Our Unique Finish - ExtremEtch™
ExtremEtch produces an evenly distributed matte coating, without sacrificing the high tolerance features needed to meet our customers' extrusion requirements. Some of the great benefits of this process include the ability to hold the tightest tolerances and create the distinct matte finish.
