22. What to do when the prototype injection molded product is bent?

When the Prototype injection molded product is bent, the situation is as follows:

• The mold is too hot or not cooled enough.

• When the mold core is used, it should be checked and calibrated.

23. What happens to prototype injection molding when the product is cracked and bleached?

• When the melt and mold temperature is too low.To increase the temperature of the cylinder and the mold.
• When the structure design of the mold gating system is unreasonable. Improve the flow channel and gate structure of the crystallizer so that turbulence will not occur when the melt is filled into the crystallizer.
• When the cooling time is too short. The cooling time should be extended appropriately.
• For improper ejector design, pneumatic demolding device is preferred.
• When the injection speed and pressure are too high, it should be reduced appropriately.
