Flat Spring Contacts for Circuit Boards

Atlantic Precision Spring is a USA manufacturer of flat springs and metal clips. We manufacture materials with thicknesses ranging from 0.003″ (0.076 mm) to 0.125″ (3.175 mm), and up to 12.00″ (304.8 mm) wide depending on the intricacy.

As a trusted flat springs manufacturer, we can assure competitive quotes. Our flat spring manufacturing options include fourslide stamping, multi-slide tools, progressive die stamping, short-run tooling or a combination of these methods.

We produce high volume production flat spring runs from an assortment of fourslide machines and power press machines ranging up to 100 tons. These machines manufacture products for many applications including electronic connectors, sensor components, circuit board contacts, small leaf springs, and PC board battery contacts. All flat springs can be prototyped in our secondary department.

Top Flat Spring Benefits When Working with Us Include:

Engineering Assistance

Tight Tolerance Flat Spring

Tight Tolerance Flat Spring

Engineering assistance is available to maximize the effectiveness of your flat springs. We use a spring design program that selects the optimal material, thickness and temper for your application before creating a flat spring prototype.

Rapid Turnaround Time

Customers can expect rapid turnaround time on all productions from the quote process through prototyping and production runs of our flat springs. We draw upon our years of experience in design and development services for a variety of related components, ranging from micro-miniature flat springs to large intricate metal clips.

Best Equipment

Our well-maintained fourslide machines are able to keep precision flat springs to tolerance requirements due to a rigorous maintenance schedule. All fourslide tooling, progressive diesets and short run tooling are designed with 3D software and built using in-house CNC and wire EDM machines by our own tool and die journeymen.

We Produce Flat Springs in the Following Materials:

  • Aluminum
  • Stainless Steel
  • Brass 
  • Beryllium
  • High Carbon Steel
  • Low Carbon Steel
  • Nickel
  • All types of bimetals

Our ISO 9001:2008 certification assures that the procedures are in place to promote complete customer satisfaction in the production of all precision flat springs. Quality assurance is supported by several processes including a networked statistical process control or SPC. Electronic sensors in progressive die sets and fourslide tooling are also used to detect defects in formed parts during production runs. Sensors such as vision systems with inline machine sensors are available to inspect flat springs to identify defects and prevent out-of-tolerance springs.
