Automotive Radiator Grille Tooling Mold Design

In the process of forming a plastic mold, various aspects may have a certain impact on it. This impact is good or bad. Good ones can improve its forming quality, while bad ones will cause obvious defects in the plastic mold, leading to Its quality and performance are then reduced, which not only affects subsequent production, but also brings losses to the enterprise.

1.The bonding line phenomenon of plastic mold forming defects

This problem is mainly for special-shaped workpieces. This is a phenomenon where there are obvious traces at the linear turning point. It is caused by plastic molds, such as its low internal temperature, poor lubrication, and improper nozzle position. There are also the effects of filler materials. Excessive hardening and insufficient drying are all influencing factors.


2. Shadows on the surface of plastic mold forming defects

This defect is reflected in the workpiece that does not meet the requirements of color, gloss, etc. Not only will the similar phenomenon occur in the case of plastic molds with small plastic inlets or improper vent positions, but also the material is more volatile or mixed. Foreign matter has the same problem.


3. Silver streak bubbles in plastic mold forming defects

It is also caused by two reasons, one is the plastic mold, and the other is the filling material. Of course, the specific reason must be further analyzed. It may be that the wall thickness of the mold shell is different, or it may be that the material injection speed is accelerated.

4. Poor release from plastic mold forming defects

When the mold temperature is relatively high, the deviation of the main channel hole is large, and the slope of the main channel is small, the material cannot be formed well in the plastic mold, and the problem of bad mold release will follow.


From the above analysis, there are many types and causes of plastic mold forming defects, and there are many similarities in the causes. It can be seen that the impact of the mold on the workpiece is very large. In order to have high-quality product molding, we must learn to use advanced theory and advanced technology to reduce the occurrence of defects.
