Flat Spring Contacts for Circuit Boards

Flat Spring Contacts for Circuit Boards

Atlantic Precision Spring produces the best precision flat springs, flat leaf springs, custom 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 due to our arsenal of manufacturing processes. These 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 springs 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 parts can be prototyped in our secondary department.

Some of Our Top Benefits Include:

  • Engineering assistance is available to maximize the effectiveness of your metal and spring clips. We use a spring design program that can select the optimal material, thickness and temper for your application before creating a prototype.
  • Customers can expect rapid turnaround time on all productions from the quote process through prototyping and the volume production runs. 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.
  • Our well maintained fourslide machines are able to keep precision metal clips 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.

Tight Tolerance Flat Spring

Tight Tolerance Flat Spring

Our ISO 9001:2008 certification assures that the procedures are in place to promote complete customer satisfaction in the production of all our flat and metal clips. Quality assurance is supported by several processes including a networked statistical process control “SPC.” Electronic sensors in progressive diesets 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 formed metal clips to identify defects and prevent out-of-tolerance metal clips.
