Induction Shrink Fitting

The purpose of induction annealing is to create a strong mechanical coupling between the two parts. The induction annealing process is mainly used in the assembly and disassembly of mechanical components and transmission units in industrial and mechanical workshops, such as electric motors in the automotive industry.

What is induction shrink fitting?
Induction shrink fitting is a simple and powerful method in the heat treatment process. It uses the principle of electromagnetic induction to preheat metal components to a specific temperature between 150°C and 300°C, causing them to expand them and allow other components to be inserted or removed. In the case of shrink fit, parts made of any metal can be assembled: such as steel to steel, steel to copper, aluminum to steel, magnesium to steel, etc.
How to select induction shrink fitting system?
Induction hardening types are mainly medium frequency, ultra-audio frequency, high frequency and ultra-high frequency, and the appropriate frequency is selected according to the hardening depth. The greater the depth of the hardened layer, the lower the required frequency, and the smaller the depth of the hardened layer, the higher the required frequency. ROCHO’s induction heating power supply adopts the third generation IGBT core components, which is revolutionary in technical structure, and can realize digital control, transmit and store energy monitoring data, and facilitate standardized management.
Benefits of induction shrink fitting system.
Induction shrink fit can accurately locate the heating area and provide sufficient expansion expansion for shrink fit, no need holding and heating the whole large part, allowing workers to easily and conveniently assemble and disassemble the parts. ROCHO INDUCTION shrink fitting machine adopt hybrid LLC series parallel resonant circuit and will be automatically tuned to the induction coil. The system is also equipped with adjustable capacitors and multi-tap output transformers to match a wide range of induction coils and loads.
