The two-color mold is made of two plastic materials on the same machine and can only be molded in two parts. However, the product is usually just a one-time mold, and this process is also called bi-material injection molding.

The two-color injection molding industry in my country is developing rapidly and is currently popular in the market. The two-color injection molding process can make the appearance of the product more beautiful, easy to change the color without spraying, but it is expensive and requires high technical requirements.

The selection of injection mold materials and the maintenance of injection molds are a very important link. Choosing a good injection mold material can reduce damage to the quality of plastic parts, and the maintenance of injection molds can increase the use time of injection molds. The following is Let's take a look.

The appearance of two-color injection molding products, the physical properties of the material, and the molding cycle are significantly affected by the mold core temperature. Therefore, the temperature control during the two-color injection molding process is very important.

The two most important processes for two-color injection molding and two-color injection molding are filling and pressure holding. Next, Heng zhao will tell you how to control pressure in two-color injection molding.
