A punch press is a machine used in manufacturing to cut or shape materials, typically metal sheets. It operates by using a die and a punch to create holes or specific shapes in the material. The punch presses down onto the material, forcing it into the die, which determines the final shape. This process is efficient for mass production and is commonly used in industries like automotive and electronics. Punch presses can be operated manually or automatically, with various types available, including mechanical and hydraulic presses. They are essential tools in fabrication shops, allowing for precise and repeatable cuts, which are crucial for creating components in products ranging from car parts to appliances.
