2 Company At your service worldwide Emerging from the Bräcker tradition, BalTec Maschninenbau AG in Pfäffikon Switzerland is successfully devoted to the production of Riveting and Press Systems for the fastening technology. In Switzerland, Germany, England, France and USA Baltec has its own sales, engineering and support companies. Moreover there are about 40 representatives world-wide responsible for sales and service. New developments in the field of process monitoring and controlling in the fastening and forming technology made Baltec into a leading company in the technical world and thus pacing successfully into the future times.

3 The latest technology for the most exacting requirements The rose-petal principle The Baltec Radial riveting process is considered to be the most modern riveting principle worldwide. Wherever high-quality joints are demanded, there is no comparable process today. Even joints that were previously possible only with other techniques can now be made by radial riveting. Cost saving through long tool life The closing head is partially formed in accordance with the tool motion. Compared with other methods, this requires considerably less riveting force for a very high deformation rate. The low specific loading conserves the tool and prolongs its life. Excellent surface structure of the closing head With the Radial riveting process, the tool does not itself rotate. The friction between tool and workpiece is thus at a minimum. The result is an excellent surface structure. Low workpiece loading Even bakelite or ceramic parts can be riveted. Lateral forces are negligible. Clamping is usually unnecessary. The tool describes a rose-petal path (hypocycloid) causing gentle, efficient deformation. With relatively little axial force, the yielding point of the rivet material is reached over the small contact area between the punch and the rivet. With the hypocycloid path, the material flows predominantly in the radial direction. This principle gives the Baltec Radial riveting process its name. Perfect closing head formation Perfect closing head formation may be obtained with materials that were previously considered to be non-rivetable. Torsional stress is prevented by the superimposed radial flow direction of the material. The results are outstanding surface quality of the closing head and very high fatigue strength. 3

4 Test laboratory Application tests ensure maximum benefits The optimum solution for jointing methods by means of rivet and press technology (radial rivetings, tangential rivetings, manual, pneumatic, hydropneumatic and electromechanical press systems). The Competence Centre for Fastening Technology in Pfäffikon presents its test laboratory. As you may already be aware we put a lot of effort and dedication into research and testing which has enabled us to develop optimal Baltec solutions. Please test our competence! Micrographs of a closing head Material is deformed by every riveting process; this should take place, however, without influencing the strength characteristics. The new form of motion of the rivet set ensures perfect material deformation without perceptible structural modification of the rivets. Radial Perfect riveting, practically without structural modification. Hammering Very high hardening of the rivets. 4

Without deformation of the lever body. Double riveting simultaneously from both sides. Transmitter plate riveted to the rotor by reshaping the four plastic studs (ABS material). Pneumatic spring tube Zinc die-castings Sealing piston riveted. Possible even with large tube crosssection and wall strenght without flattening. The tube remains perfectly cylindrical. Three rivet joints through sprues on the ribs. Simultaneous riveting of all joints with a multiple riveting head. Steering pinion; automotive industry Steering fork; automotive industry Previously the bearing was fixed using traditional methods with circlips. Radial riveting means that the groove, circlip and the costly assembly are eliminated. High torque is required. Square section shaft was previously welded in. As the male die does not turn with radial riveting, the square section can be riveted without problems. No exposure to heat, no spatter and a 100% safe join. Previously electroplated parts can be riveted without problems. 5
