Manufacturing method for ultrathin embossment protective case

Abstract

The invention discloses a manufacturing method for an ultrathin embossment protective case. The manufacturing method comprises the following steps of 1) preparing a vacuum-thermoforming material; 2) thermoforming the vacuum-thermoforming material to form a plate material with a plurality of recesses matching with profiles of to-be-protected products uniformly distributed on the surface of the plate material; 3) punching the plate material to form a plurality of semi-finished product shells matching with the profiles of the to-be-protected products; 4) performing trimming and shaping treatment on the semi-finished product shells; 5) flap-molding the semi-finished product shells; and 6) carrying out hot-press punching treatment on the semi-finished product shells to obtain the ultrathin embossment protective case. By using the principle of the thermoforming technology and improving every process, technology and machinery equipment, the ultrathin embossment protective case can be manufactured efficiently and accurately; the problems of temperature resistance and pull-up property of conventional different materials can be well solved; the ultrathin embossment protective case has excellent high temperature thermoforming performance and relatively low cost; and the composite material is suitable for preparation of full-automatic composite machines.

Description

technical field [0001] The invention relates to the technical field of plastic absorption and mold making, and provides a method for manufacturing an ultra-thin embossed protective shell. Background technique [0002] For a long time, injection molding and blow molding have been the main processing methods in the field of plastic processing, especially the production of mobile phone protective cases generally uses plastic injection molding or metal stamping molding. The disadvantages of this type of process are: the development cycle of the mold is long, the cost of mold opening is high, the product cannot change the surface relief effect in a short period of time and at low cost, and it is difficult to realize the production of ultra-thin relief leather case / protective shell. [0003] An important part of the thermoplastic forming process is the vacuum blister forming process. However, at present, the blister material compounded in the blister material fails due to the com...

Problems solved by technology

The disadvantages of this type of process are: the development cycle of the mold is long, the cost of mold opening is high, the product cannot change the surface relief effect in a short period of time and at low cost, and it is difficult to realize the production of ultra-thin relief leather case / protective shell

However, at present, the blister materials made of compounded plastic materials fail to absorb due to the compounding problem of the material itself, and it is difficult to achieve accurate manufacturing in the past follow-up process of blister forming.
