Cold Headed Electrical Contacts

Bimetal Rivet Production Area

Deringer-Ney has been producing electrical contact rivets since 1950. Each year, we produce hundreds of millions of cold headed solid and bimetal contacts. In addition, we use cold forming technology to manufacture other specialty parts..

 

We produce cold headed contacts from a wide variety of materials.
Typical alloys include:

  • Silver
  • Fine grained silver
  • Silver-Nickel
  • Silver-Iron
  • Silver-Graphite
  • Silver-Cadmium Oxide
  • Silver-Tin Oxide
  • Gold
  • Platinum
  • Palladium
  • Paliney® alloys

Our focus is on producing high quality cold headed contacts at a competitive price. Customers find that due to DNI’s attention to quality and consistency, our contact rivets run better than others in their high speed assembly operations.

Focus on consistency and value.

We have numerous years of experience with electromechanical switches and relays. With our on-staff materials scientists, many companies depend on DNI as a technical resource to assist in selecting the best contact geometry and material for each application. We also assist with cost reduction and ROHS compliance.

Our quality systems are supported by ISO 9001:2000 certification, with compliance to the automotive specific clauses of TS 16949 including PPAP, APQP, and FMEA.

In addition to contact rivets, we produce brazed, welded, and staked contacts and contact assemblies.

Cold Forming vs Screw Machining Speeds

Autostaked Contacts

DNI produces millions of autostaked parts using our own contacts.

Autowelded Contacts

High speed automatic welded contacts are an alternative to autostaked rivets. Welding can be more cost effective when the contact material is very expensive or the geometry allows less precious metal than is possible with a cold headed rivet.
