Two color injection molding machine It is a kind of equipment widely used in the production of plastic products. It can inject two different colors of plastic materials in the same mold to achieve the colorful effect of products. So, what is the color switching and adjustment process of the two-color injection molding machine? Next, Liansheng Precision injection molding machine Xiaobian will introduce to you

1. Preparation: A series of preparations are required before color switching and adjustment. First, clean the barrel and nozzle of the injection molding machine to ensure that there is no residual plastic material. Then, prepare new color particles to ensure that they are dry and uniform.

2. Raw material switching: First, adjust the nozzle temperature of the injection molding machine to an appropriate range to ensure the melting state of plastic materials. Then, the original color particles can be discharged from the injection molding machine through manual cleaning or automatic nesting system. Next, put the new color particles into the barrel of the injection molding machine and preheat them to reach the appropriate melting temperature.

3. Color adjustment: adjust the color after the injection molding machine is ready. Generally, the two-color injection molding machine is equipped with a special adjustment device, which can control the injection proportion and mixing degree of two color particles by adjusting the nozzle position, temperature, pressure and other parameters. By gradually adjusting these parameters, the desired color effect can be achieved.

4. Testing and optimization: After color adjustment, test injection molding is carried out, and samples are made to check whether the color effect meets the requirements. If further adjustment is required, the parameters can be fine adjusted according to the actual effect of the sample until the desired color effect is achieved.

5. It should be noted that the machine and mold should be kept clean during color switching and adjustment to avoid color cross contamination. In addition, operators need to be familiar with the operating principles and parameter adjustment methods of the two-color injection molding machine to ensure the accuracy and stability of color switching and adjustment.

The above is about the color switching and adjustment process of the two-color injection molding machine. I hope it will be helpful to you.
