Flat springs may be the optimal solution when exerting force in a confined or restricted area. Take your applications to new performance levels with custom flat springs from Microphoto.
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 photo etched flat spring can be manufactured with specific features and profiles, making them perfect for various applications, including:
Microphoto provides photochemical etching for demanding applications. With a full suite of value-added services, we can take a etched flat spring design from print to production quickly and affordably. Some of our services include:
We specialize in small to larger scale volume manufacturing of photo etched flat & formed 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.
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 and formed 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.
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.
Photochemical etching is best suited for photo etched flat & formed springs versus all other manufacturing methods. The process leverages chemicals to remove material in designed removal areas to produce the finished product precisely.
Etched 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 of the formed spring 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.
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.
