Factors affecting mold life and methods to improve mold life

The mold life restricts the application and development of fine blanking technology. Therefore, we must pay attention to the service life of the mold. The following editor will provide you with the factors that affect the mold life and tell you the ways to improve the mold life.
Factors affecting mold life
1. Structural manufacturability of fine blanking parts (sharp corners, thin walls, suspended walls, dimensional tolerances, etc.).
2. Materials of fine blanking parts (material quality, material thickness, hardness, plasticity, surface quality).
3. […]

What will happen if the polishing time is too long during mold processing

As we all know, plastic mold is an indispensable supporting product in the plastic processing industry. There is also a plastic molding machine, which can make the mold structure better, higher precision and high integrity. However, because the processing methods and materials of plastic mold will be different, the type and structure of the mold will not be the same.
In the process of plastic mold, because its polishing steps must also be experienced, but if it is not handled […]

What should we pay attention to when checking and accepting plastic molds made by manufacturers

When looking for a special mold processing manufacturer to customize plastic molds, in addition to communicating and confirming with the manufacturer about the details of the customized molds before production, enterprises should also pay attention to the relevant acceptance work after the completion of the whole mold processing. Only when the plastic mold made fits the mold you want to make better, can it provide more help for the subsequent actual production.
In the acceptance of the finished plastic model, […]

What is the structure of the injection mold?

The plastic mold is composed of a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the gating system and cavity. When opening the mold, the moving mold and the fixed mold are separated to take out the plastic […]

What if the injection molded products are burnt during injection molding?

Scorch marks refer to the phenomenon of blackening at the end of the flow because the gas in the mold cavity cannot be discharged in time.
Causes of coke marks:
1. The cavity air cannot be discharged in time
2. Material degradation
a. Excessive melt temperature
b. Too fast screw speed
c. Improper design of runner system
Improvement method:
1. Mold design
a. Add an exhaust system where poor exhaust is easy to occur
b. Increase the size of sprue, shunt and gate
2. Process conditions
a. Reduce injection pressure
b. Reduce […]
