extrusion quality
4.In recent years, with the the rapid development of CAE, people could simulate the flowing of the plastics melt in the extrusion die and forecast some relationship in the geometry parameter, processing conditions and product quality which could advance the designing efficiency and level by integrating some experience.
6.This paper relatively systematically introduces the original basic principles, construction craft, specialized equipment, quality inspection method, domestic application situation and prospects of construction technique on extrusion side wall of concrete face rockfill dam; shows the wide application prospects of construction technique on extrusion side wall.
7.With the combination of theoretical analysis and experiment,the mechanism of wall slip in an extrusion die of polymer melts was discussed in this paper. It provided theoretical basis for the die designing and the controlling of technical parameters reasonably,as well as getting products of high quality.
8.Companies with the "Quality First, the user first" for the purpose of use in a variety of aviation, the MTR, motor vehicles and air-conditioning compressors, textile machinery, machine parts and bicycles, and other products supporting non-ferrous metal forgings, cold extrusion parts, heat treatment items such as non-ferrous metal products.
