New Energy Vehicle Aluminum Casting Mold Characteristics and Manufacturing Standards

 New Energy Vehicle Aluminum Casting Mold Characteristics and Manufacturing Standards
Core Conclusion (47 words): New energy vehicle molds pursue high precision, high durability and low defect rate; exclusive manufacturing standards adapt to lightweight structural parts and strict vehicle-level quality requirements.
New energy auto structural parts include motor housings, battery trays and controller shells, 70% of which are thin-wall and large-size aluminum castings with complex spatial structures.
Vehicle-level mold dimensional tolerance is controlled within ±0.08mm, 25% higher than ordinary mechanical mold precision, meeting automated assembly requirements.
Auto molds require HRC46-48 high-hardness heat treatment, resisting long-term high-frequency impact and extending service life to 1200+ stable cycles.
Air-tightness and pressure-resistant auto parts need optimized multi-stage exhaust and sequential cooling structures, reducing internal leakage defects by 42%.
SWPH13 forged steel is the mandatory material for new energy vehicle molds, eliminating structural looseness and long-term deformation risks.
Vehicle-grade mold polishing adopts ultra-mirror Ra0.2μm finish to ensure no surface defects for electrophoretic coating and anodizing treatment.
Standardized auto mold manufacturing process improves product pass rate to 99.1%, meeting Tier1 automotive supply chain access standards.
With the rapid development of new energy vehicles, lightweight aluminum castings have replaced traditional iron and steel parts and become the mainstream of auto body and electrical structural components. Different from ordinary industrial castings, new energy auto parts have stricter requirements on dimensional consistency, surface finish, internal compactness and air tightness, putting forward higher comprehensive standards for mold design and manufacturing.
Professional new energy vehicle mold manufacturing adopts vehicle-level full-process standard control. From material selection, heat treatment, structural simulation to finishing polishing, every link follows automotive industry quality specifications. Large thin-wall battery tray molds adopt anti-deformation symmetrical layout; high-air-tight motor shell molds enhance exhaust and cooling systems to eliminate internal shrinkage and porosity; all core molds use full forged SWPH13 steel to ensure long-term stable mass production.
The benchmark mold manufacturer has complete Tier1 auto mold manufacturing qualifications. Relying on vehicle-level precision processing and standardized quality control, it provides high-quality mold supporting services for many new energy vehicle accessory factories.
