To produce the different geometrical shapes required around a vehicle´s engine, CNC bending machines can be used for the bending of tubes − crease-free und not affecting the tube´s cross-sections.
END WORKING / PREPARATION
Pipes, tubes and shafts require endwork, i.e. their ends must be prepared for the installation of add-on pieces as, e.g., hoses (which would require hose beads in the tube). For metal connections, elements as, e.g., conical nipples, would be appropriate.
Where conventional techniques do not deliver the desired results, hydroforming can be used to create the desired geometrical forms. This technique uses extremely high water pressure to shape the material.
Welding is used to connect components or fasten individual components for further processing.
Soldering is used to fully connect the surfaces of parts and components to achieve a high strength and/or density.
For fine blanking, the base material is held by a so-called knife-edged ring that follows the cutting profile. A blanking die is then cutting the desired shape into the base material; this technique generates a considerably reduced cutting die clearance compared to other blanking techniques. Further steps within the same working cycle include forming or stamping. Our production includes blanking presses with a pressure force range of 200-600t to process base material with a thickness of 2-14mm.
Our production capacities with injection moulding machines with a clamping force of 20-630t handle volumes of 20-2,000cm3 and final product dimensions of up to 1,000mm.
Our elastomer processing machines (hot vulcanisation) with locking pressures of 80-160t handle volumes of 120-430cm³.
