Embodiment 1

[0028] figure 1 It is a flow chart of a plastic product secondary molding treatment method provided in the embodiment of the present application, and the method includes:

[0029] Step 101: heating the obtained once-molded plastic product;

[0030] The embodiment of the present application provides a secondary molding processing method for plastic products. Before performing secondary molding on the plastic product, firstly obtain a plastic product of primary molding, which can be obtained by injection molding or blow molding in the prior art. of plastic products. Such as figure 2 Shown is a schematic diagram of a one-time molded plastic product provided by the embodiment of the present application. The length of the one-time molded plastic product 1 is 215 mm, and the gap between the upper and lower buckle covers is 2 mm.

[0031] The purpose of heating the obtained once-molded plastic product 1 is to soften the once-molded plastic product 1 so that it can be molded again...

Embodiment 2

[0045] Figure 5 Another flow chart of a plastic product secondary molding processing method provided in the embodiment of the present application, the method includes:

[0046] Step 201: Obtain a plastic product molded at one time;

[0047] In yet another secondary molding treatment method for plastic products provided in the embodiment of the present application, before performing secondary molding on the plastic product, firstly obtain a plastic product that is once molded, which can be obtained by injection molding or blow molding in the prior art A molded plastic product.

[0048] Step 202: covering the surface of the once-molded plastic product with a heat-shrinkable film;

[0049] Specifically, covering the heat-shrinkable film can fix, cover and protect the plastic product.

[0050] Step 203: heating the once-molded plastic product covered with the heat-shrinkable film;

[0051] Specifically, heating the once-molded plastic product can soften the once-molded plastic ...

Abstract

The invention belongs to the technical field of plastic forming, particularly relates to a secondary forming processing method of a plastic product. The secondary forming processing method comprises the following steps of heating an obtained primary-formed plastic product; putting the heated primary-formed plastic product in a jig for fixing; and fixing the primary-formed plastic product for a certain time, so as to obtain a secondary-formed plastic product. Through the adoption of the technical scheme of the secondary forming processing method disclosed by the invention, the problems that in the prior art, the plastic product is warped, twisted, uneven and the like are solved, and the secondary forming processing method has the technical effect of overcoming the deforming defects of the plastic products.

Description

technical field [0001] The invention belongs to the technical field of plastic molding, and in particular relates to a secondary molding treatment method for plastic products. Background technique [0002] Plastic products are indispensable daily necessities and industrial supplies for modern human life. At present, most of the plastic products on the market are made by injection molding, blow molding and other processes. In the molding method of plastic products in the prior art, plastic raw particles are heated and melted and then injected into molding. In the process, affected by various factors such as product wall thickness and size, the shrinkage rate will be uneven, and the final product will have warping. Curved, twisted, uneven and other problems. Contents of the invention [0003] The embodiment of the present application provides a secondary molding treatment method for plastic products, which improves the problems of warping, twisting, and unevenness of plast...
