The Driving Force Behind Automotive Interior Kinematics

It is no secret that the exterior and interior design of vehicles has gone through a multitude of modifications and transformations. As a species, we have seen it all – from the Flintstones Flintmobile/Cavemobile to now electric vehicles and self-driving cars. All jokes aside, what we do know and continue to learn about vehicles and…

A Spring Manufacturer’s Collaboration in a COVID-Specific Medical Application

Battling COVID-19 One Spring at a Time The news came as a shock to businesses of all sizes and specialties. Here in Pennsylvania, on Thursday, March 19th, 2020 – just hours after business closing time – operations were ordered to cease. For sure, a familiar story to many. We were left wondering how a business…

Where There is Smoke… There are Fire Dampers

U.S. Fire Damages In 2019, United States fires accounted for $14.8 billion in direct dollars loss, 16,000 injuries, and 3,704 deaths. The Federal Emergency Management Agency (FEMA) and the U.S. Fire Administration (USFA), “U.S. fire statistics”, reported 1,291,500 fires for that same year. Overall, the USFA estimated 354,000 incidents were residential building fires and 110,000…

Vulcan Spring’s Back to School Quiz

It is late August and the time of the year for pennant races in baseball, pre-season football and of course, the kids go back to school.  To celebrate, we thought we’d make this blog into a fun quiz with some multiple choice and true and false questions.  The quiz includes industrial and point of purchase…

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…

Constant Force Spring Life Cycles

When designing a Constant Force Spring one must begin by taking a hard look at life cycle requirements. This decision will have an effect on every other decision made and ultimately could lead the design down the wrong path. If done correctly, the design can fall into place and allow for a successful project. First,…
