Induction Heating Steel Assemblies for Sealing

A manufacturer of plastic filtration devices came to THE LAB at Ambrell to see if induction might be a more efficient heating method for their application than their oven. They had been heating steel assemblies in about fifteen minutes and wanted to reduce the heating time. THE LAB determined that an Ambrell EASYHEAT 2.4 kW induction heating system and a pancake coil would be the right solution for their application.

Initial tests were conducted to optimize the power delivered to the steel assembly. Temperature indicating paints were used to determine the heating time. It took seven minutes to heat the sample to temperature, easily exceeding the client’s goal.

Induction offered many benefits to the client and their application. The speed advantage is obvious, and additionally there is no ramp-up time with induction. Induction heating systems take up less room than an oven, making them a good solution for any manufacturing floor that is tight on space. Induction is also more energy efficient as it only heats the portion of the part that requires it. Finally, it is highly repeatable, so the client can expect the same result time after time.
