Plastic frosted cup blister forming method

Abstract

The invention relates to the technical field of plastic bottle processing. More specifically, the invention relates to a plastic frosted cup plastic uptake molding method, which comprises: S1, mixing polypropylene, high density polyethylene and frosted master batch to obtain a mixed raw material, uniformly stirring the mixed raw material, adding into an extruder, and carrying out heating melting to obtain a sheet material; s2, the sheet obtained in the step S1 is placed in a heating area of plastic uptake forming equipment and heated to be softened, and a softened sheet is obtained; s3, a mold subjected to texturing treatment in advance is installed in plastic uptake forming equipment, the softened sheet obtained in S2 is added into the mold, and plastic uptake forming is conducted through the plastic uptake forming equipment; and S4, after the blister forming in the S3 is completed, cooling and shaping until the sheet is cured, and opening the mold and removing the cup to obtain the plastic frosted cup. According to the plastic suction molding method for the plastic frosted cup, the frosted effect is achieved in a plastic suction molding mode, and the problems that in the existing industry, frosted cups are high in production cost and low in equipment yield are solved.
