| A susceptor is a conductive metal material that is used to transfer heat to another piece of metal or non-conductive material. Susceptors are often made from graphite because it is highly resistive and very machinable, or alternatively from stainless steel, aluminum, or other materials. The testing was done in an open air atmosphere. A specially-designed, two turn helical coil was used to provide optimal heating to the cup end of the electrical connector. Initial tests were conducted with bare parts and temperature sensing paints to establish time-to-temperature and heating profiles. Next the solder paste was inserted into the cup area and RF heat was applied with the RF power supply. The optimum soldering temperature of 390°F was reached in 10 seconds, causing the solder in the cup to melt. Parts & Materials Description :
Silver plated copper electrical connector, 0 gage size, solder paste Temperature Required :
390°F Induction Heating Equipment :
3 kW RF power supply, two-turn helical induction coil Operating Frequency :
250 kHz | | | | | | | | |
| Tempering solutions from HF Power Technologies are present in the automotive and automotive-supply industries. In fact, tempering can be performed on all hardened components—bars, joints, shafts, etc. Tempering a component only takes around ten seconds, unlike in a furnace where it can take a couple of hours. The reason is that induction generates heat directly in the material— exactly where you need it. This means tempering can be directly integrated into your production line to improve throughput, increase flexibility and save floor space. | | | | | | | | |
| Our mobile induction heating machine was designed to perform a multitude of induction heating operations for production and research applications. Typical uses include silver brazing of carbide cutting tools, transmission coaxial cables, metal solenoid coil bobbins, etc. There are many applications where the induction method is replacing time-consuming hand-held torches and furnaces for soldering or brazing operations. Thanks to patented technology, improved production and quality can now be realized with the mobile induction heating system. It is difficult to name an industry in which the induction heating process is not employed. A mini-list of popular industrial uses is listed below. The system above is equipped with four, 8 inch diameter, 4 ply pneumatic wheels which allows easy movement from one location to another. A convenient foot operated lock is provided to mechanically stabilize the system during operation. The system above consists of the following components: - Power supply

| Heating Procedure The testing was done in an open air atmosphere. For this application a specially designed two-turn induction coil was attached to a wooden fixture which surrounded the top and sides of the box. The square shape of the coil matched the profile of the box lid and provided even heat around the lid and into the joint area. The box and lid were placed underneath the induction coil and RF power was applied to heat soak the solder in the joint area. As the solder began to flow, a block and tackle rope and pulley mechanism was used to exert a lifting force on the lid. After four minutes, the lid began to release and was easily pulled away from the box. There was no solder splash as the processed concluded. Parts & Materials Description :
14” W x 26 D” x 8” H stainless steel box and lid assembly, soldered together Temperature Required :
400°F Induction Heating Equipment :
5 kW RF power supply, 2-turn, rectangular tube induction coil Operating Frequency :

| To anneal a continuous feed of incoloy stainless steel tubing at 2000°F in a protective atmosphere with a quick cool-down, to eliminate need for additional sandblasting operation. Heating Procedure : A specially-designed 11-turn helical induction coil was utilized to provide even heat to the stainless steel tubing. After initial tests were conducted to establish time-to-temperature and heating profiles, a length of tubing was placed on a PacSci carriage in a protective atmosphere of nitrogen. The carriage conveyed the tubing through the induction coil at a rate of 1.4 inches per second. The 20kW power supply and carriage were activated simultaneously. Optical sensors monitored the temperature of the steel tubing as it passed through the coil, and at 100 inches away from the coil. The power supply was turned off as the trailing end of the tube entered the coil. Parts & Materials Description :
Incoloy 840 stainless steel tubing, .310” diameter Temperature Required :
2000°F Induction Heating Equipment :
20 kW RF power supply, 11-turn helical induction coil with .8” O.D. Operating Frequency :

| Heating Procedure : A specially-designed pancake coil was used to provide optimal heating efficiency and a scanning system was employed to move the coil over the length of the boiler tube. Initial tests were conducted to establish a heating profile and determine time-to-temperature. RF power was applied while the scanning system moved the coil across the boiler tube at a rate of 1 foot per minute. An even heating pattern was observed throughout the heated area.
