Three-color mixed particle composite material and molding method of suitcase shell

Abstract

The invention discloses a three-color mixed particle composite material, which comprises at least one PVC color master batch, an ABS color master batch with a color different from that of the PVC color master batch, and a light-resistant color master batch. The invention discloses a forming method for manufacturing a suitcase shell from the three-color mixed particle composite material, wherein the forming method comprises the following steps: S1, raw material mixing; S2, raw material adding; S3, mold preparation; S4, checking of die-casting equipment; and S5, die casting. According to the invention, by changing the components of the three different-color master batches, after the three different-color master batches are molten at a set temperature, the situation of excessive uniform mixing is avoided, and the effect of drawing between colors can be achieved in the subsequent box shell forming and manufacturing process, so that the sensory effect is good, the overall function is complete, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of suitcase manufacturing, more specifically, it relates to a three-color mixed particle composite material and a molding method for a suitcase shell. Background technique [0002] Existing suitcases have multiple colors and a single color, which cannot achieve the multi-color effect after completion, and there is a drawing effect between colors, which cannot be reflected. The main reason is that the materials are concentrated together after being mixed and melted at high temperature. The color does not work as expected; [0003] And the box body of existing suitcase all adopts plastic-absorbing process to form the flat plate into a groove-shaped box body, and after forming, the redundant material of the box body port of the groove-shaped box body is cut off and polished into shape, which leads to the loss of corner material The waste, the cost increase, the production process is long, and the hardness of t...
