In automotive manufacturing, wiring harnesses serve as a critical component of the electrical system, and their processing and packaging processes are vital for ensuring product quality and performance. Proper packaging not only protects automotive wiring harnesses from physical damage but also ensures their safety and reliability during transportation and storage. Below are key considerations regarding the packaging in the automotive wiring harness processing.

1. Selection of Packaging Materials:

1. Flame Resistance and Insulation Properties:

Packaging materials should possess excellent flame resistance to prevent potential fires under extreme conditions. Additionally, the materials should offer certain insulation properties to avoid short circuits between the wiring harness and external elements. Common packaging materials include flame-retardant corrugated sleeves and insulating plastic tapes.

2. Environmental Resistance:

Considering the various environmental conditions automotive wiring harnesses may face, such as high temperatures, low temperatures, and humidity, packaging materials should exhibit superior environmental resistance to ensure the wiring harness functions effectively under different conditions.

2. Packaging Layers and Void Ratio:

1. Number of packaging layers:

The number of packaging layers should not be excessive, generally no more than three layers, to reduce packaging costs and avoid resource waste caused by over-packaging. At the same time, multi-layer packaging should ensure tight adhesion between each layer to provide better protection.

2. Packaging Void Ratio:

The void space in packaging should not exceed 60% to ensure the wires are adequately secured and protected. Excessive void space may cause the wires to shift during transportation, increasing the risk of damage.

3. Packaging Cost vs. Sales Cost:

Packaging costs should be kept within a reasonable range, generally not exceeding 20% of the sales cost. This helps reduce production expenses and enhances the product's market competitiveness. Additionally, companies should choose suitable packaging materials and methods based on market demands and product characteristics to maximize cost-effectiveness.

4. Packaging Labels and Warning Information:

1. Packaging Labeling:

The packaging should clearly display the product name, specifications, quantity, production date, shelf life (if applicable), and manufacturer information. This information aids customers in identifying and tracing the product, ensuring traceability and safety.

2. Warning Information:

The packaging should include necessary warning messages such as "Handle with Care," "Keep Dry and Avoid Sunlight," etc., to alert relevant personnel about the transportation and storage conditions of the product. Warning information should be printed in bold and distinguishable from the background to ensure it is eye-catching and easy to read.

V. Key Points of Packaging Operation:

1. Organization and Securing:

Before packaging, the wiring harness should be organized to ensure the main trunk and branches are straightened and laid flat. Use zip ties, clips, and other fasteners to secure the wiring harness inside the packaging to prevent it from shaking or shifting during transportation.

2. Wrapping and Bandaging:

When wrapping and bundling wire harnesses with insulating tape or packaging tape, ensure that the wrapping is tight and even, with no loosening or slipping of the tape. Additionally, the bundling must comply with design requirements, avoiding exposed conductors or excessive tightness that could deform the wire harness.

3. Protection and Sealing:

For wiring harnesses that require moisture and dust protection, desiccants should be included inside the packaging or sealing treatment applied. This helps maintain the dryness and cleanliness of the wiring harnesses, preventing contamination or damage during storage and transportation.
