Torsion Springs & Torsion Spring Manufacturers
Torsion spring is divided into single torsion spring and double torsion spring. Torsion spring is often sleeve into the pin or shaft, when the external force, that is, according to the spring axis for the axis and produce a torsion force, make the spring roll tight or loose. 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.
