Injection molding test mold process steps

1. Design trial mold plan

After the plastic mold product design is completed, a trial mold design needs to be carried out. According to the product requirements, process capabilities and injection molding machine requirements, the structure and design plan of the trial mold are determined.

2. Preparation of trial mold materials

According to the trial mold structure and production requirements, prepare trial mold materials to ensure that the material quality meets the requirements.

3. Clean the injection molding machine

Before trying out the mold, the injection molding machine needs to be cleaned to avoid adverse effects on the product.

4. Assemble trial mold

According to the design plan, the trial mold is assembled on the injection molding machine to ensure the accuracy and stability of the trial mold.

5. Debugging process parameters

According to the trial mold structure and product requirements, the process parameters of the injection molding machine are debugged, such as injection speed, injection pressure, mold temperature, etc.

6. Trial mold operation

Before the mold trial, the injection molding machine needs to be preheated to ensure that the temperature of the trial mold is stable, and then the mold trial operation is performed to adjust parameters such as the nozzle, melt temperature, and injection pressure.

7. Injection molding production verification

Conduct injection molding production verification to verify the stability of the injection molding machine and product quality to ensure that the product meets the requirements.

Precautions for injection mold trial

1. Clean the injection molding machine before mold trial

Before the mold trial, the injection molding machine needs to be cleaned to ensure that the injection molding machine is clean and hygienic before the mold trial.

2. Design a reasonable mold trial plan

Before the mold trial, a trial mold design needs to be carried out. According to the product requirements and the requirements of the injection molding machine, a reasonable trial mold plan should be designed to ensure that the structure and performance of the trial mold meet the requirements.

3. Trial mold material selection

Choosing the appropriate trial mold material must not only meet the quality requirements of the trial mold, but also consider the cost and service life of the trial mold.

4. Debugging of injection molding machine process parameters

During the mold trial process, it is very important to debug the process parameters of the injection molding machine. It needs to be debugged according to the product requirements and trial mold structure to ensure reasonable process parameters and make the product meet quality standards.

5. Good at recording the mold trial process

During the mold trial process, you need to be good at recording the mold trial operations and verification process, and deal with problems in a timely manner to ensure production stability and product quality.

Injection mold trial is a very important link in the injection molding production process. It is necessary to pay attention to the debugging of the injection molding machine and trial mold design to ensure that the trial mold process goes smoothly and products that meet the requirements are produced.
