Century Spring offers prototypes or sample parts for a variety of custom components including springs, fasteners, bellows, couplings, and other precision metal parts. We also offer rapid prototyping for select components, with shipping in as little as one week.

CNC machining is a manufacturing process where computer software is used to control complex tools or machinery without the need for manual operations. Some examples of CNC machining services we offer include milling, turning, micromachining, metal stamping and forming (including fourslide technology), and wire forming and wire rolling.

Wire forming and rolling processes are used to bend or form cylindrical metal stock into a desired shape and length, many times using high-tech machining software.

We perform precision sharpening and CNC grinding services including electrochemical grinding in the production or finishing phase as needed for your intended application.

Outside of hardening and tempering, we offer a variety of other heat treatment options to ensure your desired ranges are reached for cycle-life, toughness, and resistance to environmental forces.

Plating is a manufacturing process where a thin coating is applied to a component’s surface through chemicals or electric current (electroplating).

Shot peening refers to a process used to create a stress layer on metal parts to increase durability. In this process, small round materials or shot are used to repeatedly strike the surface of the part to increase hardness and strength. Shot can be composed of anything from ceramic or glass to metal.

Do you need specialized packaging? We work with your teams to determine the best way to build and package your products to ensure efficient assembly with your existing components.

Cycle testing, or life cycle testing is a process where products are tested to ensure adequate life cycle or product lifetime under regular working conditions.

This is an NDT process where a magnetic field is added directly or indirectly to the component and used to test certain metals like nickel, cobalt, iron, and their alloys for shallow surface inconsistencies.

Optimize your designs to reduce cost, improve performance, and accelerate time to market.

Coating is used most often to resist environmental factors like corrosion or embrittlement.

NDT or Non-Destructive testing is a broader term used to describe multiple testing techniques used, particularly in technology and science, to test components or materials without damaging the testing materials.

Rockwell testing is a specific method used for testing the hardness of materials like metals and some plastics. The Rockwell scale measures penetration of the material when force is applied.
