Vacuum brazing is a preferred thermal method for joining various materials, including challenging materials such as tungsten carbide, ceramics, and diamond-based materials such as solid PCD, MCD, CVD, etc.
Unlike other methods such as soldering with a gas flame, vacuum soldering is environmentally friendly and clean as it does not use flammable gases or fluxes. Power consumption is easily monitored via the machine display.
However, this process is also more challenging, as each material requires individual selection of solder filler wire and different soldering parameters, such as ramp slope, hold time and cooling ramp.
IEW Induktive Erwärmungsanlagen GmbH has developed the VVBM 150, a reliable and Industry 4.0-capable vertical vacuum chamber with a Pfeiffer Vacuum turbo pump and a BECKHOFF PLC controller programmed by IEW for precise temperature control. To minimize contamination and ensure optimum component quality, a metal-free quartz glass tube is used as the vacuum chamber. The 2-zone vacuum chamber enables homogeneous temperatures within the chamber with a deviation of less than 10 °C.
Carefully adjustable temperature ramps reduce the thermal stress of the soldered components and the vacuum soldering process can be reliably reproduced. The VVBM 150 allows multiple product types to be processed in a single soldering cycle, provided they are of similar size, to ensure consistent soldering results. Shop drawings can be assigned to the appropriate programs and stored in the unit to solder matching product groups at the same time.
The VVBM 150 is characterized not only by its advanced technology and precision, but also by its high cost efficiency. The ability to process multiple product types simultaneously in one soldering cycle increases productivity and saves time and energy. The reliable reproducibility of the soldering process minimizes scrap and optimizes material consumption, making the VVBM 150 a cost-effective solution for demanding applications.
The VVBM 150 is the result of IEW's commitment to research and development and enables unprecedented versatility thanks to the innovative vertical arrangement of the quartz glass vacuum chamber. The highly homogeneous temperature distribution within the chamber ensures superior soldering results with a temperature deviation of less than 10 °C. IEW Induktive Erwärmungsanlagen GmbH is proud to introduce the groundbreaking VVBM 150 solution, which takes the precision, efficiency and overall quality of the vacuum brazing process to a new level and sets new standards in the industry.
