Wenzhou Dongyao Trading\u2019s main product, high-purity purple copper foil, is an industrial-grade electrolytic conductive copper material. It is produced using state-of-the-art high-purity cathode copper electrolysis. The entire process includes air-tight isolation to prevent oxidation. The finished product has a bright and smooth surface, free of oil stains, pinholes, scratches, and oxidation spots.<\/p>\n
This product\u2019s electrical and thermal conductivity efficiency far surpasses that of ordinary alloy copper materials. The material has excellent ductility, allowing for bending, stamping, bonding, and composite processing. There are no issues of cracking, powder shedding, or discoloration during the processing process. After thermal processing, the deformation is minimal, and it exhibits strong weldability and electroplating adhesion. It is suitable for automated continuous production lines.<\/p>\n
It can be adapted to various manufacturing processes, such as long-distance composite bonding, precision etching, conductive film coating, electromagnetic encapsulation, and more. It is widely used in scenarios like new energy batteries, electronic circuits, electromagnetic shielding, equipment heat dissipation, conductive connectors, and decorative copper plating. The roll material can be cut into any desired width. It supports both small batch samples and large-scale orders, significantly reducing customer material waste and the rate of rework due to processing errors.<\/p>\n
1. Exceptional conductivity: Copper has high purity, efficient electrical and thermal conductivity, low losses, and is suitable for high-precision electrical components.<\/p>\n
2. Excellent surface quality: Mirror-like finish with no impurities, uniform thickness, precise tolerances, and smooth, hairless patterns after etching.<\/p>\n
3. Stable deformation control: soft copper foil can be bent over 10,000 times without cracking. The thermal processing zone has a narrow heat-affected area, with no signs of backside burning or oxidation.<\/p>\n
4. Strong composite processing capabilities: Excellent adhesion, capable of being combined with PET, aluminum foil, and insulating films, resulting in a tight, non-separating bond.<\/p>\n
5. Long-lasting lifespan: An anti-oxidant coating is available, which prevents moisture and air from penetrating, ensuring that the material does not oxidize or discolor over time.<\/p>\n
6. Low operational threshold: No need for complex pre-processing. Cutting, stamping, and etching are simple and easy to operate, and they are environmentally friendly with no harmful by-products.<\/p>\n
1. Packaging and Transportation<\/p>\n
The product is packaged in an extra-thick standard export carton, with shock-absorbing foam insulation inside to protect the copper sheets from scratches and oxidation during long-distance sea transportation. Stable cross-border logistics are provided, and the entire logistics journey can be tracked.<\/p>\n
2. Samples and wholesale services<\/p>\n
Small items can be provided with free samples, and customers only bear the shipping costs. We support small batch trial orders and bulk wholesale orders. Direct factory sales with no intermediaries offer significant advantages for Southeast Asian distributors.<\/p>\n
3. After-sales support services.<\/p>\n
In cases where dimensional deviations, material inconsistencies, or other quality issues arise due to errors in our factory\u2019s processing, we offer free re-production and replacement. Our expert team provides comprehensive guidance on customizing drawings and is available to resolve any equipment assembly and compatibility challenges promptly.<\/p>\n
4. Qualification Certification and Payment Methods<\/p>\n
Accompanied by original factory material inspection reports and export environmental certification. Wire transfers, letters of credit, and local cross-border transfers are all possible. A deposit can be paid upfront to arrange production, and the remaining balance will be settled before shipment.<\/p>\n
