Abstract
The invention discloses a plastic bracket for an automobile and a manufacturing method thereof. The manufacturing method of the plastic bracket for the automobile mainly comprises the following steps of: adding dried and proportioned raw materials into a heated injection molding machine; and obtaining a final qualified product by setting injection pressure, speeds, injection time and injection glue amounts of the injection molding machine in different sections, and setting final holding pressure and a holding speed to reach an optimal injection molding process. The defects in physical performances of the product, such as transformation, fracture and bad toughness, are overcome when the plastic bracket of the automobile is molded through injection molding. Meanwhile, the injection molding process is stable, the quality of the obtained product is stable, the production efficiency is improved and the production cost is reduced.
