Industries we serve

Capital Spring caters to a wide variety of industries, offering the highest quality products and value-added services such as design consulting that help improve manufacturability and speed to market.

Our Manufacturing Services

  • MW Components 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.

  • Milling

    Milling is accomplished using computerized controls to operate motorized cutting tools.

  • MW facilities use several methods to stamp or form sheet or strip metal into a desired shape. Some examples include stamping and fourslide. Stamping uses a die and applied force to create a product, where fourslide uses multi-slide technology to bend and manipulate metal into a desired form.

  • 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.

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

  • Plating

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

  • Shot Peening

    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.

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