High-Performance Slitting, Laminating, and Coating Equipment Empowers Cable Shielding Material Manufacturing
Cable Shielding — The “Guardian” of Modern Communication and Power Transmission
In today’s world driven by data and electricity, the lossless transmission of information and efficient delivery of energy are paramount. The cable shielding layer—a critical material wrapped around the core of a cable—is the unsung hero ensuring this goal is achieved. By absorbing or reflecting electromagnetic interference (EMI) and radio-frequency interference (RFI), it acts as a barrier, protecting internal signals from external disturbances while preventing internal signal leakage. This safeguards the integrity, security, and stability of data transmission.
From 5G base stations and data centers to new energy vehicles and industrial automation, high-performance shielded cables serve as the blood vessels and nerves of these systems. Leveraging its leading slitting, laminating, and coating technologies, Tengda Machinery is deeply involved in the core processes of manufacturing these high-end shielding materials, providing reliable upstream material processing solutions for cable manufacturers.
Meeting Stringent Industry Demands with Precision Processing Technology
The production of cable shielding materials places extreme demands on equipment precision, stability, and tension control. Our equipment series, specifically designed for functional materials, can efficiently process aluminum foil, copper foil, polyester film (PET), polyimide (PI), as well as various non-woven fabrics and composite materials.
Coating Machines: Applying Functional “Clothing” to Materials
Coating is one of the core processes in manufacturing shielding materials. Our high-precision coating machines enable ultra-thin, uniform functional coatings on various substrates.
Application Descriptions:
Conductive Coating Application: Uniformly coating conductive inks or silver paste on PET films to create conductive layers with electromagnetic shielding functionality, used in producing lightweight, flexible shielding materials.
Adhesive Coating: Applying high-performance adhesives evenly on one or both sides of shielding foils (e.g., aluminum foil). This is a critical step in producing foil-based shielding tapes and composite shielding materials. The uniformity of the coating directly determines the consistency and performance of the final shielded cable.
Laminating Machines: Building Multi-Layer Material “Armor”
A single shielding layer often needs to be combined with other materials to enhance mechanical strength, provide insulation, or facilitate installation. Our laminating machines perfectly bond different materials into one.
Application Descriptions:
Foil-Film Lamination: Dry or solvent-free lamination of aluminum/copper foil with PET film to create composite shielding tapes with excellent shielding performance, flexibility, and mechanical strength.
Non-Woven Fabric Lamination: Combining metal foil with non-woven materials to form shielding layers wrapped around cable cores. This provides electromagnetic shielding while offering cushioning, filling, and wrapping functions, widely used in automotive wiring harnesses and data center cables.
Slitting Machines: Ensuring the Perfect “Form” of the Final Product
Master rolls after coating and laminating must be slit into specific widths required by customers. The quality of slitting determines the processing efficiency of shielding materials in cable production lines.
Application Descriptions:
Slitting wide master rolls into dozens of narrow rolls of different widths for manufacturing wires of shielding braided nets or spiral-wound shielding tapes.
Extremely high requirements for edge quality: must be burr-free and without flanging. Any minor flaw could cause breakage during high-speed wrapping or puncture the cable insulation layer, leading to short circuits.
