A Twist in the Tale – Springs that Take a Set

Posted by Ted White on Mar 15, 2018 3:36PM

Torsional Modulus and How it Affects the Stability of Springs

In a well-designed spring, torsional movement can occur 10 million times without causing any deformation to the spring. However, if there isn’t enough room to design a spring with enough steel in it, the twisting motion becomes more severe and the wire may not return to its original position. When this happens, we refer to this occurrence as “the spring took a set”.

Spring Rate 101 – A Simple Guide to Understanding Spring Rates

Posted by Ted White on May 30, 2017 1:1PM

Is There Such a Thing as a “Constant” Spring Rate?

If you’re in the business of buying springs, you are bound to deal with ‘spring rates’. The concept can be tricky to understand if you aren’t a physicist or a spring maker yourself. The force that a spring exerts is static as it stretches and compresses, and is a constant rate until its elastic limit is reached. This theory is called Hooke’s Law and we are going to break it down into simpler terms without transporting you back to a physics class.

Why Are Hot Wound Springs Hard to Source

Posted by Ted White on Apr 12, 2017 12:42PM

Pro Tip: Avoid Made-to-Order and Switch to Hot Wound Stock Springs

Known as one of the most labor intensive spring manufacturing processes in the market, hot wound is a process used in manufacturing a spring by heating the steel, winding, and tempering it to the required properties. Hot wound springs can be hard to source depending on your order specifications, urgency, and budget constraints.

The Use of Passivated Custom Springs in the Food Industry

Posted by Ted White on Nov 21, 2016 2:29PM

Passivation and Citric Acid Cleaning

Passivation is one of the more misunderstood functions of spring manufacturing. Passivation is a process: a spring (after it is formed) is cleaned, dropped in nitric acid, and then dropped in water. The process is intended to remove any of the contaminants picked up during the manufacturing process. This is especially required in custom springs that are manufactured to be used in the food industry.
