Two color injection molding machine Basic operation process of
1. Equipment preparation
Before two-color injection molding, first ensure that the injection molding machine equipment is in normal working condition. Check the electrical system, hydraulic system, mold and other parts of the injection molding machine to ensure that all parts are normal. For the two-color injection molding machine, it is also necessary to confirm the normal operation of the two-color injection system, nozzle and other key parts.
2. Mold installation
The key to two-color injection molding is to select the appropriate mold. Install the two-color injection molding machine mold according to the product design requirements. Ensure that the mold is fixed and positioned correctly to avoid offset or deformation during injection.
3. Plastic color preparation
According to the color design of the product, prepare the plastic particles of the corresponding color. Generally, the selection and preparation of colors are based on the production plan and product design. During color switching, special attention should be paid to cleaning the nozzle and hopper to avoid color mixing.
4. Adjust parameters
According to the specific product requirements, adjust the injection pressure, injection speed, temperature and other parameters of the two-color injection molding machine. Reasonable parameter settings can ensure the molding quality of products and the smooth progress of two-color injection molding.
5. Injection process
Start the two-color injection molding machine for injection process. During the injection process, ensure that the two colors of plastic can fill the mold evenly to avoid color difference or non-uniformity. Monitor the operation status of the injection molding machine, adjust the parameters in time, and ensure the stability of the injection process.
6. Color switching
When you need to switch colors, you can switch colors. First, stop the operation of the injection machine, clean the nozzle and screw, and ensure that the residues of the previous color are fully removed. Then, according to the color switching procedure, gradually inject new color plastic until the new color completely replaces the old color.
7. Check the finished products
After production, take out the injection molded products for inspection. Check the appearance, color, size, etc. of the product to ensure that the product meets the design requirements and quality standards. If defective products are found, timely adjust parameters and molds, and troubleshoot and handle problems.
8. Cleaning and maintenance
After production, clean and maintain the two-color injection molding machine. Clean the mold, nozzle, hopper and other key parts to prevent residues from affecting the next production. Regularly lubricate and maintain the injection molding machine to extend its service life.
Lian Sheng Injection molding machine manufacturer It is recommended that you realize the efficient production of the two-color injection molding machine through the above operation process to ensure product quality and improve production efficiency.
