Introduction of Products


NT Die Cutter
The NT Die Cutter (R) is the world's first cemented carbide cutter to be put into practical use. Its process of cutting thin materials such as non-woven fabric and films at high speed contributes to improved productivity.
Our rotary die cutters take advantage of the superior hardness and mechanical strength of cemented carbide to provide a long service life and high-speed production. We offer long-life cemented carbide rotary die cutters that provide the highest productivity in the field of high-speed mass production of thin materials.
