Precision Metal Stamping

Metal stamping is a fabrication process by which flat sheets of metal are formed or cut into a desired shape using pre-cut dies. Stamping incorporates a variety of techniques, such as punching, blanking, bending, coining, flanging, and more. To ensure accurate stamping, the die is designed using precision computer aided design (CAD) software. Since stampings require a certain amount of clearance, precision dimensions for the dies are particularly important.

For more than 57 years, Norstan has been a leading producer of top quality precision stampings for electromechanical assemblies and contacts. Our ISO 9001-certified facility includes an extensive portfolio of state-of-the-art manufacturing equipment, enabling us to offer custom fabrication of stamped contact parts and electromechanical stampings. Our highly experienced staff have the necessary expertise to overcome even the most stringent challenges.

Where are Stamped Parts Used in Electromechanical Devices?

Norstan is pleased to provide components for a broad range of electromechanical devices in automotive equipment, household appliances, aerospace equipment, and elevator controls, among many others.

Switches and Relays

A switch is defined as a component of an electrical system that establishes, removes, or redirects electrical current by establishing one or more connections in the conductive path within a circuit. Switches may often have numerous contacts that operate in unison, sequentially, or in an alternating fashion. Light switches are perhaps the most common example of a switch, which closes to allow electrical current to flow to the light when on and opens to interrupt the electrical flow and turn the light off. Switches may be operated manually, using a button or lever, or they can operate using pressure, temperature, or sensors to trigger the motion of the switch.

Switches and relays differ slightly. A relay is a specific type of switch that is operated electronically, often using an electromagnet. Relays automate the opening and closing of circuits in complex electrical systems that cannot operate efficiently under manual control. They require very little electricity to operate, and can be used to direct the flow of much stronger power signals.


Electromechanical timers consist of electrical and mechanical components used to start and stop devices at pre-programmed times or intervals. They may be operated through the use of rotating wheels, thermal expansion of metallic components, or an electronically operated motor connected to a cam or gear system.

Thermostats and Controls

Electromechanical thermostats and controls often use rotary timers to program day and night temperature settings. Using a combination of temperature sensors, thermal expansion of metal components, and timers, they are used to control heating and cooling elements to ensure proper environmental temperature.

Typical Manufacturing Processes

Norstan’s automated precision stamping processes reduce labor costs, especially as production volumes increase. This makes metal stamping a premier choice for small and large volumes of metal parts requiring accurate and cost-effective production methods.

Additionally, many technological advances have been made over the years to enhance the precision of metal stamping operations. For example, 3D design capabilities have sped up the design process, while wire burning of die components has helped to produce quicker manufacturing capabilities and more precise components.

Some of the manufacturing processes we employ include:

  • Forming – A die and punch bend the material to a predetermined angle.
  • Coining – Displaces workpiece material through the application of extremely high levels of force.
  • Embossing – Creates raised or depressed features on sheet metal.
  • Tapping – Creates threaded holes in a workpiece.
  • Welding – A method that uses heat to conjoin materials.
