Stripping Die

A Stripping Die is a precision tool used in wire and cable manufacturing to cleanly and efficiently remove insulation, enamel, oxide layers, or other surface coatings from metal wire—without damaging the conductive core. It serves as a critical component in processes requiring bare, clean wire for subsequent operations such as drawing, welding, plating, bonding, or termination.

Our Stripping Dies are engineered for reliability and consistency, fabricated from wear-resistant materials such as tungsten carbide, tool steel, or diamond-coated substrates, depending on the application’s abrasiveness and required service life. The die features precisely machined internal profiles—such as sharp-edged blades, tapered bores, or multi-point cutting geometries—that shear or scrape away the outer layer as the wire passes through under controlled tension.

Key Features:

High Precision: Maintains tight concentricity and uniform strip length or depth.

Material Versatility: Effective on enameled copper, magnet wire, PVC-insulated conductors, anodized aluminum, and oxidized stainless steel.

Custom Configurations: Available in single-hole or multi-hole designs, with adjustable stripping depths or segmented inserts for different wire gauges.

Long Service Life: Carbide or diamond-enhanced edges resist wear during high-speed, continuous operation.

Clean Removal: Minimizes nicks, scratches, or deformation of the base metal.

Common Applications:

Magnet wire processing (removing polyurethane, polyester, or polyimide enamel)

Recycling of insulated copper wire

Preparation of fine wires for semiconductor bonding or medical leads

Surface cleaning prior to electroplating or cold drawing

Automotive and aerospace wiring harness production

Designed in close collaboration with clients to match specific wire diameters, coating types, line speeds, and automation requirements, our Stripping Dies integrate seamlessly into both manual and fully automated production lines. Backed by metrology-grade quality control and material traceability, they ensure consistent performance, reduced downtime, and superior end-product quality.
