Gas spring for nitrogen gas spring mold (referred to as die gas spring or nitrogen gas spring or nitrogen cylinder or nitrogen cylinder) is a new type of elastic component that uses high-pressure nitrogen as the working medium. It is small in size, large in elasticity, long in stroke, stable in work, and precise in manufacturing. , Long service life (one million times), flat elastic curve, and no need for preloading, etc.It has metal springs, rubber and air cushions and other conventional elastic components that are difficult to complete, simplifying mold design and manufacturing, and convenient mold installation and Adjust to prolong the service life of the mold and ensure the stability of the product quality. It can also be designed as a nitrogen spring system. As part of the mold, it can easily achieve constant pressure and delayed action in the system. It is a flexible performance The most ideal elastic component of the new generation.
