Injection molding production is the last step of molding injection molded parts. Before injection molding processing and production, we need to do a lot of preparatory work to ensure that injection molding processing and production are foolproof.
1、 Preparation of plastic materials
1. Confirm the number / type of plastic materials according to the requirements of product drawings;
2. If you need to use color masterbatch or toner, you need to confirm the number and mixing proportion of Color Masterbatch or toner;
3. Reconfirm whether the materials in the barrel are correct;
4. Determine the drying temperature and time of plastic materials according to the material properties and product requirements.
2、 Plastic mold preparation
1. Confirm the number of plastic injection mold;
2. Check whether the plastic injection mold has special structures such as inserts and core pulling;
3. Check whether the positioning ring, hot runner interface and the appearance of the plastic injection mold are OK;
4. Check the diameter and length of water pipe, the length of pressing plate, pressing plate bolt, suspension bridge and other plastic injection mold accessories;
5. Check whether the mold pump nozzle matches the machine nozzle.
3、 Preparation of injection molding machine workbench
1. Confirm whether the plastic injection mold can be correctly installed on the injection molding machine, including the maximum mold locking force of the machine, mold size, mold thickness, core pulling function, air blowing device, etc;
2. Whether the ejector rod and injection mold of the injection molding machine are suitable;
3. Check whether the injection screw is cleaned before injection;
4. Check whether the mold temperature machine, manipulator, automatic mixer and automatic suction machine can work normally: whether the fixture of the manipulator matches the mold;
5. Confirm the drawings / samples of injection molding products and understand the important dimensions;
6. Preparation of other relevant tools.
