Forming metal by bending and trimming it to various sizes Norstan specializes in meeting customers’ critical tolerances from micro sizes to large stampings. Our in house expert die makers allow us to be both competitive and maintain high quality tooling for our customer’s needs. We provide improved quality control utilizing electric detectors in-die and quality inspectors checking dimensions and tolerances with computer aided photo measuring devices and equipment.
Tooling is built to combine several operations thereby saving money and providing manufacturing processes with greater quality control. Norstan forms the stampings and also can in-die stake, weld and even in-die tap and perform other operations as required to meet our ...
Brazed composite heading marries two metals together by bonding them under controlled conditions in a furnace. The bonding material is called a brazing metal alloy, which is a low melting point metal/alloy used to attach and metallurgically fuse two metals together after elevating the temperature beyond its melting point.
A machine composite part is made out of silver (or certain silver alloys) cold bonded in a heading machine to a copper shank rivet backing. Special heading equipment and expertise is used to mechanically bond these two different metals together, both saving money and reducing lead-times. Norstan, Inc. refers to these as machine composites.
A solid state rivet contact is a part with a head larger than its body or shank. It is designed to be clinched (or staked) onto another part of an assembly. Solid heading utilizes one metal throughout the entire part – all copper, brass, all silver, or alloys. Our cold heading equipment forms your parts from wire.
Globally, there are only a few companies that cut and braze contacts made of tungsten. Of these, only Norstan is based in the United States. Some applications of tungsten contacts include solenoids and horns.
Solid and composite weld buttons and discs are contacts with no shank. Buttons are brazed or welded to another part, whereas disks are welded or brazed to a backing. Norstan makes buttons and disks out of a variety of materials. Our various configurations can be utilized in a broad range of applications.
