Drawing

The first step of the magnet wire manufacturing process is drawing. Using our UDM drawing machine, we process ½” and 5/16” copper rod down to the custom round size needed for the next step of the manufacturing process

Rolling

The second step of the wire process is to roll through either our 3-stand or 2 stand rolling mills in order to flatten the round process wire into the final wire size ordered by the customer.

If the end product calls for the wire to be covered only with either polyimide film, Mica, Nomex® or Daglas, the bare wire is annealed in our Lindberg batch ovens.

Covering

We have the capability to insulate wire with mica, Kapton® film, Apical® film, Nomex® paper or Daglas. If required we can supply Daglas in a varnished form.

Enameling

We enamel wire to NEMA standards or specific customer specifications. We can manufacture NEMA 36-C 200 degree enameled product (CW200) or NEMA 20-C 240 degree product (CW240ML).

Conform ™ Extrusion Technology

The use of a single revolving wheel as the driving force in the Conform continuous rotary extrusion (CRE) process enables the manufacture of products of unlimited length. In its simplest form the wheel has a single groove in its periphery which accepts the feedstock and transfers the material to the extrusion zone and die.

The diagram shows the configuration used for the production of most solid and hollow sections. A die chamber, carrying the appropriate die, is supported in a shoe. The die chamber incorporates an abutment that protrudes into the wheel groove. The force applied by the rotating wheel causes the feed material near the abutment to flow plastically into the die chamber and extrude through the die. Whilst the feedstock is usually in the form of rod, the process can also operate with material of any morphology provided that it can be fed into a suitably sized groove.
