Molded parts sticking in mold cavity
We are currently facing a problem with parts frequently sticking in the mold cavity…shape of the part is like that of a battery cover….Does anyone have any other suggestion??
Check mold for undercuts and/or insufficient draft.
Decrease booster time.
Decrease cylinder and nozzle temperature.
Decrease injection pressure.
Decrease mold cavity temperature.
Increase clamp pressure.
Increase mold-close time.
Texturing on part is too deep. The parts may stick in the cavity if a new texture or a retexturing has been performed on the cavity half of the mold.
If possible add undercuts to the core to allow the part to pull out of the cavity.
Sufficient cooling for all the areas.
Achieve a Good Surface finish.
