Ambrell's induction heating systems provide medical device manufacturers with reliable, repeatable, non-contact heat, with control and accuracy focusing energy to a specific part area. 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 to be heated. Can we help? ## Benefits of Using Induction in Medical Device Manufacture Induction meets tight production tolerances delivering precise localized heat to small areas creating pinpoint accuracy. The process increases production rates with faster heating cycles, reduces defect rates with repeatable, reliable heat and eliminates variability from operator-to-operator, shift-to-shift. ## Medical Device Manufacturing Application Notes Open panels to select from our libraries of notes Annealing Annealing steel tubes in an inert atmosphere Induction annealing heats steel tubes to 2000 °F (1093 °C) 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. Annealing steel wire for a medical application Induction annealing achieved the targeted steel wire temperature within three seconds. Ambrell performed a free laboratory test, designed a cost efficient, in-house process and connected them with an automation partner to maximize productivity. The client now has better control over their end product. Annealing Stainless Steel Braids Heating took just 2-5 seconds depending on the sample used, meeting the client's requirements. Annealing a Stainless Steel Medical Wire  Some process development may still be needed at the customer site once the induction system is delivered to account for the unique fixture/ handling techniques used  Bonding 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 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.
