• Automotive Heat-Exposed Cable Routing
Helps protect cables near engine-compartment heat sources and hot components from radiant heat exposure.
• Industrial Equipment Wiring
Adds thermal and external mechanical protection for wiring near heat-generating machinery components.
• Flexible Ventilation Ducting
May be used in compatible air-guidance routes subject to airflow, temperature and installation requirements.
• Thermal Equipment Connections
Supports flexible routing around equipment structures and obstructions.
• Industrial Pipeline Protection
External protective covering for compatible industrial lines exposed to heat and routine environmental contact.
Measure the maximum outside diameter of the cable, hose or pipeline, including any section that must pass through the wire loom during installation. Select an inside diameter with enough assembly clearance without excessive looseness.
Check operating temperature, distance from heat sources, routing length, bend radius and exposure to oil or moisture. For ventilation or flow-guidance applications, evaluate airflow, pressure conditions and connection methods. Avoid excessive compression, sharp bends and damage to the laminated structure. Validate critical assemblies under actual operating conditions.
• Sizes & Dimensions - Standard inside diameters of 8–120 mm are available; special sizes may be reviewed for specific projects.
• Cut Lengths - Standard supply is 1 m per piece. Alternative lengths are subject to production feasibility and order quantity.
• Construction Requirements - Wall thickness, flexibility and tube construction may be reviewed for project-specific requirements, subject to technical confirmation.
• Packaging - Product labels, quantity-based packing and customized packaging can be arranged according to order requirements.
• Raw Material Verification - Aluminum foil and fiberglass are checked against approved material and construction requirements.
• Lamination Integrity Control - Composite-layer bonding is checked for delamination, localized separation and material defects.
• Dimensional Inspection - Inside diameter, wall thickness and cut length are checked against approved specifications.
• Surface and Workmanship Inspection - Finished products are checked for damage, excessive wrinkles, contamination, delamination and end defects.
• Final Inspection and Traceability - Part number, dimensions, quantity, packaging and labels are checked before shipment, with batch records maintained as required.
Frequently Asked Questions
