Our company was contacted by a client from an industrial products distribution company to help them manufacture a large volume of five different types of compression springs for use in the plastic rotational molding industry. After discussions with this distributor, we discovered that their client was employing 75,000 of each item per release, and after only two to three hours of usage, was forced to discard the springs due to failure.
The breakdown of these products was due to the base material having an operating temperature of 250 degrees but was being used at an operating temperature of 500 to 600 degrees. Industrial Spring decided to redevelop a new series of compression springs constructed from precipitation hardening stainless steel type 17-7 PH. The newly designed springs would be able to work in higher temperatures without wearing down so quickly, eliminating the need for replacing the spring anymore than every 3 to 4 months.
Upholding a (±) .005 inch geometry tolerance and a (±) 10% load tolerance, we were able to construct the five types of springs to possess a material size diameter of .042, .045, .056, or .060 inches respectively. And, each product measured 1.485 inches in length and .6 inches in outer diameter.
Within two weeks of design, we were able to distribute an initial production order to our client. We were also able to supply a prototype version within three days of product proposal. By developing these new compression springs that could operate in higher temperatures, Industrial Spring saved the end user money and helped to elevate the distributor’s reputation with his customer.
