New energy battery aluminum alloy castings have ultra-high requirements for air tightness, compactness and dimensional precision, which put forward higher design standards for supporting low-pressure casting mould. Different from ordinary automotive castings, battery shell and structural parts need long-term stable sealing performance, and tiny internal defects will lead to product scrapping. Xinfeng Machinery has mature customized mould solutions for new energy battery casting products.
Micro-defect control is the core of battery mould design. Battery castings have strict zero-porosity requirements. Ultra-fine exhaust structure and uniform filling runner design can completely eliminate micro air holes and loose structures, ensuring product internal compactness and air tightness.
Precise temperature field control guarantees structural stability. Battery shell parts have uneven wall thickness and complex sealing structures. Dense partition cooling system realizes synchronous solidification of thick and thin walls, avoids residual shrinkage stress, and prevents later deformation and air leakage.
Reinforced structural design adapts high-frequency mass production. New energy industry has large order volume and continuous production demand. Reinforced insert and anti-wear structure improves mould durability, reduces failure shutdown frequency, and ensures stable delivery of batch products.
