The surface of the product is bright, then do you know what high-light injection molding technology is?

How to produce shell products with no melting marks, no flow marks, no streamlines, no sink marks, and high surface gloss is particularly important for flat panel TVs, computer LCD monitors, air conditioners, and automotive interior parts. Using high gloss Injection Molding technology can solve this problem well.
The principle of high-light injection molding is:
The mold is heated before the mold is closed and the mold is closed. After the mold is closed, the temperature reaches the set condition and injection is performed. During the injection process, the mold continues to maintain a high temperature, so that the glue can maintain good fluidity in the mold during injection. After the injection is completed, the temperature of the mold is cooled when the pressure is maintained, and the cooling time of the product can be greatly shortened, thereby improving the production efficiency.
Steam-free high-gloss injection molding technology currently belongs to an advanced production process in China. As this technology greatly improves the surface quality and surface strength of the products, it can eliminate the subsequent spraying or painting processes, protects the environment and the human health of the operators, and reduces the cost of the process due to the reduction of the process flow. Processing costs save energy and materials while significantly reducing production costs.

The traditional method is to use a mold temperature machine to warm the mold, but the shortcomings of this method are as follows:
1) Unable to meet the need for rapid temperature increase and rapid temperature reduction in high-gloss injection molding;
2) The heating rate is small, and the weld marks on the surface of the product can only be reduced and cannot be eliminated;
3) The higher the hardness of the plastic, the worse the flowability. Therefore, the hardness of the surface of such products can only reach the HB level and can not meet the actual needs;
4) When the mold is heated up, it will expand by heat, and when it cools down,
