What Is a Die Punch? A Guide for Stamping and Mold Professionals

Stamping and mold workers use a type of specialized equipment known as a die punch to take shapes and designs out of various materials, such as metal, plastic and leather. It’s a metal tool that resembles a cookie cutter with sharp edges. It cuts out the shape or design you desire when you press it down on a material.

The Importance of Die Punches

For workers who are in stamping and molding shapes that need to be precise and the same every time, the die punches are the ones that count. Many items, including metal jewelry, leather goods and plastic parts, would be difficult if not impossible to produce without the use of die punch. Placing the product with a die punch ensures that all the pieces look the same, you get a more consistent and quality product.

Choosing the Right Die Punch

In choosing a die punch for a project, consider the material you will be punching and the intended shape. Die punches run the gamut in variety, which is why choosing the right one matters. For instance, round die punch set is excellent for circles, heart-shaped one is perfect for hearts.

Tips for Using Die Punches

Use a die punch properly by laying the material over a firm, flat surface and pushing down. However, even pressure will also help you get a clean cut. It also helps to put a bit of oil on the edges of the die punch to prevent sticking and just to make cutting easier. Don't forget to clean the die punch frequently so that he will be sharp and work well.

Common Mistakes to Avoid

One mistake that is easy to fall into is pressing too hard, which can tear away the material or cause rough edges. You want it to be gentle, but don’t push so hard you end up with a raggedy cut. A second mistake is exercising a die punch that is not sharpened, leading to jagged edges and inconsistent shapes. Be sure to keep the die punch sharp, or replace it when necessary for optimal outcomes.
