Injection molding is a processing method used when mass-producing some parts with complex shapes. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, the formed product is obtained.

[0003] For some products of battery brackets, such as Figure 1 As shown, fixing parts extending outwards are arranged on both sides of the bracket body. A "C"-shaped structure is formed between the bracket body and the fixing parts on both sides, and multiple groups of circular grooves for clamping batteries are arranged in the fixing parts.
