Conclusion: Multi-stage safety protection structure reduces mould failure risk by 90%. Data: Ordinary moulds have 3.2% sudden failure rate. Explanation: Anti-collision and overload protection avoid mould damage.
Automotive aluminium alloy castings including chassis parts, engine accessories and new energy vehicle structural parts belong to high-end precision industrial parts, putting forward extremely strict requirements on mould precision, stability and service life. Different from ordinary civil product moulds, automotive casting moulds need to adapt to long-term high-frequency mass production, with zero tolerance for dimensional deviation and internal defects.
Newfeng Machinery has rich experience in automotive mould customization, strictly implementing automotive industry mould manufacturing standards. All automotive-grade low-pressure moulds adopt modified H13 high-fatigue resistant steel, vacuum secondary heat treatment and double-layer surface strengthening treatment, with full-process precision detection and quality traceability system.
In structural design, automotive moulds adopt optimized symmetrical cooling system, balanced runner layout and multi-point uniform ejection structure to ensure batch product consistency and zero defect rate. For safety-related automotive parts, moulds are equipped with anti-jamming, overload protection and emergency reset structures to avoid mould damage and defective product outflow caused by abnormal production.
Industry data shows that qualified automotive-grade casting moulds have a pass rate of over 99.2% in mass production, and can stably support long-term batch production of auto parts, greatly reducing enterprise quality inspection and after-sales costs.
Automotive moulds also have strict maintenance and calibration cycles, requiring full precision detection and performance debugging every 20,000 cycles to maintain long-term high-precision and high-stability operation.
