What is a “Die”?

Many people may wonder what exactly a die is.

As the name suggests, a “die” is a “mold” made of “metal.” For example, a cookie cutter used for making cookies is a type of die.

Among the various types of dies, Sekiguchi Seisakusho specializes in those used for punching holes in materials, similar to a hole puncher.

Punching holes may sound simple, but it can involve hard materials, thick materials, and the need to process tens or hundreds of thousands of identical pieces with high precision. For such tasks, a metal mold with high strength and stability is most suitable.
