GH Group designs, manufactures and repairs inductors
It is within the inductor that the varying magnetic field required for induction heating is developed, through the flow of alternating current.
Inductor design is therefore one of the most important aspects of the overall induction heating machine. A well-designed inductor provides the proper heating pattern for your part and maximizes the efficiency of the induction heating power supply, while still allowing easy insertion and removal of the part.
Temperature uniformity within our part is achieved through correct inductor design.
There is a proportional relationship between the amount of current flow and distance between the inductor and part. Placing the part close to the inductor increases the flow of current and the amount of heat induced in the part. This relationship is referred to as the coupling efficiency of the inductor.
Inductors are often made of copper tubing – a very good conductor of heat and electricity. Inductors are usually cooled by circulating water, and are most often custom-made to fit the shape and size of the part to be heated.
GH Innovation: Advanced Design and Manufacturing
3D Inductors (GH Patent)
The GH Group has patented a revolutionary new system for inductor design and production using exclusive inductor manufacturing method based on the 3D metal printing technology called EBM (Electron Beam Melting). The raw material is pure copper with
Advantages include improved durability and increased repeatability for large scale heating processes such as hardening automotive parts. Production rates can be increased with reduced maintenance and downtime; spare inductor inventory can be reduced. Other benefit is the feasibility to create any inductor shape then the adaptability to complex part is total.
Rotating Inductors are used for hardening bores of large parts that cannot be easily rotated. This patented system avoids the need for parts to be mechanically handled and turned. Parts are fixed while inductor rotates along the Z axis, and the hardening quality and process speed increase dramatically. Other benefits are that the machine design becomes lighter, less floor is consumed and the operation is safer.
