Induction Heat Treating
Many metals require heating and/or heat treating to achieve their optimum physical properties. Our focus is to lead the market in quality heating and heat treating equipment by providing flexible and innovative systems for long-life performance. Inductoheat heat treating equipment gives you the most flexible heat treating solution for today's needs, and as tomorrow's business changes, our standardized modules can be reconfigured to match your future production needs.
Our induction machines can perform various heat treating applications, such as; scan, single-shot, lift/rotate, pick & place, rotary index and linear transfer.
Induction heat treating is often the most effective process available for a number of applications including surface hardening, through hardening, tempering, stress relieving, annealing and normalising.
Induction heat treating can be performed in a very short time, with extremely high efficiency. The ability to in-line heat treat (compared to batch processing), with high productivity, less distortion and a clean working environment are well known benefits of heat treatment by induction.
Inductoheat manufactures a number of standard products and tailor made machines for the heat treating process. Our range of vertical scanners consists of the Microscan for light duty, small components; Statiscan (download brochure now - 0.3 MB) for medium duty operation and the Uniscan (download brochure now - 0.3 MB) for heavy duty, high volume production. For very large shafts up to 2000mm in length, we have developed the VSM95. All four models in the range feature built in solid state power supply, heat station, programmable control and recirculating quench system.
Our Powermatic is a precision induction hardening work cell for automatic high production applications. It is equipped with its own electromechanical load/unload and reject capabilities. This assures process repeatability by eliminating operator load/unload intervention error.
Our Horizontal Scan Hardening Machine (download brochure now - 0.3 MB) was designed for surface hardening of cylindrical components end to end in a continuous feed for high production applications. This system can be integrated with many of our power supplies and can also be incorporated into cellular arrangements for hardening shock absorber shafts, water pump shafts, heavy duty sewing and knitting needles and many other shaft like components.
Tempering decreases the level of residual stresses set up during the hardening process without losing too much hardness achieved by induction. Tempering also reduces the brittleness of a hardened component.
The conventional method of tempering was to heat the components in a tempering furnace, which very often was in a separate production area, therefore involving extra labour and time for moving the components as well as usually two hours of processing in the furnace. To overcome these disadvantages, in-line tempering with induction was developed.
Induction heating is ideal for annealing cold worked materials. Inductoheat has developed systems to anneal parts with or without a controlled atmosphere. Our in-line systems have been supplied to many different countries for continuous annealing of copper and stainless steel tube after drawing. They are also found in wire production lines.
Specialised Heat Treating Applications
Induction heating lends itself to special processes such as normalising and stress relieving. Stresses caused during a welding or brazing operation can be relieved to restore ductility. Preheating with induction prior to welding can also minimise these stresses.
Inductoheat has even developed special heating systems for the refinement of gemstones.
We also have an impressive record in the field of heating steel strip for the application of organic or metallic coating and heating for metallic transformation.
