As hinge supplier for the biggest wooden eyewear company in US,our hinges are suporier to others in three factores below:

1st: Spring actions: 15000-20,000 times actions after adding oil (openning and closing is counted as one time.)

2nd: Openning angle: control in 22 degree with +/- 2 degree tolerance.

3rd: Horizontal pulling force tester : the spring can resist at least 25 kgs pulling force before it's pulling out of spring box, actually,the real numbers is 25-35kgs as we did double punches on the hinges,on front and back, while others normally 18KGS with one punch.
