This process is suitable for heating bearing housings, slots, guide rings, wheels and other machine parts, for assembly by shrinking. During heating the dimensions of the outer part increase due to thermal expansion. When the desired size increase is achieved, assembly can be done, and after the outer part cools and shrinks, a tight fit is created according to the planned overlap.

Characteristics of the technology:

• This technology gives a well-defined, reproducible result. It can be easily integrated into an automated production process, and is energy-saving and environmentally friendly compared to traditional methods.
• The frequency of the generators we manufacture is set to a range that ensures homogenous, adequately deep heating of the part so the thermal expansion is uniform and it ensures a constant assembly gap.
• The control unit of our equipment ensures the intelligent adaptation of the preset heating recipes for each heating, thus compensating for the production variance of the parts and other changing conditions. It is possible to control the equipment based on time / current / power / energy amount / temperature/ component size.
• The excellent efficiency of our generators ensures low specific electricity consumption. The power and consumption meter functions provide continuous feedback to the operator.
• Our equipment is able to transmit the measured and set parameters of each heating process for logging purposes with an autonomous measuring system, thus enabling the tracking of the heated workpieces by serial number.
