JWELL adopts new generation technology HP/HVOF totally bimetallic coating spraying instead of PTA ridge spraying welding. WPT1 anti-corrosion type application: nylon, PVC,PC,PMMA etc. WPT2 resistant wearing and high tempera ture application: nylon with glass fiber magnetic powder, Al Mg powder, Bakelite injection and etc. WPT3 has WPT1 and WPT2 advantages.
In the case of bimetallic barrel for melt, the carbon tungsten containing has been rasied from the previours 10% to 30% and 50% now, the processing length increased from 3000mm to 4000mm.
