What is the preparation work to be done before injection molding production?

As the last step of molding injection parts, we need to carry out a lot of preparatory work before injection molding production to ensure the foolproof production of injection molding.

1. Preparation of plastic materials

1: Confirm the plastic material number/type according to the product drawing requirements;

2: If you need to use the masterbatch or toner, you need to confirm the masterbatch or toner number and mixing ratio;

3: Confirm again whether the material of the barrel is correct;

4: According to the material properties and product requirements, confirm the drying temperature and drying time of plastic materials.

2. Plastic mold preparation

1: Confirm the number of the plastic injection mold;

2: Check whether the plastic injection mold has special structures such as inserts and cores;

3: Plastic injection mold check the positioning ring, hot runner interface and mold appearance is OK;

4: Check the diameter and length of water pipe, pressure plate, bolt length of pressure plate, suspension bridge and other plastic injection mold accessories;

5: Check whether the mold spout and machine nozzle match.

3. Preparation of injection molding machine

1: Confirm whether the plastic injection mold can be correctly installed on the injection molding machine, including the machine Z large clamping force, mold size, mold thickness, pumping function, blowing device, etc.;

2: injection molding machine ejector rod and injection mold is suitable;

3: Check whether the injection screw has been cleaned before this;

4: Check whether the mold temperature machine, manipulator, automatic mixing machine, automatic suction machine can work properly: whether the manipulator fixture matches the mold;

5: Confirm the injection molding production drawings/samples, understand the important dimensions;

6: Prepare other related tools.
