Control of mold temperature and mold temperature on the influence of plastic injection molding process

Control of mold temperature and mold temperature on the influence of plastic injection molding process, mold temperature is the main purpose of a control is to move the mould heated to working temperature, mold temperature constant temperature at work.If the above two points are successful, the cycle time can be optimized to ensure the stable high quality of injection parts.Mold temperature can affect surface quality, fluidity, shrinkage, injection cycle and deformation.Mold temperature too high or insufficient to different materials will bring different effects.For thermoplastic, a higher mold temperature will often improve surface quality and fluidity, but will prolong cooling time and injection cycle.A lower mold temperature will reduce the shrinkage in the mold, but it will increase the shrinkage rate of the injection parts after demoulding.For thermosetting plastics, a higher mold temperature usually reduces the cycle time, which is determined by the time the parts are cooled.In addition, in plastic process.
