Extrusion Tools
Extrusion tools are used in plastic insulation and coating processes for electrical wires and cables, ensuring smooth and uniform coverings. Typically divided into inner and outer dies, the inner die can be made from materials such as diamond, tungsten carbide, or hardened steel. Weilly's diamond-core extrusion dies deliver superior wear resistance, precision, and durability, lasting much longer than conventional tungsten carbide dies—even under high-speed, continuous production conditions.
Weilly Diamond – Specialists in PCD-Based Extrusion Die Solutions
Weilly Diamond specializes in high-precision extrusion tools built for electrical and communication wire insulation. Our PCD-core inner dies offer superior wear resistance and extended tool life, while our custom multi-hole guide options cater to a variety of production needs.
From plastic-coated copper wire to aluminum insulation lines, our extrusion dies are optimized for performance, reliability, and efficiency in demanding applications.
Extrusion dies are used for plastic insulation and sheathing in wires and cables, primarily consisting of inner and outer dies. Common outer die materials include solid tungsten steel and fully hardened steel, while inner dies come in diamond-embedded, solid tungsten steel, tungsten steel-embedded, and fully hardened steel variants. WeiLi Diamond offers high-precision diamond-core extrusion inner dies. Leveraging diamond's exceptional wear resistance, these dies deliver significantly longer service life than tungsten steel extrusion inner dies, even under high-speed production conditions.
