Packaging considerations for automotive wiring harness processing!

In automobile manufacturing, the wiring harness is an important part of the electrical system, and its processing and packaging process is crucial to ensure product quality and performance. Reasonable packaging can not only protect the automotive wiring harness from physical damage, but also ensure its safety and reliability during transportation and storage. The following are some key considerations for packaging during the processing of automotive wiring harnesses.

一. Selection of packaging materials:

1. Flame retardant and insulation properties:

The packaging material should have good flame retardant properties to prevent fire in extreme cases. At the same time, the material should have certain insulation properties to avoid short circuits between the wiring harness and the outside world. Common packaging materials include flame retardant corrugated sheaths, insulating plastic tapes, etc.

2. Environmental resistance:

Considering the various environmental conditions that automotive wiring harnesses may face, such as high temperature, low temperature, humidity, etc., the packaging material should have excellent environmental resistance to ensure that the wiring harness can work normally in different environments.

二. Packaging layers and void ratio:

1. Number of packaging layers:

The number of packaging layers should not be too many, generally not more than three layers, to reduce packaging costs and avoid waste of resources caused by excessive packaging. At the same time, multi-layer packaging should ensure that each layer fits tightly to provide better protection.

2. Packaging void ratio:

The packaging void ratio shall not be greater than 60% to ensure that the wiring harness is fully fixed and protected in the packaging. Excessive voids may cause the wiring harness to shake during transportation, increasing the risk of damage.

三. Packaging cost and sales cost:

Packaging cost should be controlled within a reasonable range, generally not exceeding 20% ​​of sales cost. This helps to reduce production costs and improve the market competitiveness of products. At the same time, enterprises should choose appropriate packaging materials and methods according to market demand and product characteristics to maximize cost-effectiveness.

四. Packaging label and warning information:

1. Packaging label:

The product name, specification, quantity, production date, shelf life (if applicable) and manufacturer information should be clearly marked on the packaging. This information helps customers identify and trace products and ensure product traceability and safety.

2. Warning information:

The packaging should contain necessary warning information, such as "handle with care", "moisture and sun protection", etc., to remind relevant personnel to pay attention to the transportation and storage conditions of the product. The warning information should be printed in bold and distinguished from the background to ensure that it is eye-catching and easy to read.

五. Key points of packaging operation:

1. Arrangement and fixation:

Before packaging, the wire harness should be arranged to ensure that the main line and branch line are straightened and laid. Use cable ties, buckles and other fasteners to fix the wire harness in the package to prevent it from shaking or shifting during transportation.

2. Wrapping and wrapping:

When using insulating tape or packaging tape to wrap and wrap the wire harness, ensure that the wrapping is tight and even, and there should be no loose or sliding of the tape. At the same time, the wrapping should meet the design requirements, and the core wire should not be exposed or the wrapping should be too tight to cause the wire harness to deform.

3. Protection and sealing:

For wire harnesses that need to be moisture-proof and dust-proof, desiccant should be added to the package or sealed. This helps to keep the wire harness dry and clean and avoid contamination or damage during storage and transportation.

Summary: The packaging link in the automotive wire harness processing process is of great significance to ensure product quality and performance. By selecting appropriate packaging materials, controlling packaging layers and void ratios, reasonably controlling packaging costs, clearly marking packaging logos and warning information, and strictly complying with packaging operation points, the safety and reliability of the wire harness during transportation and storage can be ensured. At the same time, these measures also help to improve the market competitiveness of products and meet customer needs.
