Household appliance accessory production injection molding process

Abstract

The invention belongs to the technical field of household appliance accessory production, and particularly relates to a household appliance accessory production injection molding process. The household appliance accessory production injection molding process comprises the following steps that S1, crushing treatment is performed on an ABS material and a polystyrene resin material correspondingly, and grading screening is performed; S2, soaking, stirring and cleaning are performed on the screened raw materials, after floating dust and stains are removed, the raw materials are filtered out; S3, drying is performed on the filtered-out raw materials, wherein the drying time is 20-30 minutes, and the drying temperature is 90 DEG C. Cutting, fine material selection and cleaning modes are adopted to treat the raw materials so that the quality of the raw materials in the material molten state can be effectively improved, meanwhile, impurities mixed in the raw materials are reduced, then the quality of an accessory is further guaranteed after injection molding, so that the accessory is uniform in quality distribution and is flat, in addition, by adopting a double-sided injection molding mode, a layer of polystyrene resin layer is fixed on an outer layer of the accessory made of the ABS material, then the glossiness and the oxidation resistance of the accessory are improved, oxidation discoloration is not prone to occurrence, and therefore the attractiveness is improved.
