Induction Cap Sealing a Shampoo Container

Induction Cap Sealing a Shampoo Container

THE LAB at Ambrell tested an induction cap sealing application for a company that manufactures shampoo containers. It involved heating aluminum foil inside a plastic shampoo cap for sealing. THE LAB determined that an Ambrell EASYHEATTM 7.5 kW, 150-400 kHz induction heating power supply with a three-turn, two position helical coil would meet the requirements of the client. 

As mentioned, a three-turn two-position helical coil was used to heat the aluminum foil in a tunnel style assembly. The containers passed easily under the induction coil. The assembly was located such that the entire perimeter of the aluminum foil was heated uniformly. The container and cap were placed under the coil and RF power delivered for 0.12 seconds. The aluminum foil heated and sealed to the plastic of the cap. Testing proved the viability of this cap sealing application.

 

Speed (heating time) was important to this client, and this solution met their objectives. This allowed them to boost their production rate. Induction's control and repeatability was also important, as the quality of the seal was optimal and consistent due to the level of control induction delivers. Induction was also easily integrated into their production line due to the small size of the EASYHEAT's workhead. Finally, induction is efficient as power is applied directly to the aluminum and no energy was wasted heating the surrounding parts and materials.
