Multiple-Temper Springs

Source: Meier Tool
The company is a leader in metal stamping. They are capable of producing flat, formed, or drawn parts and equipped to produce automated assemblies with other components right in the press.
The company has developed a process to form an electrical contact that results in a part with multiple tempers.

The resulting part has excellent springback memory and high contact forces while still allowing for effective crimping and bending in the wire connector area. The finished part can also be soldered if the application requires it. Yield strengths of 180 ksi for the spring and 30 ksi for the crimp can be achieved in miniature and micro-miniature parts. The crimping of hardened, high-performance springs has simplified customer assembly operations, saving assembly time and costs.

The company is a leader in metal stamping. They are capable of producing flat, formed, or drawn parts and equipped to produce automated assemblies with other components right in the press. Whether customers provide a rough idea, detailed print, or a complete CAD file, the company starts every project by first learning the function of the component. Expert Design Engineers, Tooling, Production, and Quality personnel will take an in-depth look at each aspect of the component and suggest ways to improve performance or reduce costs.

The company has completed the development of a rapid prototype system that allows for quick turn-around of precision metal stampings with a process that closely simulates the results of a high speed progressive die. Engineering and development costs are kept to a minimum through the use of interchangeable tooling components. Only the tooling that is specific to the product design is custom made. This tooling is inserted into a prototype system that cuts and forms with the same process used in the production operation. Using this method, prototypes most closely resemble the end product by displaying typical cut-by, shear, and other features that only result from stamping the parts during high volume production.

Prototype development results are fed into the progressive die design to ensure product quality on the first volume production run. Components as thin as .002 in. are produced this way. Any number of alloys are used, including stainless steels, titanium, nickel, beryllium copper, and precious metals. Prototypes can be designed and manufactured in 1-4 weeks, depending on complexity. This process is used for projects with expected annual volumes of 50,000 pieces or greater.
