- Mold temperature is the most important parameter affecting shaping cycle and product quality. 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.
? - Cooling time is determined primarily based on the temperature of the mold. Unable to shorten cooling by reducing the temperature of the mold that must concern the design stage of the product (to avoid unnecessary thickness), mold design (mold material, plastic channels, cooling water lines ... )?
-To meet the product characteristics, especially the shaping, the need to identify the mold temperature reached. The 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. In the next cycle, this increases the amount of heat needs to be reduced by heat load away. ?
