Thermocompression units

Thermocompression welding is a process of welding parts from dissimilar materials, carried out with heating under pressure. The essence of the process is as follows: when pressure and temperature are applied to the surface being processed, the material of one part settles and begins to flow along the second part. As a result, the contact point is heated, cleaned of the oxide film and other foreign formations, the surfaces are brought together as closely as possible, and a dense weld is obtained. The advantages of the described process include low sensitivity to changes in operating parameters, stability of the entire welding process, and process controllability by monitoring pressure and temperature. Thermocompression technology is used in powder metallurgy to create products from refractory materials, dissimilar metals, and composites. By varying the process parameters, it is possible to obtain complex-shaped parts with identical compositions but different physical and chemical properties. Hot core punching and mandrel punching processes are used in critical areas of complex product production when other production technologies do not allow obtaining a product of adequate quality. Thermocompression units manufactured by NPO GKMP are manufactured according to the customer's process chart or strictly in accordance with the technical specifications. Due to the availability of our own production of electrothermal equipment, as well as extensive experience in creating sealed chambers, sealed inputs, controlled hydraulic cylinders, pneumatic cylinders and compression oil stations, it is possible to manufacture thermocompression units with various values of working pressure - from several kilograms to tens of tons, and temperatures - up to 2200 ° C. Thermocompression units manufactured by NPO GKMP are fully automated. The control system clearly processes feedback on the temperature of the welded joint and the applied force. The composition of the atmosphere or the degree of vacuum inside the chamber are continuously maintained at a given level. The control system fully processes all known emergency and abnormal situations, and in the event of a non-critical failure will help to successfully and safely complete the process.
