Demonstration of hot forging process

Video demonstrates a bolt being hot forged. The developed length material is being heated to 1150 C using induction heat. Closely controlled temperature ensures dimensional accuracy and optimal material movement. A wide range of materials are worked and tooling is produced in-house.
