Information on the most widely used ASTM standards within the materials testing industry
Model: NCR-10, ISO 7802
NCR series metallic materials wire wrapping testing machine used for determining the ability of wire of diameter or thickness 0,1 to 10 mm inclusive to undergo plastic deformation during wrapping. The test consists of winding a wire to a specified number of turns around a mandrel of the diameter specified in the relevant standard to form a closely wrapped helix. It may also include a specified sequence of windings and unwinding, or even rewinding.

ISO 7802: Metallic materials -- Wire -- Wrapping test.
The wire winding testing machine tests the performance of wires after being subjected to winding deformation by tightly winding on a mandrel with a diameter that meets the relevant standard requirements for a specified number of helical turns. The testing equipment should be able to allow the wire to be wound around the mandrel, with adjacent coils closely arranged in a helical pattern.
Steel: steel wire, steel rod, steel rebar;
Copper: copper wire, copper rod, copper alloy
Aluminum: Aluminum wire, aluminum rod, aluminum alloy;
Other metal: Rod, glass steel, alloy steel etc.
The equipment structure typically includes a frame, a drive system, a winding device, and a control system.
The frame is designed to be sturdy, ensuring the equipment remains stable during testing.
The drive system provides power and controls the winding speed and direction.
The winding device is equipped with spools of different specifications according to testing requirements to accommodate various wire diameters.
The control system allows for the setting and monitoring of test parameters, ensuring ease of operation and testing accuracy
This wire wrapping testing machine is widely used in various industries. In the metal manufacturing industry, it is used to test the winding performance of materials such as steel wire and copper wire to ensure that products meet industry standards.
The wire and cable industry uses it to inspect the flexibility and durability of conductors, enhancing safety. In the automotive manufacturing industry, wires are used for component connections, and testing helps ensure reliability.
The construction industry may also use this equipment to assess the quality of structural wire.
The wire winding testing machine plays an important role in quality control.
