Vulcan Spring Is More Than Just a Spring Manufacturer

Vulcan Spring is a company that loves what we do and we know that you have put your trust in us since 1967 to fulfill your custom stainless steel spring needs. We are known for making the best constant force springs and having the best customer service of any other spring manufacturer.  Solving problems and…

Vulcan Spring Sponsors the FIRST Robotics Competition in 2013

The kickoff for the FIRST Robotics Competition has begun! January 5, 2013 marked the beginning of design.  Started by Dean Kamen, this robotics competition gets kids to learn the importance of working as a team using science and technology. Teams of 25 students will work together with their mentors to plan, design, think, protoype, program,…

­Pre-Winding Power Springs

Power Springs are used to create a compact power source in applications that require counterbalancing, sometimes through a cable/cord retraction mechanism. The small size and rotational output of Power Springs make them fantastic options for manufacturers and engineers. Vulcan’s Conpower Springs are pre-stressed, producing a flatter torque profile than conventional Power Springs. When a project…

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…

Counterbalancing With Constant Force Springs

Constant Force Springs are commonly used to provide a counterbalancing 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. 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.

Constant Force Spring Explanation – Part 1

What differentiates the constant force spring from the conventional extension and compression (round wire) spring? Hooke’s Law states that the extension of a spring is directly proportional to the load applied to it. Therefore, the further an extension spring is extended, the greater the force.

Creating More Force with a Constant Force Spring

A common practice for mounting Constant Force Springs is to utilize two or more springs to gain more force in a small space. This might be required if the diameter or width of a single spring exceeds the allotted space but there is room to add multiple smaller springs. A much smaller spring design may…

Power Spring and Pre-Stressed Power Springs (Conpower®)

Power Springs are formed by winding strip material on an arbor and into a case or retaining ring. Power springs store and release torque through a central arbor or through the case that it is retained in. Pre-stressed power springs (Conpower®) undergo additional processing to yield a slightly flatter torque curve and increase the available…
