Coolervie supplies wire drawing extrusion tips and dies for precision insulation extrusion in wire and cable manufacturing. Designed to guide the conductor and control polymer flow through the extrusion tooling, these components help support consistent insulation coverage, wall thickness, and conductor-to-insulation concentricity.
Available in single crystal diamond, polycrystalline diamond, tungsten carbide, and tool steel, extrusion tips and dies can be selected according to conductor size, insulation material, tooling dimensions, and production requirements. Contact Coolervie to discuss your application and request a quotation.

Applications
Coolervie extrusion tips and dies are used in the production of precision-insulated wire and cable. The tip guides the conductor through the extrusion head, while the die shapes the extruded insulation layer. Proper tooling geometry and alignment help maintain conductor centering, consistent insulation wall thickness, and dimensional stability.
These tools are suitable for applications where insulation uniformity and reliable electrical performance are important, including communication cables, electronic wires, and other insulated conductors. The appropriate tooling configuration depends on conductor dimensions, insulation material, cable construction, and extrusion conditions.
Typical Markets
Coolervie extrusion tips and dies serve wire and cable manufacturers producing:
Telecommunication Cables: Insulated conductors used in telephone and data transmission cables.
Electronic Wires and Cables: Precision-insulated conductors for electronic equipment and electrical assemblies.
Data Communication Cables: Cable constructions where consistent insulation geometry and conductor positioning are important.
ADVANTAGES
Precision Concentricity
Accurate tip and die geometry helps maintain conductor centering and consistent insulation thickness. A concentricity specification of 0.0002 in (0.005 mm) TIR may be stated where it is verified for the applicable tooling type and supported by inspection records.
Quality Inspection and Documentation
Each product is individually packaged and supplied with a quality inspection certificate to support product identification and incoming quality checks.
Custom-Made to Your Specifications
Extrusion tips and dies can be manufactured to agreed dimensional and material requirements. Provide your technical drawing, conductor dimensions, and insulation specifications to help determine the appropriate tooling configuration.
Stock Availability and Delivery Support
Selected standard styles and sizes may be available from stock. Contact Coolervie to confirm current availability, production lead time, and shipping arrangements for your order.
To help us evaluate your requirements, please provide the conductor diameter, insulation material, required insulation dimensions, tooling material preference, and technical drawing if available.
