Feed Screw & Barrel Components

Our products meet or exceed OEM equipment performance specifications. We can produce components that match original parts designs and machine new replacement parts that provide greater durability than OEM parts. Call us to discuss our manufacturing capabilities, lead times and pricing for the following components:

Screw Tip Assemblies

We offer a wide range of screw tips and barrel tips including custom screw tip designs. With our tool steel and finish options your new parts can easily exceed OEM parts quality. Additionally, our engineering and CAD design services can provide you with tips having rotating or non-rotating rings that improve shut-off, color mixing and general production concerns. Our non-return valves are designed to facilitate quick shut-off of material flow and ensure a smooth and consistent material flow. Our three piece or four piece non-return valve designs are available for any relative OEM equipment application.

• 3 piece free flow
• 4 piece
• Ball check style
• PVC smear tip
• Thermo-set “Bucher” style
