What is Extrusion Die
Extrusion die is a kind of wire guide tool to extrude the insulating materials out of the extruding machine then form an uniform coating on the surface of the conductor to make it insulated from other materials.
Extrusion Dies in Different Materials
There are many materials can be used to make extrusion dies. Here introduce 3 main kinds as follows.
PCD Inserted in Steel BodyThis extrusion dies are made by PCD blanks tipped very closely to the end of the steel body to keep a great concentricity. Diameters are from 0.3mm to 2.5mm.
Tungsten Carbide Extrusion DiesTungsten carbide extrusion dies are made by only tungsten carbide with diameters of 0.5mm-13.0mm.
Hardened Steel Extrusion DiesHardened steel extrusion dies are made by heat treated hard steel with diameters 0.5mm-20.0mm.
Application of Extrusion Dies
Made by extrusion dies, extruded insulated wires and cables are widely used in many fields and industries.
Communication FieldExtrusion dies can be used to make communication wires and cable, coaxial cables, etc.
Energy FieldPower cables, such as plastic cables, and rubber cables can also be made by extrusion dies.
Other FieldsExtruded insulated cables made by extrusion dies are also used in transportation, medical care, security fields.
Great Concentricity
As an extrusion die, concentricity is the most important specification to ensure the conductor is in the middle of the insulation material. When make extrusion dies, HG pay much attention on controlling their concentricity to make sure your cables’ quality is superior.
Abrasive Resistant and Heat Resistant
Working circumstance of extrusion dies decide they must be heat resistant and abrasive resistant. Made by selected qualified raw materials, HG extrusion dies can bear high temperature and own a long working time to increase your cables’ production.
Accurate Roundness of Extrusion Dies
Roundness control of an extrusion die is also indispensable. Only a die with round enough hole can produce cables with a precise diameter. At the same time, reasonable specifications of the dies make you can use them in a high speed extrusion to improve production efficiency.
Besides tungsten carbide, PCD tipped, steel extrusion dies, there are also single crystal diamond tipped and alloy steel extrusion dies for your choice.
Commonly used insulation materials are polypropylene, polyethylene, cross-linked polyethylene and so on.
Every kind of extrusion dies have their own characteristics. Please tell us your wires or cables then we can recommend suitable dies accordingly.
First of all, we have stable suppliers of raw materials. Then inspect all the specifications, especially some important ones, say concentricity and roundness many times in the production process. Finally make finished dies inspection strictly.
If there is a drawing or sample, we can check if it can be made.
Generally speaking, they will be packed in plastic boxes and cartons. Customized packages are also available.
