Carbon Tungsten Alloy Screw for Extruder

By combining the technology of Stellite company in Germany, our company has developed tungsten carbide alloy powder
at different levels on the basis of original alloy products, which is sprayed on the screw surface by using the most advanced high
temperature, high pressure and high speed plasma spray technology and casted on the inner wall of charging barrel by the high
temperature furnace and centrifugal casting technology to produce high-density, super wear-resistant and corrosion-resistant alloy
charging barrels to extend their service life and meet the customers' requirements for reducing usage cost.
Alloy grade: Grade A-tungsten carbide content: 40%~50%
Grade B-tungsten carbide content: 25%~30%
Grade C-tungsten carbide content: 9.5%; (only suitable for PTA)
Alloy composition: Wc+Wo+Cr+Ni+selffluxing alloy powder
Alloy thickness: 2.0mm~3.0mm
Alloy rigidity:HRC60°~70°
Production range: minφ18mm~maxφ300mm;
Useful length: 5000mm;
Applicable equipment: injection molding machine, extruder, etc. Scope of
application: used for adding CF (carbon fiber) and GF (glass fiber) like PA,PP,PS,PA66,POM,
PBT,PPS,LCP,PPO, etc. electric wood, magnetic powder, iron powder, etc. to special engineering
plastics

 Air To Air Waste Heat Recovery Equipment

Waste heat recovery equipment is a kind of metal plate heat exchanger, where the air pass

through and exchange energy(heat-recovering system and exhaust heat recovery system). It can separate fresh air and exhaust air completely, avoided

any solvent transmission. The two air cross and counter flow to the exchanger, then fresh

air and exhaust air exchange energy through the metal plate,

collisions between particles in the hot inner region transfer energy to particle

s in the cooler outer region and realize to recycle energy from exhaust air.
