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.

Description

Background technique [0001] The invention relates to a plastic bracket for automobiles and a manufacturing method thereof, belonging to the field of automobile parts materials. Background technique [0002] With the progress of society, the demand for automobiles does not increase. However, automobiles consume a large amount of fuel and emit a large amount of pollutants, causing serious pollution to the atmospheric environment. The fuel consumption of automobiles is closely related to the quality of automobiles. According to reports, automobiles themselves For every 100KG reduction in mass, 0.2-0.3L / 100Km of fuel can be saved. At present, the proportion of plastics in the total materials used in automobiles is still relatively low. With the emphasis on the weight reduction of automobiles themselves, the proportion of plastics will increase to about 31%. [0003] At present, the brackets of automobiles mainly adopt steel plate stamping and welding brackets, cast iron cast st...
