Bimetallic products using polymer materials,especially the typical plastic,as an important alternative materials,applications in everyday life as well as in various industrial increasingly wide variety of modified plastics by more and more.Often added to the plastic e.g.calcium carbonate,kaolin,red clay,modified silica,or glass fiber,carbon fiber,boron fiber,etc.to be reinforced.Because of these fillers,reinforcing agents to join,on the one hand and plastic properties can be changed for the manufacture of certain products,on the other hand is exacerbated by the plastic processing machinery,especially plastic extruder or injection machine heart parts-Screw Barrel wear and corrosion,and replace these parts or downtime makes manufacturers must spend a lot of financial,material and down time,production efficiency significantly affected.
The company developed high wear resistance,corrosion resistance bimetallic barrel and melt bimetallic screw technology to further develop in depth,and its production of bimetallic products help thousands of users greatly extend the heart of plastic processing machinery parts life.Leading technology bimetallic extrusion components applicable general resins and a high proportion of high-function resin & glass fiber,carbon fiber,and a variety of additives,fire,electric and wood PPA,PPO,PPS,LCP powder,PC and other special engineering plastics.We customized turnkey solutions for you.
