Its an extruder, both the cylinder and screw rods are made of high quality alloy steel, 
that have been azotized and processed in a precision way. Hence it is sound in hardness, 
durable in corrosion resistance. The specially-designed screw is sound quality in 
plasticizing, which helps increase the production capacity. It is applied to blowing the 
plastic films like low-high density polyethylene (L-HDPE) and linear low density 
polyethylene (HDPE) films, etc. It is widely applied to producing the packaging bags for 
food stuff, clothing, rubbish bag and vest ones in both civilian and industrial packaging.
