We offer tool steel or bimetallic barrel liners to provide resistance to the abrasive and corrosive properties of today’s resins. The barrel blank liners produced from the outstanding alloys are highly wear resistant and can be used in the toughest processing applications. Bimetallic and tool steel barrels are widely used in injection molding, extrusion and blow molding processes.
Standard bimetallic barrels
A nickel-chrome alloy liner with boron and silicon hardening agents. This barrel offers some abrasive wear resistance and is used primarily for non corrosive resins and can handle 10-20% glass filled resins.
Carbide bimetallic barrels
Tungsten carbide particles dispersed in a corrosion resistant chromium nickel alloy matrix. This barrel offers both abrasive wear and corrosion resistance. Essential for molding resins with 30% or more of glass fillers or mineral fillers.
Tool Steel Barrels
Tool Steel cylinders consist of a sleeve of abrasion resistant material for wear resistance.
