Aluminum extrusion

Walter Krupp supplies honing tools and industrial abrasive brushes for aluminum extruders and processors, which in turn supply the automotive, electronics and household appliance industries. From condenser tubes, air conditioning units and car radiators to heat sinks used in electronic products, manufacturers require aluminum extrusions that are burr-free and slightly rounded. This is why suppliers turn to Walter Krupp for the Flex-Hone® tool and industrial brushes such as NamPower™.

With its soft cutting action and low-temperature abrasion process, Flex-Hone® exposes the base metal structure of aluminum to create a smooth, durable surface. Removing loose, torn and folded metal eliminates burrs and prevents flaking, which can hinder heat dissipation. For surface conditioning, the nylon abrasive brushes are ideal for improving the finish after extrusion. NamPower brush tools are used for surface finishing and blending tool marks after machining or grinding.
