To heat a copper end cap to temperature for a wax reflow application; the end product is a temperature stat and the client is looking to cut their heating time in half...

Heating a nanoparticle solution to 40 °C

Heat a nanoparticle solution to get it to increase at least 40 °C for medical research/laboratory testing

Heating iron oxide (Fe3O4) nanoparticles in an aqueous solution for research

An eight turn helical coil is used to heat the vials. 0.0625 thick insulation is wrapped around the vial and the vial is placed in the coil. The optical temperature probe is inserted into the vial with the base of the probe located in the middle of the coil turns.

Heating graphite susceptor for glass reflow for X-ray tubes

A two turn helical coil is used for heating. Six graphite susceptors are placed in the nitrogen atmosphere with glass discs and a stainless steel holder.

Heating solutions in vials for cancer research

A four turn helical coil is used to heat the vial for 30 second intervals for five minutes with a temperature reading taken at each interval.

Bonding a Gasket to a Sombrero Nut

A multi-turn pancake coil is used to preheat the nut. It is then transported to the next station where it is pressed onto a gasket for bonding

Bonding Steel Tubes to Plastic Tubes

It took just five seconds with our lowest power unit to deliver the heat to the bond just where it was needed.

De-bonding urethane from a steel insert (doffer pad)

A three-turn pancake style coil is used to de-bond urethane from the steel disc. The part is placed onto two 0.10 (2.5mm) thick ceramic rods on top of the coil and heated for 15 seconds... 

Bonding a stainless steel needle to a plastic shank

A pancake/plate coil is used in this application. Ten assemblies are placed in the coil and power is applied for 1 second to melt the plastic to the stainless steel needle

Bonding plastic sleeve to stainless steel handle for food industry

Induction heating provides highly accurate, fast, more efficient placement of heat, no effect to surrounding components

De-bonding Stainless Steel/Carbon Fiber Assembly

Induction heating process is more environmentally-friendly without the use of noxious chemicals

Bonding Metal to Plastic for Dental Tools

Reliable bonds are produced when the diameters of the preassembled parts are consistent with little clearance before they are heated.

Bonding Metal Housings to Plastic Holders for Lenses

Induction heating improves processing quality by delivering uniform heat to two parts at once using a single-turn €˜peanut' coil. Localized heat enables easy alignment of optical components during final assembly

Fuse thermoplastic catheter tubes

Heating of the mandrel is from the inside out providing a smooth finish on the outside of the assemblies.

Heating Catheter Tipping Die

To heat an aluminum catheter tipping die to above 2850F within 2 to 5 seconds for the forming of catheter material.

Hardening Stainless Steel Surgical Knife Blades

A two turn helical coil with an internal quartz tube designed to scan the length of the blade is used to heat the blade to 1850°F (1010°C) to achieve the desired hardness.

Annealing steel tubes in an inert atmosphere

Induction annealing heats steel tubes to 2000 ºF (1093 ºC) in an inert atmosphere for very small areas within precise production tolerances. A two-turn concentrator coil is used to heat the stainless steel tube. The annealing process takes place in an inert atmosphere to prevent oxidation.

Bonding a plastic handle to a surgical knife

Bonding handle of a stainless steel surgical knife into a plastic handle for very small areas within precise production tolerances

Brazing a heat-sensing probe

A C-shaped steel susceptor is used to ensure even heating and for ease of loading and unloading the samples.

Brazing steel dental tools

To heat a steel tip and shank assembly to 1300°F (704°C) within 3 seconds for brazing with induction heating instead of torch brazing.

Brazing steel orthodontic parts

A four turn helical coil is used to heat parts. Brazing paste is applied to orthodontic parts with a syringe...

Heating a catheter tipping die

A two turn plate concentrator coil is used to heat the die. To measure the temperature on the ID and establish the time-to-temperature relationship...

Heat Setting A Shape Memory Alloy

Heat a steel die to 975°F (523.8ºC) to set (cure) a shape memory alloy nitinol in the correct position.

Molding a teflon catheter tip

Heat a water-cooled steel mandrel to 700°F (371ºC) to form a high quality Teflon catheter tip.

Plastic Reflow With Catheter Tubing

Heat a metal braid in a plastic catheter tube to 250°F (121.1ºC) so that another catheter tube can be bonded to it.

Hardening surgical blades

To quickly heat a steel surgical blade to 2000°F (1093°C) within 2 seconds so as to harden the blade edge.

Bonding Foil to a Plastic Bottle

It was confirmed that the aluminum heated sufficiently to create a bond between the foil and the bottle, meeting the client’s objective.

Heating Steel Shafts for Forming (Medical Tools)

A custom-designed single position multiple-turn helical coil was built to generate the required heating for this application.

Bonding Metal to Plastic for Dental Tools

The plastic handle was slid onto the picks or mirror. The assembly was then placed inside the induction heating coil and heated

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
