   Variable force springs and variable torsion springs can expand negative gradients and positive gradients to form a single spring. It breaks through the influence of the traditional spring affected by Hooke’s law, so that the stroke and force are no longer proportionally increased, but accompanied by various elastic force-displacement combinations, such as negative slope. Therefore, a stepped constant force can be achieved.

Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications. What products can the curve changes of variable force springs be used for?

     Pen Type Drug Syringe Application
The spring exerts a constant force to keep the drug flow in place, preventing patient discomfort during use. It has a stretch at the end of the stroke to ensure that all of the medication can be fully injected.
     up and down sliding door
    When the door is closed, the spring force is less than the door weight; when the door is in the middle stroke, the spring force is equal to the door weight. When fully open, the force applied by the spring is greater than the weight of the door to ensure the door does not slip.
     Shelf pusher
     The spring outputs a variable force to match the number of displayed items. A large thrust can ensure that a large number of displayed items can be pushed smoothly, and a small thrust can effectively push small-quality items to avoid flattening of the exhibits.
     Cordless curtains

    Variable torque springs can be applied to cordless shades, allowing users to easily adjust shades up and down. The springs apply progressively less torque, creating a gravitational balance that allows the curtain to stop at any height.

 "My new stainless steel product specification requires' passivation '. Do I need it?" Our answer is that you may not. That's why. Passivation is the process of protecting stainless steel from corrosion by adding an oxide layer on its outer surface. Although some stainless steel product specifications require passivation to reduce corrosion risk, most of them are unnecessary and expensive,...

   Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while...

 In most types of springs, when the spring is compressed and then relaxed, the force applied is proportional to the distance the spring is stretched. Unlike ordinary springs, constant force springs do not comply with this rule. Due to the physical design of constant force spring, its return force remains constant. Therefore, constant force springs are useful in many applications that require consistent recoil....
