Polishing of plastic extrusion tools

Surface quality of windows, doors, and other plastic profiles (PVC) is highly dependent on the finish quality of extrusion dies, apertures, and calibrations.

This is the difference between conventional extrusion dies, and dies polished with MicroStream Abrasive Flow Machining.

With MicroStream technology, dies are polished in the extrusion direction.

This process results in optimal surface roughness values that give the extruded profile a perfect surface. Many leading manufacturers of plastic profiles have been applying our method for years to great satisfaction.
