Understanding the Double Helical Spring A Marvel of Mechanics

Applications in Various Industries

Small strong springs are fascinating mechanical devices that play a pivotal role in a variety of applications, ranging from everyday household items to complex industrial machinery. Understanding the properties and functionalities of these compact yet powerful springs can provide valuable insights into both engineering principles and practical uses.

During spring manufacturing, the wire is stretched and coiled under force to form the spring shape. This process disrupts the natural balance of the metal's molecules, leaving the spring with residual stress. If not properly managed, this residual stress can lead to defects, cracks, and a reduced lifespan. Stress relief is used to restore the equilibrium of the metal molecules in the spring.
