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.

Innovative insert molding, mold layout, over mould, Two-shots Injection Mould, and stack mould technologies converge in PP Bottle Cap production
