Why Choose a Bimetallic Screw Barrel?
If you’re searching for “bimetallic screw barrel”, you’re likely dealing with serious production issues—frequent screw barrel replacements, poor wear resistance, and rising maintenance costs.

In high-output extrusion and injection molding environments, standard nitrided barrels often fail to withstand abrasive materials, corrosive additives, and high processing temperatures. That’s where bimetallic screw barrels come in.

What Is a Bimetallic Screw Barrel?
A bimetallic screw barrel combines a tough alloy inner layer with a durable steel body. This inner lining—usually made from nickel-based or iron-based alloys—offers:

Excellent wear resistance

Superior corrosion protection

Extended barrel life (2–3× longer than nitrided types)

It’s especially recommended for processing recycled plastics, glass-fiber reinforced materials, PVC, flame-retardant compounds, and filled resins.

What Problems Does It Solve?
✅ Short service life – Bimetallic barrels significantly reduce replacement frequency.
✅ Product inconsistency – A stable inner surface ensures uniform melt flow.
✅ Maintenance downtime – Less wear = less frequent maintenance.
✅ High long-term costs – Although more expensive upfront, it lowers total cost of ownership.

If you’re tired of dealing with damaged barrels and production stops, upgrading to a bimetallic screw barrel could be the best investment for your line.
