heavy duty extension springs ,which is of precision extension springs, is applied in many occasions. It has the ability to absorb shock and provides enough tension5.
Internal quality control team makes sure the comprehensive functionality. The product has passed a fatigue tension test
Tension spring is a helical spring subjected to axial tension. There are different kinds of hooks. English hook, German hook, long hook, semicircle hook, duck bead hook and so on. The “hook” is used to guarantee the source of tension of stretching spring. The gap for the ring and the ring must be tight and exact. These points must be identified. It is used to control the movement of machine parts , store energy, measure the size of the force and so on. Some of tension spring are made for precondition for safety. That’s what we value and strict on quality control. We must give more consideration to service this.
