Also could change according to clients’ request. We manufacture components in different shapes and sizes to match our customers’ requirements exactly, whether they need blocks or sheets, cylinders, bearings, tips or teeth.Material Matching→Wet Ball Milling→Mixed WC and Cobalt Power→Pressing→HIP Sintering Furnaces→QC Detecting→Packing Tungsten carbide roll ring is a kind of tool which consists of tungsten carbide and cobalt with high hardness and wear resistance. With advantage of high wear resistance, long life and high efficiency of cemented carbide roll ring during the high speed rolling.Tungsten carbide cold rolls is the main products of HengRui, our cold rolls is used in reinforcement wire cold rolling and forming, we had more than 17 years experience to processing cold rolls, and exported to 36 countries since 2006, till now, 0 complain of the quality. Also could make it as per customer requirements. The material of rolls blanks we used are sintered in HIP furnace, 100% virgin material. F: How long is your delivery period?
