Problems solved by technology

[0002] Due to the small thickness and large area of ​​the plastic, during the foaming process, the internal temperature is 170° when the mold is closed, and there is a pressure of 1000Mpa to 1100Mpa, and it expands at the moment of opening the mold. Due to the longitudinal resistance, the final formed There will be waves on the plastic products, making the lines not clear enough, which will make the pass rate of the products low

Embodiment 1

[0011] The manufacturing method of the present embodiment plastic comprises the following steps:

[0012] (1) Making semi-finished products: Put the mesh cloth coated with slurry into the foaming mold, spread it flat, and then foam at 170°C for 12 minutes to shape the material, then cool to room temperature, and take out the semi-finished product from the mold;

[0013] (2) Cutting semi-finished products: testing the hardness of semi-finished products, cutting semi-finished products with a hardness of 32HA according to the size of the final product;

[0014] (3) Secondary processing: Put the semi-finished products cut into small pieces into the hot-pressed cooling and shaping integrated mold for embossing treatment, close the mold, pass steam into the circulation cavity, heat the mold to 120°C, keep 3min; then turn off the steam, enter cold water to cool until the plastic product cools to room temperature, and take the product out of the mold.

Abstract

The invention relates to a plastic manufacturing method. The plastic manufacturing method comprises the following steps: putting a mesh coated with slurry into a foaming mold, spreading, and taking asemi-finished product out of the mold; and detecting the hardness of the semi-finished product to ensure that hardness of the semi-finished product reaches between 28HA and 32HA, and then cutting thesemi-finished product of which the hardness meets the demand into sections according to the size of a final product. The plastic manufacturing method provided by the invention has the advantages thatthe grain of plastic manufactured through the plastic manufacturing method is clearer, and the product qualification ratio can reach 99%.

Description

technical field [0001] The invention relates to plastics, in particular to a method for making plastics. Background technique [0002] Due to the small thickness and large area of ​​the plastic, during the foaming process, the internal temperature is 170° when the mold is closed, and there is a pressure of 1000Mpa to 1100Mpa, and it expands at the moment of opening the mold. Due to the longitudinal resistance, the final formed There will be waves on the plastic products, which will make the lines not clear enough, which will lead to a low pass rate of the products. [0003] Therefore, it is very necessary to develop a plastic production method that can make the plastic texture clearer and the product qualification rate higher. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a method for making plastic. [0005] In order to solve the above-mentioned technical problems, the technical solution of the present invention is:...
