From a paper-intensive process to digital mold manufacturing.
The mold spectrum of BOSCH Formenbau GmbH in Mühlhausen includes the production of precision injection and die casting molds weighing 0.5 to 15 tons. Molds for injection-molded parts are produced by 1K and 2K methods for the safety, electrical equipment and automotive industries. As a supplier of die casting molds for aluminum and zinc, Bosch Formenbau is a highly valued partner of OEMs and their suppliers. Digital mold manufacturing was implemented using Tebis – on the one hand, to meet customer requirements for shorter and shorter processing times, and on the other to offer customers the widest possible window of change for data optimization. With the new Tebis Measure module for measuring electrodes, the last interface is now complete.
Bosch Formenbau GmbH in Mühlhausen has relied on CAD/CAM products from Tebis for over 12 years. When they first began, the mold was still designed on the drafting table or in a 2D CAD system. The CAD department then used Tebis to redesign the mold as a 3D data set just to calculate the milling programs. At that time, 3D design was only a means to the end of generating the milling programs. As CAD/CAM systems very quickly became more powerful, Bosch switched over to 3D design at an early stage. The entire manufacturing process has been structured based on a complete 3D design of the mold for over five years. And the mainstay of the operation is the Tebis Viewer technology. It gives all personnel full-time access to the current data, and it is used all the way from acquisition through NC machining to assembly. The 3D data set for die design always remains the central medium of information.
We are currently achieving a savings of at least 25% per electrode in electrode design, which is certainly a significant potential with our production of more than 5,500 electrodes per year.
