The material of shaped wire spring can be produced in square, rectangular, half-round and other custom shapes. In order to achieve high load and durability, it is necessary to use the profiled shape for design.
The constant force extension spring is mainly used for the recovery of the tension force. Different from the extension spring, constant force extension spring does not occupy space. When it is deformed and displaced after being stressed, the spring constant remain the same. And its material must have high tensile strength properties.
