We excel in the design and manufacture of Extrusion Tooling, offering many cost saving opportunities for extrusion manufacturers.

Our tooling can be used to produce wood composite using new or recycled material, either directly through single step counter-rotating conical twin screw extrusion, or in two steps, after compounding using TSE, composites can be produced using conical TSE or single screw extrusion.

Our heads are designed to resolve problems with polymer variations when producing profile and seals of various shapes and sizes.
