ADVANTAGE

Strength and durability: Products manufactured by the one-piece tensile process have no welds, thus avoiding the heat-affected zone that can be created during welding, which typically reduces the strength of the material. In contrast, products that are drawn in one body have more advantages in overall strength and greater durability. It is also more resistant to external impact, collision and extrusion, protecting the battery pack from damage.

Tightness and water resistance: The weld in the welding process is a potential leak point, while the one-piece drawing process completely avoids this problem. The integrated stretching product has no joint, so it has better sealing and water resistance, and more effectively prevents moisture, dust and other external substances from entering the battery pack to ensure the stable operation of the battery pack.

Beauty: The welding process may produce uneven welds, uneven widths, large deformation and other phenomena, affecting the beauty of the product. The surface of the product manufactured by the integrated drawing process is smooth and flat, without subsequent polishing treatment, and the appearance is higher.
