Latest Patents

One of Schleifstein's latest patents is a method for producing a hollow shaft, specifically a camshaft. This innovative process utilizes an internal high-pressure forming (IHF) technique. The method involves mounting cams and machine elements onto the outer surface of the hollow shaft, ensuring they are positioned appropriately for their intended function. The process includes placing an element with a diameter similar to the internal diameter of the hollow shaft into the shaft. Once the IHF tool is closed, high-pressure medium acts internally while a ram applies mechanical pressure. This dual action allows for the material flow to fill the IHF mold, effectively connecting the cams and elements to the hollow shaft.
