What’s up? Upfeed Displays Are What’s Up: The Next Generation of Retail Displays

Vulcan Spring is proud to showcase their variable force springs designed for vertical upfeed displays. Upfeeds are a fairly new concept in the Point-Of-Purchase display industry. Over the past several years Vulcan has made a significant contribution to the prevalence of these innovative solutions in the POP space.   The standard horizontal pusher displays are a great way to utilize shelf space in grocery or retail stores. But are they the…

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 Deep Look into Space: Constant Force Springs in NASA’s JWST Sunshield

In collaboration with the Aerospace & Defense industries, we are proud to announce our small, yet critical contribution to NASA’s James Webb Space Telescope (JWST) Sunshield project. Set to replace the Hubble Telescope, JWST is said to be six times larger and 100 times more powerful. The Hubble Telescope has provided humankind with remarkable knowledge…

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…

What is Passivation, and Do My Products Need It?

“Specs for my new stainless steel product call for ‘passivation.’ Do I need it?”  Our answer is that you may not. Here’s why. Passivation is a process by which stainless steel can be protected from corrosion by an added layer of oxidation to its outer surface. Although some stainless steel product specifications call for passivation…

Variable Force Springs – Too Cool for School?

Lesson #2 We hope you enjoyed our first blog in this series that provided a general overview of flat steel springs as well as an introduction to constant force (aka Conforce®) springs.  

Design Study: Spool-Mounted Constant Force Springs Used for Dampened Linear Motion

  Design Principles  There are several critical principles that influence the design of a linear motion application when powered by a spool-mounted, dampened constant force spring. These principles support the robust and consistent performance of products in a variety of applications such as automotive and aircraft interiors, industrial machine components, and many other user-interface applications.   The sample assembly shown above will be referenced as an example of various design principles detailed below. This example assembly…

Flat Steel Springs – Too Cool for School?

We hear from a lot of engineers that they learned a good deal about round wire design theory in school but not much about flat springs. Why is that? Who determined that flat springs aren’t interesting or cool enough?   Considering the multitude of industries and products that utilize these types of springs, we think they are not…

How a Consultative Approach to Developing Springs Increases Surgical Stapler Safety

If you work for a medical device company that offers surgical staplers within its portfolio, you understand that the global increase in laparoscopic surgeries is leading to a greater dependence on surgical staples. Close to $2 billion worth of surgical stapling devices were sold in the world in 2016, and revenues are expected to double…
