controls overall deformation below 0.05mm after long-term operation, avoiding dimensional deviation of castings caused by mold deformation and ensuring the assembly accuracy and load-bearing capacity of structural parts.
Ultra-low defect design is the core technical indicator. Traditional automotive castings allow a porosity rate below 0.4%, while EV load-bearing structural parts require porosity strictly below 0.15%. The optimized venting and gating system of professional molds effectively eliminates internal gas and impurities, ensuring dense casting structure, improving product fatigue resistance and impact resistance, and meeting vehicle driving safety standards.
Precision cooling system and ultra-precision processing further improve product stability. The refined multi-point cooling structure controls mold temperature difference within 60℃, realizing uniform solidification of molten metal and avoiding residual stress concentration. The overall machining tolerance is controlled within ±0.01mm, which fully adapts to the precise assembly requirements of new energy vehicle chassis systems. Matched with high-wear-resistant mold steel and special heat treatment process, the service life of EV dedicated molds stably reaches 180,000+ cycles.
