About DIE MOLD

Purpose of Data Cable Die

• The die is a tool used during the extrusion process to shape the data cable. Extrusion involves forcing raw materials (such as copper wires, plastic insulation, and other components) through the die to create the final shape of the wire.
• The die determines the size, shape, and structure of the cable, ensuring that the insulation, conductors, and protective outer layers are uniform and meet design specifications.

2. Components of a Data Cable Die

• Extruder Die: This part of the die has a specifically designed opening through which the raw material is forced. It shapes the cable's core, insulation, or outer covering as the material is extruded.
• Material Feed: The die receives materials such as copper for conductors, insulation materials (PVC, PTFE , PE), and sometimes fillers or shields for added durability.
• Cooling System: After the extrusion, the material needs to cool down and solidify. The die may have built-in cooling channels or water sprays to ensure the correct temperature for the extrusion process.

3. Types of Dies Used in Cable Manufacturing

• Wire Drawing Die: Used to pull the copper wire to the desired thickness before it's coated with insulation.
• Extrusion Die: A die used for extruding insulation material around the wire. This is crucial for creating the proper coating around each individual conductor inside the data cable.
• Shielding Die: Some data cables (like coaxial cables) require additional shielding. This type of die helps to apply a metal shield (often copper or aluminum) around the wire to reduce electromagnetic interference (EMI).
• Jacketing Die: This die is used to apply the outer layer or jacket of the cable, ensuring it is durable, flexible, and resistant to environmental factors.

4. Die Materials

• Steel: The most common material for data cable dies is hardened steel because of its durability and resistance to wear.
• Tungsten Carbide: Used in high-precision or high-wear applications, such as for drawing fine wires.
