What is induction bonding?
Bonding with induction is a process of mechanically joining two materials using an intermediate material, such as an adhesive. Induction heating can be used to facilitate this bonding process by warming one of the bonded materials to the activation temperature of the heat-sensitive adhesive.
Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces and materials to be bonded.
Benefits of Induction Bonding
Induction delivers precise, repeatable control of the temperature and timing of the bonding process with no open flame or batch process requirement.
Induction's rapid heating reduces process times while easily integrating to in-line and cell assembly operations. Savings from reduced energy consumption, improved joint quality from controlled and non-contact heating.
bonding Application Notes
Select from our collection of bonding notes, taken from years supporting our customers. Read how we helped to solve their process heating challenges.
Induction Bonding Metal to Plastic for Dental Tools
To prepare for induction bonding, the plastic handle was slid onto the picks or mirror and placed inside the induction heating coil and heated
Induction Bonding Steel Cannulas
For each size cannula, the power delivered to the part was optimized to create a bond between the cannula and its bushing, without discoloring the steel of the cannula or causing the bushing to become opaque
Induction Bonding Aluminum & Carbon Fiber Coupons
To enable the process of bonding with induction, three custom-designed single position multiple-turn coils were built to generate the required heating for this application (helical, pancake and u-shaped coils).
Bonding Steel Wire; Rubber Molding
To heat steel wire embedded in rubber molding for a bonding application in the automotive industry
Bonding Steel Tubes to Plastic Tubes with Induction
Bonding with induction took just five seconds with our lowest power unit to deliver the bond just where it was needed.
Debonding Rubber Gaskets, End Rings
It took a modest amount of time to debond the rubber gasket from the metal end ring in this release/debonding induction application. Heat is delivered only where needed.
Induction Bonding Adhesive to a Steel Washer (Automotive)
Bonding with induction heated a steel washer to the target temperature to enabling adhesive curing; it will be part of an automated process for an automotive industry application
Induction Bonding Plastic with a Steel Gasket (Automotive)
Induction bonding enables rapid heating, can easily be integrated into the client's manufacturing process due to modest space requirements and delivers a highly repeatable process.
De-bonding a Magnetic Steel Paint Can Lid
The goal of the induction bonding process is to quickly and cleanly remove the can lid and to pour out paint to reformulate. Induction enabled rapid removal of the paint can lids.
Bonding a Stainless Steel Sheet to a Soundproofing Mat
The part was assembled with the mat in contact with the stainless steel sheet. The part was set on non-conductive material, and placed inside the coil.
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...
Debonding inserts for manifold
A four-turn two-position helical coil is used to debond the inserts from the plastic. The coil is placed against the manifold and power is applied to the two inserts for 15 seconds to soften the plastic...
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
Sealing a Nylon Shell for a fuel vapor Assembly
Filter modules are assembled on the fixture with ring gasket. Pressure is applied to the modules, modules are rotated and induction heating is started. After 10-12 seconds, heating is halted and the modules are removed from the fixture.
Bonding Rubber Gaskets to a Steel Gas Intake Manifold
To bond rubber gaskets to the top and bottom of a steel gas tank assembly.
Debonding rubber coating from a steel casted water valve
Induction heating provides minimal, if any, damage to parts process, is more environmentally-friendly without use of noxious chemicals and delivers even distribution of heating
Debond rubber seal from steel oil seal ring
Induction heating provides highly accurate, fast, more efficient placement of heat, no effect to surrounding components
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
Metal to plastic bonding of beer kegs
A single-turn solenoid coil is placed around the assembled beer keg and heated for 35 seconds as the keg is rotated. Pressure is applied with a press on the top rim whilst the keg is rotating, forming a seal between the aluminium mesh and the two halves of the beer keg.
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
To heat the stainless steel substrate of a solar panel shingle in order to melt the polymer encapsulant, allowing two shingles to bond together with a 3 inch overlap.
Bonding Automotive Trim Vinyl Covering
Heating to 500°F is accomplished through the use of the unique coil; molding is continuously processed at a rate over 20 feet per minute.
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
Heating Aluminum Auto Trim for Adhesive Curing
To heat various sizes of aluminum auto trim to 500°F (260°C) at a rate of 30 ft. (9.1m) per minute for curing an adhesive.
Press-Bonding Metal Clips Into Sealers
To heat metal clips and press-bond them into rubber seals. The metal needs to be heated to 250°F to 350°F with a cycle time not exceeding 3 seconds
What is induction bonding?
Induction bonding is a process in which a precise electromagnetic field is used to heat an electrically conductive material, precisely elevating its temperature, causing an adhesive in an adjoining material to flow and to activate.
Why Use Induction for Bonding?
Induction bonding delivers energy only where it's needed, resulting in faster heating times, reduced potential for process error, enhanced process control and energy savings.
How does bonding differ from curing?
Bonding with induction results in an adhesive joining of two materials where induction curing might involve preparing a thermoplastic medium.
