1.bimetallic screw and barrels of high quality
2.bimetallic screw and barrels of long operating life
3.ISO 9001:2008 approved
a bimetallic barrel is casted on the inwall with a 2-3mm alloy lay-out,which is wear-resisting\anti-corrosiveand anti-high-temperature.Its effective life has been highly improved compared with ordinary nitriding barrel.The bimetallic barrel is with particular speriority in processing engineering plastics\fluorinated plastic\polysulfone\PPO and other special plastic.Bimetallic alloy and welding method shall be varified according to all kinds of functional
screws and barrels.
Screw diameter:Φ15mm-Φ360mmL/D=15-56
