A method for making a metal material composite includes: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling.

A production method for an elongated semi-finished product. A continuously fed wire is rolled by a rotating roller. Along its circumference, the roller has a first segment with a roller profile that rolls a profile into first sections of the wire, and also has a second segment without a roller profile that is rotated contact-free relative to the wire. During the rolling of the profile, the speed of the roller is adjusted in such a way that the speed of the roller profile is the same as the speed of the wire. During the contact-free rotation, the speed of the roller is adjusted in such a way that a length of the wire corresponding to a prescribed length of the second section passes the roller contact-free. A semi-finished product having the first section and having the second section is cut off of the shaped wire.

A system and method for producing a seamless pipe from a hollow billet with a smaller diameter than the seamless pipe, uses a pressure container configured to house the hollow billet. The hollow billet is surrounded by a fluid. A movable punch arranged to fit inside the hollow billet, wherein a hydraulic pressure is transferred from the fluid to the movable punch and to the hollow billet simultaneously, along at least a partial length of the hollow billet. A die opening is arranged serial to the pressure container, wherein the die opening is configured to house a fixed mandrel, the fixed mandrel having a diameter larger than an inner diameter of the hollow billet, so that a gap is formed between the die opening and the fixed mandrel, and the hydraulic pressure of the fluid is generated by an input force from an input punch to move the hollow billet towards the die opening and force the hollow billet material into the gap between the die opening and the fixed mandrel.
