Dongguan, China – As electric vehicle (EV) battery packs demand higher energy density and lighter structures, injection moulding challenges intensify. For BYD’s electric vehicle battery compartment component – made of PA66 BASELL – the part features deep cavities, a bone grille wall thickness of only 0.7mm, and requires strict moulding control. The solution: a precise injection mould design that integrates H13 cavity/core, LKM mould base, Moldmaster 4‑point hot nozzle (with hot runner to cold runner transfer), and beryllium copper inlays for accelerated cooling and trapped gas prevention.
High-Precision Injection Molding for Electric Vehicle Battery Storage Components Part Name: Electric Vehicle Battery Storage Material: PA66 (BASELL) – High-temperature, flame-retardant nylon for superior mechanical and thermal stability Mold Type: Insert Molding / Injection Molding (Multi-Cavity Production) Cavity & Core: H13 Tool Steel (Hardened to 48-52 HRC for extended mold life) Mold Base: LKM Standard (DME-compatible for global serviceability) Hot Runner System: Moldmaster 4-Point Hot Nozzle (Precision temperature control for consistent fill) Tolerance: ±0.2mm (Critical for battery sealing surfaces)
