Manufacturing vs. Traceability in Spring Manufacturing
Compression springs are used in many types of industries including automotive, aerospace, oilfield, and other industries where mechanical devises are manufactured. Many people perceive that automotive and aerospace require high-tech springs that call for grinding a compression spring with extreme precision as an example. It’s not true all the time. Industries requiring high quality standards can sometimes apply to all types of springs, double body torsion springs, flat springs for example, but many times it applies to the paperwork. The paper trail and traceability in the automotive, aerospace, medical and high-tech component industries especially require everything in the trail to match; heat lot numbers, part numbers, purchase order numbers and any outside processing or packaging specifications. Sometimes creating the perfect paper trail for an aircraft round or flat spring for example, can be just as difficult and time consuming as manufacturing the part.
That’s not to say other industries do not have high quality standards. Everyone needs their springs to be manufactured correctly. We in the spring manufacturing industry many times find though that compression springs, double body torsion springs, round or springs, extension springs, torsion springs and wire forms have tolerances or requirements that are specified on the print are unnecessary and drive the cost of the spring higher than it needs to be. We understand industry requirements, especially automotive, aircraft, military and medical require their suppliers to adhere to their particular industry standards, but consult with your spring manufacturer about the specific tolerances and requirements of your spring and its application. One may find savings and fewer headaches in purchasing springs.
