Home > Universal Screw >> Planet Screw Barrel

Planetary screw using the material:
Domestic material,38CrMoAlA,SACM645,42CrMo,
Use Switzerland-ShengBai company's top quality powder alloy steel-ASP60,ASP30,ASP25,through the whole vacuum quenching,tempering process two times,is especially suitable for high wear,high corrosion products processing requirements.
Use Japan high speed tool steel:SKH51,SKH55,SKH59 etc,especially suitable for high wear products.Planetary roller extruder consists of a central spindle,a planet shaft,rolling barrel,outer shell,heating and cooling and the nozzle.Structure of the module system,has good flexibility.The contact area is the previous single shaft and two-axis extruder five times,and the section shape of molten material in favor of the highly dispersed and uniformly,so it can get high quality products.
And it's mainly used for heat sensitive materials,hard and soft PVC calender with discharging.Can also be used for the extrusion of ABS,TPO,TPU and filled polyolefin smoke and binder mixture.Now in the powder coating industry achievements.Chemical and food industry is also expanding application.Having good raincoats,plastic film materials,salt film,home textiles packaging.plasticizing effect,self-cleaning performance,high output,long span life etc.
