Feature(may vary by option.)

●2,Material: It is made of spring steel,which is not afraid of bending and has good toughness.
●1,Excellent elasticity: high plasticity,good fatigue resistance,uniform force,good firmness,and good texture.
●4,Fine workmanship: It is made with a high-precision spring machine. After multiple processes,each production process is strictly controlled,with small tolerances,and a smooth surface without burrs.
●3.The working principle of: Torsional springs are mechanical parts that use elasticity to work. Generally made of spring steel. Used to control the movement of machine parts,ease the impact or vibration,storage energy,the size of the measurement force,etc
●Durable, high temperature resistant and anti-corrosion, superior longevity.
