Abstract

The invention discloses a material formula and a production technology of a plastic clip. The material formula comprises main raw materials and auxiliary materials, and is characterized in that the main raw materials comprise 75-85 kg of polypropylene and 30-40 kg of polyethylene, and the auxiliary materials comprise 20-30 kg of a toughening agent, 15-20 kg of a thermal stabilizer, 8-13 kg of a low-temperature retention agent, 8-12 kg of an anti-aging agent and 3-6 kg of a lubricant. As the auxiliary materials at different proportions are added into the main raw materials, the high-temperature resistance and the strike resistance of the plastic clip are enhanced.

Description

technical field [0001] The invention relates to a plastic production formula and a production process, in particular to a material formula and a production process of a plastic clip. Background technique [0002] The plastic magazine is filled with 10 nail bullets at a time and then sent into the nail gun. There is no need for manual loading, and continuous shooting can greatly improve productivity. Most of the plastic raw materials of the current plastic clips are polypropylene and polyethylene blended together in a certain proportion, and then the sol temperature, injection pressure, speed, and cooling time are adjusted on the horizontal injection molding machine and then cooled and shaped in the injection mold. income. Various manufacturers of plastic clips have different blending ratios and types of raw materials. Quality also varies. The main deficiency and disadvantage is that the plastic magazine will break during operation, and it is not resistant to high temperat...
