Double torsion spring is divided into external double torsion and internal double torsion spring. Torsion spring is a variation of the spring to the extreme, from a single twist to double twist, or even all kinds of torsion rod deformation, according to the design of the formation. Torsion spring is a kind of spring of all kinds of design principle is more complex. And the change of type is quite lively.  The theory that involves in the design is the most vexed also. Therefore, it is difficult to master the design. Our torsion springs produce in all shapes, sizes, small, large, extended length and double torsion springs can all be manufactured to our customer’s special and strict requirements.
