The Problem with Ordering 10 Compression Springs from a Long-Run Spring House

Hardware Products Company Is Your One-Stop Shop for Springs

Aside from the fact that a long-run spring house might refuse to take your order because they aren’t set up for the short run, there’s also the possibility that you will end up paying substantially more, and you might not receive your order in time. All because it’s simply not viable for most long-run spring houses to cater to short runs.

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.

Hydrogen Embrittlement and the Process of Electroplating Compression Springs

Very frequently – throughout different walks of life – we hear the term “it is plated.” When referring to jewelry, this usually means that it is not really gold but is made of some cheaper material and gold-plated to look like gold. Springs are very often plated for the same reason.

Compression Spring Parameters and Pi

Compression spring design formulas are really only somewhat complicated algebra. They are quite precise and yield very predictable results. However, when compression springs were first becoming widely used during the industrial revolution, neither computers nor calculators existed.

What’s New in Manufacturing Compression Springs?

Posted by Ted White on Jun 21, 2016 4:15PM

The Evolution of Production Practices 

When compression springs were first invented and manufactured, they were wound on a lathe.  A lathe actually “pulled” the wire around an arbor or mandrel. By today’s standards, that was a crude way to make a compression spring. Mandrels were expensive, so frequently, rather than use the precise mandrel required for the compression spring, the closest mandrel on hand was used. In addition, the space between the coils on the compression spring were developed by the machinist pulling the wire down the mandrel. As a result, the compression spring may well have had varying space between the coils.

9 Key Properties of Alloys in Steel Spring Manufacturing

Posted by Ted White on Apr 20, 2016 2:29PM

Material Selection in Spring Manufacturing Matters

Recently, we wrote about raw material classifications in the steel spring manufacturing industry. These materials are chosen, largely, by their properties and how they will impact the end use. Or think of it inversely: the end use dictates what alloys to choose.

Because steel spring design programs are plentiful and quite easy to use, most engineers know just what they want,

Understanding Material Classifications for Your Next Steel Spring Project

The spring industry, over the years, has divided the common spring materials into different classifications. Some of these classifications have somewhat confusing or misleading names, but are used as jargon within the industry nevertheless.
