Hi everyone. Today let’ s talk about spring.
Problems come below if levers and lock rotate many times when use.
According to EN standard and ANSI standard, higher cycle times means higher quality and long-life use.
However the spring is the most important element.
There is a tension testing to find out which Material may be the best choice to be a spring.
According to our experiment, in daily use, 65Mn steel is the economic choice for spring. But for more strict use, high tensile steel should be substitution.

We hope to work with you to make better products for our customers.
