Abstract

The invention discloses a TPU polyurethane and mucous membrane combined finished product production method, relates to the technical field of lettering membrane manufacturing, and solves the problem that modulated colors cannot be directly printed on a TPU injection mold. The method specifically comprises the following steps: confirming finished product material information, and drawing a product pattern; manufacturing a forming mold according to the pattern; preparing a mucous membrane according to raw material information, and performing laser marking, die cutting and high-frequency die cutting; carrying out TPU polyurethane back glue combination on the manufactured adhesive film and a forming mold by utilizing hot melting; and after removing the residual colloid on the product, drying and shaping the product to obtain a final finished product. The finished product material information comprises color, pattern, size and thickness requirements of product manufacturing. A lettering film and the forming mold are subjected to TPU polyurethane gum combination through the hot melting technology, mold printing is not directly used, and the problem that some cold tones cannot be printed on TPU injection molding is solved through combination of the lettering film and the forming mold.

Description

technical field [0001] The invention relates to the technical field of lettering film production, in particular to a method for producing a finished product in which TPU polyurethane and mucous film are combined. Background technique [0002] TPU polyurethane is a kind of thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, commonly known as injection molding. Thermoplastic polyurethane elastomer is a kind of elastomer that can be plasticized by heating and can be dissolved by solvent. It has good processing performance and is widely used in shoe materials, cables and clothing. , automotive, medical and health, pipe, film and sheet and many other fields, suitable for medium and small size parts produced in large quantities. The mucous film is a kind of lettering film with hot melt adhesive on the back, also known as transfer film. The lettering film refers to the heat transfer film that needs to be cut / engraved during the heat transfer proce...
