Metallic ingot for impact pressing, cylindrical metal member, and electrophotographic photoreceptor

A metallic ingot for impact pressing includes a contact surface of the metallic ingot to contact a male mold in impact pressing having a maximum height roughness Rz of 20 m to 50 m and an average length of a roughness curve element RSm of 150 m to 400 m, the male mold being to be used in combination with a female mold in the impact pressing.

APPARATUS AND METHOD FOR REDUCING THE CROSS SECTION OF A TUBULAR HOLLOW BODY BY SHAPING THE HOLLOW BODY

An apparatus for reducing the cross-section of a tubular hollow body with a hollow body wall has a shaping die on the outer side of the hollow body, a mandrel in the interior of the hollow body, and a shaping drive with a mandrel drive and a die drive. The shaping die is movable by the die drive to reduce a cross-section of the hollow body with an axial movement of the die. The mandrel is movable via the mandrel drive along the hollow body axis through the die opening in the shaping die. The hollow body wall is subjected to a tensile stress by the mandrel and is drawn in the direction of the axial movement of the mandrel through the die opening. The mandrel drive and the die drive are controlled so that the axial mandrel movement and the axial die movement die are superimposed on one another.
