Abstract
The purpose of this project is to investigate and solve the problem of sticking between die and sheet metal in a punch press. Initially, the problem was thought to be caused by high pressure, but lowering the pressure did not fix the problem. Further investigation revealed that the sticking was due to the magnetic properties of the die. demagnetizing the die with a demagnetizer has been found to be an effective solution. Another proposed solution is to apply a Tin coating to the die surface to prevent sticking. The aim of this project is to provide an effective solution to reduce sticking in punch presses.
