A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

The present invention discloses a stainless-steel tee-pipe moulding process, cutting out a main pipe and a secondary pipe from the stainless-steel pipe to replace the copper tee-pipe to resolve the problem that the copper tee-pipe is easy to corrode and causes water pollution; meanwhile, the moulding process of the stainless-steel tee-pipe of the invention is different from the traditional integral forming process, and saves more materials and reduces the production cost compared with the traditional integral forming process.

In a method for thickening a plastically deformable hollow body wall of a hollow body, with effective radial support of the unthickened hollow body wall on an outer supporting face of an outer mold and with effective radial support of the hollow body wall on an inner supporting face of an inner supporting body, the hollow body is acted on by a compressive force by two application members at application points by moving the application members towards one another in the axial direction with a compressing movement. The application points on the hollow body are distanced from one another in the axial direction. An expansion space of the outer mold is arranged between the application points. Due to the compressing movement of the application members, material of the hollow body wall between the application points is plasticised in the region of the expansion space of the outer mold, and plasticised material of the hollow body wall flows into the expansion space of the outer mold, thus thickening the hollow body wall.

A method for manufacturing a pipe includes: press-forming a plate member into a U shape; and press-forming the plate member formed into the U shape into an O shape. The pipe includes a pipe body and a tapered part tilted radially inward and protruding from one end of the pipe body. Before the plate member is press-formed into the U shape, a boundary between a portion of the plate member corresponding to the pipe body and a portion of the plate member corresponding to the tapered part is pressed from a surface of the plate member corresponding to an inner peripheral surface of the pipe to bend the portion of the plate member corresponding to the tapered part toward the surface of the plate member corresponding to the inner peripheral surface of the pipe.

A method for thickening a plastically deformable hollow body wall of a hollow body includes the steps of arranging the hollow body in an outer mold, arranging an inner supporting body inside the hollow body, applying a compressive force to the hollow body wall by means of two application members moving towards one another in an axial direction with a continuous compressing movement, and performing an axial relative movement of the application members performing the continuous compressing movement on the one hand and of the outer mold on the other hand. Due to the compressing movement of the application members, material of the hollow body wall is plasticized and flows into an expansion space of the outer mold, an axial extent of the expansion space increasing due to the axial relative movement of the application members performing the continuous compressing movement and of the outer mold.
