Abstract

The method is for stripping polyimide enamel from wire. It comprises heating the polyimide coated wire in air to 1550 - 1600 degrees F for a short The method is for stripping polyimide enamel from wire. It comprises heating the polyimide coated wire in air to 1550 - 1600 degrees F for a short period of time. The polyimide is converted from a clear, lasting, tough material to a dark colored, brittle material. During this operation, the copper wire is annealed. The annealing of the copper permits severe cold working without damage to the wire.

Stripping Polyimide Enamel from Wire

The method is for stripping polyimide enamel from wire. It comprises heating the polyimide coated wire in air to 1550 - 1600 degrees F for a short The method is for stripping polyimide enamel from wire. It comprises heating the polyimide coated wire in air to 1550 - 1600 degrees F for a short period of time. The polyimide is converted from a clear, lasting, tough material to a dark colored, brittle material. During this operation, the copper wire is annealed. The annealing of the copper permits severe cold working without damage to the wire. If the wire is then bent through a sharp radius of approximately six to ten times that of the wire, and then bent in an opposite direction, straightened and passed through a set of rubber wipers, the insulation is stripped without scoring or scratching the wire and with little or no change in the wire diameter. This method enables a satisfactory stripping of wire without consequential damage to the wire.
