To help you get a better understanding of the process of spring making as it relates to your spring needs, we’ve put together a comprehensive glossary of spring terminology, keeping you–the buyer–in mind:

Deburring – Several processes are available of which all have the end result of removing any loose or protruding bits of steel from a finished part.

Design Assistance – Implementing the Spring Manufacturers Institute software to verify customer spring designs. 

Grinding – Removal of round-shaped material at the ends of the spring for the purpose of making the spring stand flat and square on a flat surface. The ends are made flat by grinding to provide a flat surface.

Lathe Coiling – Pulling wire around an arbor to produce springs, cold working process.

Painting – Color-coding to customer specifications.

Passivating – Acid treatment of stainless steel to remove contaminates and improve corrosion resistance partially lost during the manufacturing process.

Testing – Use of automatic electronic testing equipment to ensure quality standards are met. 

Tooling – In-house tool and die making to provide installation assistance during production.

Wheelabrating – Shot blasting with steel grit or shot thrown from a spinning wheel patented by Wheelabrator Fyre.

Plating – Ensures corrosion resistance or used for electrical conductive purposes. For e.g. Zinc, tin, electro-less nickel, and hot tin solder.

Ring Making – Utilizing many exotic alloys and shapes to produce precision connector rings.

Secondary looping and bending – Cold work process done in the secondary department or on CNC machinery.

Setting – Cold work process done to prevent the loss of length and load at operating heights by presetting the spring to remove all of the length loss before you ever see it.

Shotpeening – Cold work process in which the material is peened to induce compressive stresses and thereby improve fatigue life.

Special Packaging – Fulfilled as per customer’s requirements.

Stamping – Cold work process to produce flat springs and clips implementing specially produced dies to hydraulic presses.

Winding – High-speed process of twisting spring-tempered wire into a helix by machines specifically designed for such an operation.

Wire Forming – Use of the latest CNC equipment to ensure accuracy of wire formed parts.
