Description

A kind of IMD in-mold injection shoe material auxiliary material production process

technical field

The invention relates to the field of injection molding technology, in particular to a production process of shoe material auxiliary materials by IMD in-mold injection molding.

Background technique

The production of shoe materials and accessories is a very important part in the process of processing shoes. The traditional shoe materials and accessories are produced by injection molding TPU, but the shoe materials and accessories produced in this way are prone to yellowing and discoloration, not scratch-resistant, and glossy. The temperature is poor, and it is easy to deform and break when encountering high temperature and low temperature.

Therefore, those skilled in the art provide an IMD in-mold injection molding shoe material auxiliary material production process to solve the problems raised in the above-mentioned background art.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an IMD in-mold injection molding shoe material auxiliary material production process, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A production process of IMD in-mold injection shoe material accessories, the production process comprises the following process steps:

1. Selection of plastic film, through the selection of high-quality film plastics, the quality assurance of raw materials can be achieved;

2. Rubber film printing; printing plastic film:

1. Rank the plastic film, confirm the size, and make the printing screen;

2. After the screen plate is made, the pattern is printed;

3. Mold design, design the required molds;

4. Plastic film forming; use mold to form plastic film;

5. Shape punching; punching the formed sheet according to the required size;

Sixth, implant into the mold; put the punched sheet into the mold;

7. Die location; size, shape, and hole processing of the sheet;

8. Forming and injection; moving the formed sheet out of the mold;

9. Material selection; brush the processed sheets;

Ten, production of finished products: processed into the required finished products.

As a further solution of the present invention: in the first step, it is necessary to check the plastic film for dust spots and scratches, and to check whether the electroplating gloss is uneven.

Compared with the prior art, the beneficial effects of the present invention are:

1. Reform the traditional production process, apply the IMD process to the production of shoe material accessories, print various patterns and characters on the sheet, and then send the laminated sheet to the injection molding machine for in-mold lamination. Film injection molding, the pattern of shoe material accessories produced by this production process has good wear resistance, full and bright colors, strong three-dimensional effect, and is not easy to change color and yellow, high temperature and low temperature resistance, bending resistance, and it is more suitable for shoe materials. It shows unprecedented practicality, which is a powerful complement to the processing technology of this industry.

2. The whole process basically produces no pollution and meets the requirements of environmental protection.
