Lower mold temperatures can shorten the cooling time, but maybe because the temperature dropped rapidly, but increasing hinder filling plastic into the mold. These phenomena led to the existence of high stress. When temperature increases mold shrinkage make full shape, reducing shrinkage later. At the same time reduce the intrinsic stress and increase product surface quality.
Unable to shorten cooling by reducing the temperature of the mold that had interest from product design mold design
principle is implemented tracking device operating temperature mold temperature is maintained at a fixed oscillator. First, the injection molding cycle, the mold temperature will increase from 5ºC ÷ 15ºC by contact with liquid plastic During the starting phase, the mold temperature will increase over a period determined to reach the temperature status stable to heat exchanger. This temperature can be from 10 ° C to 30 ° C higher than the initial temperature of the system and also to control the temperature fluctuations during production?
