New Energy

The new energy industry places high demands on the reliability and production efficiency of power batteries, energy storage systems, and e-drive components. In parts such as battery top covers, explosion-proof valve bodies, busbars, copper-aluminum connectors, and insulation brackets, the precision of the punching process and the scrap ejection capability directly affect the continuous operation of automated production lines. ZHONGWANGDA (DONGGUAN) PRECISION MOLD CO., LTD. provides punching products including side scrap clearance holes, stepped holes, hexagonal holes, and bottom half-blanking holes, tailored to the materials used in the new energy industry (such as aluminum alloy, copper, nickel strip, and coated metals) and their thickness ranges. The company focuses on smooth scrap ejection and die life in actual stamping operations. For example, using a side scrap clearance stepped hole structure in a progressive die allows punching and step forming to be completed in one stroke, with scrap automatically cut and ejected sideways, reducing the risk of scrap accumulation in the die cavity. For steel holes on conductive connectors, burrs can be minimized by properly controlling the punching clearance, avoiding local discharge or assembly interference caused by burrs. For non-standard hole shapes, such as special-shaped explosion-proof holes or positioning anti-rotation holes, the company can provide custom design and manufacturing based on customer-supplied 3D data.

The punching products of ZHONG WANG DA can be applied in the new energy sector in the following scenarios:

• Side scrap clearance holes, side scrap clearance stepped holes: Used for side punching and scrap cutting on parts such as battery top covers, explosion-proof valve bodies, and busbars in progressive dies, enabling automated production.

• Hexagonal side scrap clearance holes: Suitable for machining hexagonal holes that require anti-rotation positioning, such as on insulation plates or fixing brackets in battery modules.

• Steel holes: Used for precision punching on conductive connectors such as copper bars, aluminum bars, and nickel strips, ensuring hole alignment and stable current-carrying area.

• Bottom half-blanking holes: Suitable for half-punched structures at the bottom of battery casings or on end plates, facilitating subsequent riveting or welding positioning.

• Non-standard punching: Customizable punch pin and die clearance according to special materials in new energy products (such as coated metals, thin-walled aluminum parts) to reduce burrs and deformation.
