Yang Fan, Wen Shengping (National Engineering Research Center of Novel Equipment for Polymer Precessing, South China University of Technology, Guangzhou 510640, China)
The process of extrusion molding is summarized. It is point out that the requirement for energy-conservation, saving labour, stability in the modern extrusion process increases day by day. In order to guarantee the quality of high-speed extrusion product and economize raw materials, high-accuracy control system is needed. The modern electron and computer control technology is adopted generally in extrusion molding machine in developed countries. The parameters such as melt pressure and temperature in the whole extrusion process are measured online. The computer is adopted for close-loop control. The characteristic and the principle of the control system are analysed. The urgency of the exploctation of new intellectual extrusion equipments is pointed out.
