It is mainly involved in the basic molding principle, position, chief tech parameter, general parts and relevant coordination system, assist equipment, and how to operate safely and maintain , as well ashow to obviate the error, surly the connection and mutual impact among these item. Furthermore, on the basis of working principle , structure , and relevant subjects, this thesis gives a deeper analysis, both theoretical ly and practically, and a benign promotion to the traditional types. It does study on the problem of principals, structure, plastic-molding process in synthesis, separate the main contradiction and optimize the plan in order to benefit the highest profit and social interest.
