Double Injection Mold Parts
Double injection mold parts: This is a set of case cover for medical equipment. There are 18 sets of injection molds in the whole project. Only this set is a two-color product. We completed the packaging and shipment of molds for the entire project in 6 months. Solutions to injection molding problems 21. Scratch Marks
Cause:
The bad phenomenon of scratch marks on the injection molded part is mainly due to the fact that the injection molded part interacts with the mold during the demolding process after the injection is completed.
It is caused by excessive friction between the walls and corners of the tool.
Excessive friction of plastic parts is caused by insufficient draft angle of plastic parts, insufficient mold structure strength, and mold damage.
Or the performance of the injection molding machine is related to the adjustment of injection parameters.
Improve methods:
a) Plastic
. Replacement of additive grade materials with high mold release efficiency
b) Mould
. Check the mold clamping line damage
. Increase the smoothness of the upper mold
. Increase the angle of mold ejection
. Check/enhance mold structure and strength
. Check/increase the exhaust duct of the upper mold
. Check the smoothness of the cooling pipe/calibration rate
. Increase the upper mold cooling pipe
c) Injection molding machine conditions
. Optimize the holding pressure conversion position
. Reduce holding pressure
. Reduce injection speed
. Reduce pressure holding time
. Reduce injection temperature
. Reduce mold temperature
. Reduce the speed at the first stage of mold opening. Customers who want to make double injection mold parts, please email: qxwmould_co_ltd@163.com
