Baltec application for electrical solenoid sensor

Electrical solenoid assembly

Roll forming application with limited access through interferences are a welcome alternative to crimping. In this example it is about roller forming a canister with interruption.

Closures of solenoids and sensors typically need to be watertight. Additionally access to the area that needs to be closed is limited or difficult. Roller forming is a well suited process, but overcoming the interference is a challenge. 

Combining a customized roll forming head with the servo controlled ELECTRIC roll forming machine is a perfect solution.
This setup allows for the roll forming head to be oriented in a defined position while advancing to a position where the interference is no longer an obstical. Rotation and forming at this point can commense. After forming, roll forming head stops again in a defined position, from where it can return to its home position.
