This extruder, cylinder and screw rods are made of superior alloy steel,
that have been nitrogen treated and processed in a precision way. Hence
it is sound in hardness, durable in corrosion resistance. The
specially-designed screw is of sound quality in plasticizing, which
helps increase the production capacity.
It is applied to blowing the
plastic films like low density polyethylene (LDPE), high density
polyethylene (HDPE) and linear low density polyethylene(LLDPE). It is
widely applied to producing the packing bags for foodstuff, clothing,
rubbish bag and vest ones.
