Gears in universal machines in the building and automotive industry - fatigue strength is increased, deformations are reduced and necessity of finish grinding falls out. Shafts, axes, precise screws, mandrels, pinions and guide bars - wear resistance and fatigue strength are improved and the volume of finish operations is reduced. Wheels, cylinders and other parts of plastics processing machines in warm extrusion - durability of nitrided parts is prolonged and the quality of plastic goods improved. Swages and press moulds for metal and metal alloys casting - wear and corrosion resistance is increased and metal sticking is reduced. More materials can be selected for plasma nitriding, including cast iron, mild steel, mold, tool, high speed and stainless steels. Cutting tools with extensive chip throw-out such as mills, discs, bits, drills, taps, broaches etc. - cutting ability is improved, wear resistance and production capacity is increased.
