­Pre-Winding Power Springs

When a project calls for the use of a Power Spring, or a Pre-Stressed Power Spring, the design discussion should address initial winding on the arbor.  This initial winding is often referred to as pre-winding the spring. During product assembly the spring is wound on an arbor to a predetermined number of turns.  The main…

Shelf Management: Keeping it Organized with Pullboxes

Recently I went to a “large” retailer to find a few items on my list.  When I was at the checkout counter I witnessed a mild disagreement about a price.  The register rang up one amount, and the shopper thought the price was a much lesser amount.  Of course, a supervisor was called into action…

Counterbalance with Constant Force Springs

Constant Force Springs are commonly used to provide a counterbalance effect for a product.  This blog examines different ways to integrate a counterbalance into a design, emphasizing the use of constant force springs in the manufacturing of a counterbalanced unit.

Design and Function of a Twin Spring or Motor Brush Spring

One of the most unique spring designs produced by Vulcan is called a twin spring.  Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material.  These custom springs are intended to work together, in unison, doubling the force of a single spring.  Twin springs are…

Constant Force Spring Explanation – Part 2

Our last blog discussed the two main types of Constant Force Spring; linear force and torque. As you can see by the following graph, Vulcan is able to change the force of the spring over the travel length to match customer requirements. These springs are referred to as Gradient Positive and Gradient Negative springs.
