DEEN COMPANIES CONTACT ribbons of surfaces Ultrasonic testing Time-consuming, material-destroying quality tests are a thing of the past with us. With the ultrasonic testing we use, we can detect the tiniest cracks in the material and can process them later in the event of surface cracks. This non-destructive testing method protects your products and saves costs. Grinding & Service Center Siegen In our grinding & service center, we grind, mill, burn and test your surfaces on workpieces (blocks, slabs, rods). If necessary, we carry out repair and maintenance work on clamping plates, inlet hoppers, molds (including copper molds), slag pots and other vessels that are common in smelting plants.
