Rolling threads is the most versatile and accurate rolling method, characterized by the widest technological capabilities in the manufacture of threads of various diameters, lengths and precision.

The wear resistance of thread rolling dies from Taiwan is 4-5 times higher than regular thread rolling dies. This is achieved by the brand of material used and an innovative approach in the field of production.

Thread rolling is a process that has been around for more than one hundred years and there are machines in service that make the fifty-year old ones look young by comparison. Thread rollers come in a variety of types and sizes, but they all use a mechanism where hardened steel dies are matched and set to penetrate with force in order to reshape the material surface of a round diameter into a thread form.
