INDUSTRY KNOWLEDGE

In modern industrial and digital infrastructure, Wire&Cable Jacket Sheath Extrusion Line as the "blood vessels" for transmitting power and information. The quality of their outer jacket sheath directly determines a cable's durability, safety, and signal integrity. Facing market demands for higher transmission speeds, harsher environmental adaptability, and more efficient production, jacket extrusion has become a core process in wire and cable manufacturing. Jiangsu Newtopp Precision Machinery Co., Ltd., deeply rooted in the high-end cable equipment field, designs its jacket extrusion lines specifically to address industry pain points. Through high-precision, intelligent, and high-stability design, these lines provide reliable manufacturing solutions for power, data, industrial, and new energy sectors.

1. Foundational Knowledge

Jacket extrusion is a critical process in wire and cable production. It involves uniformly coating a conductor or cable core with a polymer material (such as PVC, PE, TPU, fluoroplastics, etc.) to provide insulation, protection, and identification.

Key Concept Definition & Purpose Impact on Final Cable Performance
Extrusion Concentricity The uniformity of the jacket material around the cable core, usually expressed as a percentage. Concentricity >90% ensures uniform insulation/protection thickness, preventing uneven signal attenuation, decreased voltage resistance, or weak points in mechanical strength.
Outer Diameter (OD) Tolerance The allowable dimensional deviation range of the jacket's outer diameter, commonly expressed as ± millimeters. Tight tolerance (e.g., ±0.03mm) ensures dimensional consistency, facilitating subsequent connector assembly, conduit installation, and meeting high-end application specifications.
Temperature Control Precision The deviation between the actual temperature and the set temperature in various zones of the extruder. Precision control within ±1°C is fundamental for preventing material degradation, ensuring stable melt flow, and achieving a smooth appearance and consistent physical properties.
Screw Design The core component of the extruder, responsible for conveying, compressing, melting, and metering the polymer. Optimized design impacts output, melt quality, color change efficiency, and resistance to degradation, directly affecting production efficiency and material utilization.

Newtopp Product Link: Our jacket extrusion line ensures high concentricity and strict OD tolerance through optimized screw design and precise temperature control, laying the foundation for high-quality cable manufacturing.
