Flat Springs

Flat springs may be the optimal solution when exerting force in a confined or restricted area. Take your application to new performance levels with custom flat springs from Microphoto.

Flat Springs Explained

Flat springs are flat strips of material that store and release energy when deflected by an external load. Also called formed springs, they’re typically small and ideal for applications where space is limited.

A flat spring can be manufactured with specific features and profiles, making them perfect for various uses, including:

  • Electrical Contacts
  • Leaf Springs
  • Cantilever Springs
  • Aerospace Applications
  • Disc Washers
  • Appliances
  • Hold-Downs
  • Automotive Applications
  • Clips
  • Shims

Leading Flat & Formed Springs Manufacturer

Microphoto provides photochemical etching and chemical milling solutions for demanding applications. With a full suite of value-added services, we can take a flat spring design from print to production quickly and affordably.

  • Metal Stamping
  • Metal Laser Cutting
  • Wire EDM Machining
  • NADCAP Heat Treating
  • Metal Plating and Finishing
  • Non-Destructive Testing, or NDT
  • Metal Surface Finishing And Edge Rounding
  • Progressive Die Blank Development

We specialize in small to larger scale volume manufacturing of flat springs using your print, specification, or purchase order requirements. Those with a unique need but no approved design are also welcome.

Our experts can work with you to develop a concept and make a prototype. Production of the complete order begins when the design is approved.

Why Choose Us? 

Photochemical etching is best suited for flat springs versus all other manufacturing methods. The process leverages chemicals to remove material in designed removal areas to produce the finished product precisely.

Etched metal flat springs have no burrs. Meaning there are no stress-risers on the part profile, enabling it to withstand millions of cycles without a stress fracture.

Additionally, chemical etching doesn’t alter the remaining material in any way. There are no heat-effected zones or work hardening, and the part profile mirrors the CAD file in smoothness, without striations of any kind.

The Material Experts

When it comes to an assembly, the difference between success and failure often hinges upon material selection. This is especially true when flat springs are involved because failure to release energy can lead to subpar performance or, inoperability.

Microphoto can produce flat springs from various materials, enabling you to receive finished parts with optimal chemical and mechanical characteristics for your specific operating environment.

  • Silver
  • Copper
  • Gold
  • Platinum
  • Palladium
  • Phosphorous Bronze
  • Brass
  • Beryllium Copper
  • Stainless Steel
  • Spring Steel
  • Nickel Alloys

Safe Flat Spring Manufacturing 

Elastic, formable, and highly conductive characteristics make Beryllium Copper ideal for flat springs. . However, beryllium dust is highly toxic, making it harmful to people and the environment. Beryllium dust commonly comes from cutting machines such as lathes, CNC machines, and drill presses.

Microphoto can manufacture high-quality flat springs from Beryllium Copper while complying with Restriction of Hazardous Materials, or RoHS, requirements. We photochemical etch to dissolve designated areas of the material, producing finished products without creating airborne particulate.

Consequently, we’re trusted by clients across many industries to deliver flat springs made of Beryllium Copper and other materials using environmentally friendly processes.

Quality Comes First 

Client satisfaction is our utmost priority. Our material comes from dependable suppliers, and we use precision measuring equipment to ensure parts surpass applicable industry standards and customer specifications.  In addition, Microphoto audits all orders for accuracy before shipment.
