GEng App Note

 

An engineering firm had a new process that required the removal of a coating of insulation. It was important not to heat the material up too much, as the tin-coated copper might then melt. They turned to THE LAB at Ambrell to develop a solution that met these requirements. 

 

THE LAB determined that an EKOHEAT® 50 kW, 15-45 kHz induction heating system would work well for this application. They designed a single position multiple-turn channel coil. A 7.5" x 4.5" (191 mm x 114 mm) area of the tin-coated copper required heating. After applying temperature indicating paint to the part, it took 35 seconds to heat the sample to temperature. The coating was then removed from the tin-coated copper plate. Heating longer length bars would increase the heating time by 10-15 seconds due to conduction losses. 

 

THE LAB confirmed the viability of the application as the part heated quickly for coating release without melting the tin-coated copper. Induction's precise heating, speed, repeatability and the expertise of THE LAB led to the success of this application.
