Part Sticking.

Part is getting not pulling out of the cavity and in rarer circumstances cannot be ejected off the core. Possible Solutions Check mold for undercuts and/or insufficient draft. Decrease booster time. Decrease cylinder and nozzle temperature. Decrease injection pressure. Decrease injection-hold. 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.
