RP 9 - Rotary Index Table In the RELCO family of HF welders, the RP9 is the mid-range rotary index machine. The design incorporates all necessary features to achieve FAST, ACCURATE and RELIABLE welding over a broad product programme. Additional operations such as Print Stations and Pick and Place Robots can readily be incorporated where manufacturing schedules apply. The unique mechanical design of the "C" frame press produces very high pressures for minimal air consumption. This is achieved with a very fast movement during the free fall giving way to a controlled build-up to maximum pressure during the weld cycle, thus giving ideal welding conditions. The HF generator is of latest design based upon easily exchangeable printed circuit boards and a 24V control system. The RP9 is available with alternative generators e.g. 6 & 12 Kw as well as different platen sizes and rotary table configurations.
