composite extrusion
解釋
復合擠塑-
Liquid - solid extrusion of composite material is a new kind of metal forming process, which has been developed in recent years with a promising practical application prospect for its simple working procedure, low cost and good workpiece performance. through a lot of experiments, the optimization and chosing method of key process parameters ( pouring temperature, mold warm - up temperature, impregnating pressure, impregnating time ) has been mastered. under the precondition of appropriate chosing these parameters, the effective control of extrusion velocity is the key of mading good workpiece. but the control of extrusion velocity remains a handwork, and it is heavily affected by such uncertainties as a handler ' s knowledge and skill about the process. in order to solve the problem, the automatic control of the extrusion velocity is studied, and a computer control system is also designed under existing condition
