The automotive wiring harness functionally divides the power harness, the control harness for signal transmission, and the brake control harness. A power line is a thick wire that carries a large current.
The material requirements for the automotive sector are relatively strict, especially for wire harnesses. We all know that the temperature around the car engine is very high, and there are many corrosive gases and liquids, which require high temperature resistance, oil resistance, vibration resistance and friction resistance. It is more demanding than the general electronic harness, and the engine system, and the wiring harness of the brake system can not have any quality problems.
The wiring harness of the car trunk should be made of cold elastic wire to ensure flexibility under low temperature conditions. For weak signal sensors, shielded wires should be used. The wire speed assembly of the automobile brake system must have a high temperature resistance of more than 150-200 ° C. The outer protective insulation layer is hard and wear-resistant.
The wire processing process uses its polyethylene material and has excellent rheological properties. Generally, good polyethylene has a uniform and stable melting index, which is suitable for different beam diameters during use, so that it can be effective. A certain extrusion speed is achieved, and the extrusion flow rate is effectively stabilized during use, so that the geometric shape and appearance integrity of the product can be effectively ensured.
The quality of the wire harness processing material will directly affect whether the product of the car wire harness meets its performance requirements. The quality of the wire harness material also directly affects the performance and service life of the automotive wiring harness. When choosing a wire harness manufacturer, you must not use your quotation alone to decide whether or not to cooperate. The price is determined by the value, and the high-priced wire harness is more quality guaranteed. Take the wire harness terminal as an example. The standard automotive wiring harness is made of bronze and brass, and it indicates that there is plating, which is more expensive, and the price of secondary processed copper on the market is cheaper, but the performance will be much worse. The two kinds of materials, the car harness made will not have a clear difference in appearance, but the price is very different.
The selection of materials must be controlled, and the processing technology cannot be relaxed. All aspects of production, good appearance inspection and performance testing, effective analysis of the status quo, effectively ensure that wire harness processing meets quality control standards. Control the production quality from the source, improve the failure rate of wire harness processing, and do a truly high-efficiency, high-quality production.
