Three issues that need to be paid attention to in two-color injection molding

As we all know, two-color injection molding is a very precise process, involving knowledge of multiple disciplines such as physics and chemistry. Below, we will briefly introduce the three precautions for two-color injection molding, hoping to be helpful to everyone.

1. For different materials, the temperature required during injection molding is also different. If the temperature is too high or too low, it will have an unfavorable effect on the processing of the material, and it will have an adverse effect on the finished product after all. For example, when the temperature is too low, there will be some abnormalities in the color of the liquid material; when the temperature is too high, the product will have the appearance of burrs after it is produced, and the quality of the product will not meet the demand. 

2. In the two-color injection molding process, you need to pay attention to control the speed in the pouring channel. If it is too immediately, there will be burrs, and it will also cause overfilling and burning. If it is too slow, there will be signs of shrinkage and simple cracking. Therefore, you must pay attention to the control of its processing speed when pouring, so that the quality of the products produced can meet the requirements.

3. In the two-color injection molding process, you need to pay attention to controlling the cooling time. The detailed required time also needs to be determined according to the details of the processed product. The cooling time has a greater impact on the processing of the injection mold on the brightness of the finished product, so more attention must be paid.
