Bimetallic barrels are a great choice for industrial applications. They provide optimum protection against corrosion and wear. Reiloy uses integrated process control and inductive centrifugal casting lines to manufacture their barrels. These barrels are available in a wide variety of alloys. They are also suitable for processing corrosive materials.

The process of machining a bimetallic barrel begins with removing a portion of the inner wall of the barrel. The inner wall is the metal surrounding the bore and screw channel. This portion of the barrel is then replaced with a new thin-walled bimetallic or tool steel sleeve. Once this is done, the barrel is placed in a boring machine. A special boring head is used.

In this process, a tungsten carbide alloy is cast into a bimetallic barrel. This alloy has improved wear resistance and uniform carbide dispersion. It is made with a chromium-boron-nickel matrix. The resulting barrel is a high-performance, durable and long-lasting part.

A bimetallic barrel is an alternative to conventional steel, which wears out easily. It can withstand abrasive additives and fillers. Its centrifugal casting method allows it to withstand as much as 50% glass fiber.
