Production process of plastic leather-coated spectacle case

Abstract

The invention relates to a production process of a plastic leather-coated spectacle case, which particularly comprises the following process steps: performing injection molding of ABS engineering plastics by a mold and an injection machine to obtain inner casings of an upper cover and a lower cover, cutting a fabric layer of artificial leather for coating the inner casings of the upper and the lower covers; uniformly coating a neoprene adhesive on the external surfaces of the inner casings of the upper and the lower covers and the interior surface of the fabric layer, performing heating, pressurization and pasting of the adhesive-coated fabric layer and the inner casings of the upper and the lower covers by a leather coating machine to obtain the upper and the lower covers after pasting; connecting the upper and the lower covers together by a hinge, pasting a flocking inner liner on the interior surfaces of the inner casings of the upper and the lower covers respectively to obtain a spectacle case finished product. The invention solves the technical problem of the unfirm bonding between artificial leather and the plastic surface, and the produced spectacle case is springy, has enhanced anti-impact force, is not easy to be damaged, is portable, and has a long service life.

Description

technical field [0001] The invention relates to a spectacle case, in particular to a production process of a plastic-covered spectacle case. Background technique [0002] Existing glasses case basically is divided into two kinds of structures, and a kind of is all-plastic glasses case, and another kind is iron plate foreskin glasses case. The all-plastic glasses case adopts one-time injection molding, and one side of the upper and lower covers is connected by soft plastic. This spectacle case has poor impact resistance, is easily damaged, and has a short service life. The iron-covered glasses case is stamped with a thin iron plate to make the upper and lower cover inner shells. The lower covers are hinged together, and the inner surfaces of the inner shells of the upper and lower covers are respectively pasted with flocking inner linings to complete the finished glasses case. This kind of spectacle case is heavy, which increases the transportation cost during the product ...

AI Technical Summary

Problems solved by technology

This kind of glasses case is heavy, which increases the transportation cost during the product sales process. In addition, the bonding firmness of the fabric layer is not ideal, and there is a phenomenon of glue opening.

Moreover, my country only needs to consume 10,000 tons of thin iron plates for the production of iron-covered glasses cases each year, which consumes a lot of resources.
