The Importance of Conductor Preheating in Wire and Cable Manufacturing

In the manufacturing of insulated wires and cables, numerous production issues can arise. These include moisture in the conductive fibers, which negatively impacts the adhesive properties of the wire insulation, leading to pinholes and bare patch faults. These faults increase waste materials, reduce profitability, and slow down output.

Quality, consistency, efficiency, and cost-effectiveness are critical for the success of any wire and cable manufacturer. The issues mentioned above can severely impact these factors.

Solution: ZUMBACH In-line Induction PREHEATER

The solution to these issues is remarkably simple with the ZUMBACH In-line Induction PREHEATER. Our PREHEATER heats the conductor to a target temperature, calculated using the resistance of the conductor material, the line speed, and the ambient temperature of the conductive material. This preheating process eliminates wire moisture and improves the quality and consistency of the adhered insulation. It also enhances stripping characteristics, preventing pinholes and bare patch faults.

Benefits of Wire Preheating:

• Higher Line Speeds: Achieved due to lower stress within the insulation materials.
• Faster Start-Up Times
• Improved Product Quality and Consistency: Better uniformity of the insulation material, ensuring longer-lasting products.
• Reduced Waste: Enhances productivity and profitability.

What’s not to like? Improved product quality. Improved productivity. Reduced waste.
