Composite Springs and Vibratory

Composite springs are made from cross-ply, isotropic or unidirectional composite sheets. Their composition provides long-lasting and consistent performance in various applications, including vibratory equipment and conveyors.

Composite springs are ideal for applications that require repeatability and high cyclic fatigue resistance, such as sorters, separators, vibratory conveyors, and feeders. Atlas Fibre can machine and fabricate composite vibratory spring materials similar to NorPLY, ScotchPLY, or CyPLY. Learn more about the benefits and uses of vibratory springs.

What Are Vibratory Springs?

Springs play an important role in the operation of vibratory equipment. They store potential energy, which allows them to absorb shock or prevent excessive force from damaging surfaces. A spring can also release stored energy when needed.

The quality of the springs you choose for your equipment affects its durability and functionality. Composite springs are often ideal for vibratory equipment, as they have excellent heat resistance and strength. They also weigh less than other material types, such as metal.

Types of Vibratory Springs

Three types of composite springs are available. Each one has uses in different applications.

  • Coil springs: Coil springs are most likely what you think of when you think of springs. They are helically shaped and either open or close-wound. They can be made from metal or composite materials and are used in many applications, including vibratory equipment and consumer goods.
  • Marsh Mellow springs: Marsh mellow springs are tube-shaped and typically made from fabric and rubber. They can be squished and then return to their initial shape. They are corrosion-resistant but not heat-resistant.
  • Leaf springs: Leaf springs are shaped like a bow and are commonly used in automobiles to support vehicle weight and prevent axles from buckling or snapping under pressure. They are usually made from a composite material, though they were traditionally made from metal. Leaf springs are also often used in farming and construction equipment.

Materials for Vibratory Springs

Composite materials are often ideal for use in the fabrication of vibratory springs due to their heat resistance and durability. Atlas Fibre can help you choose the best materials for composite springs.

Atlas SpringLam

Atlas Fibre sells Atlas SpringLam, a NorPLY alternative offering superior quality at a competitive cost.

NorPLY, formerly known as CYPLY and Scotchply type 1002 reinforced plastic, is a cured glass epoxy composite. It is based on a nonwoven, unique, parallel filament construction, which minimizes the filament stress that reduces fatigue life in reinforced plastics.

Atlas SpringLam is available in cured flat panels up to 48 by 72 inches. Its thickness ranges from 0.03 inches to 2.0 inches. The fiber orientation can be cross-ply, isotropic, or unidirectional. Each option has different properties.

Vibratory spring materials like Atlas SpringLam reduce weight by up to 60% when used instead of steel or another metal. It also provides greater energy storage capacity than spring steel. The material is corrosion- and chemical-resistant and has high dimensional stability in various conditions, including dry, wet, hot, and cold.

Some benefits of Atlas SpringLam include:

  • High strength-to-weight ratio
  • Reduced downtime
  • High impact strength
  • Long fatigue life
  • Low notch sensitivity
  • High strain capability
