Application background At present, with the vigorous development of the new energy automobile industry, the performance requirements for key components are becoming more stringent. Silicone rubber flat cable plays a pivotal role as an important part of connecting battery pack and management system, drive motor and controller. A well-known new energy vehicle manufacturer, in its new model research and development, selected silicone rubber flat cable.   Reason for use High temperature resistance: new energy vehicles will generate a lot of heat during operation and charging, and ordinary cables are easy to age at high temperatures, affecting electrical performance. Flat silicone rubber cables maintain stable electrical performance in high temperature environments, ensuring that power transmission is not affected when the vehicle is driving at high speeds or charging for a long time. Low temperature resistance: In cold areas, ordinary cables may become brittle and fail to work normally. Silicone rubber flat cable has good low temperature resistance, so that the vehicle can start and run normally in cold areas. Corrosion resistance: The vehicle operating environment is complex, the corrosion resistance of silicone rubber material, effectively resist the erosion of the cable in the harsh environment such as humidity, acid and alkali, and greatly improve the safety and reliability of the vehicle.   Problems encountered Limited installation space: The compact interior structure of the car leaves very limited space for cable wiring, and traditional circular cables are difficult to meet the layout needs. Electromagnetic interference problem: there are many electronic devices inside new energy vehicles, and the complex electromagnetic environment is easy to interfere with the cable transmission signal.   Solution Optimized flat design: The section shape and size of the silicone rubber flat cable are optimized to save the installation space to the greatest extent under the premise of meeting the electrical performance. Through accurate calculation and many tests, the optimal flat proportion is determined to ensure that the cable can be flexibly routed in a small space. Add a shield layer: Add a metal shield layer on the outer layer of the cable to effectively block external electromagnetic interference and ensure the stability of signal transmission. At the same time, the grounding mode of the shielding layer is optimized to further improve the anti-interference effect.   Achievement After actual road testing and user feedback, the electric system of this model runs stably in various complex environments, and there is no fault caused by cable problems. Not only solves the problem of installation space, but also improves the reliability of the vehicle in a complex electromagnetic environment, which effectively proves the reliability and applicability of silicone rubber flat cable in the field of new energy vehicles.

In the mass production of a customized rubber seal ring, we encountered a sudden decline in the product pass rate, and now the problems and solutions are shared as follows:   Problems that arise: Lack of glue: some products appear concave and incomplete areas on the surface, which seriously affects the sealing of the product. This is due to the complexity of the mold cavity, the rubber material encountered resistance during the flow process, and the cavity could not be completely filled. Bubbles: there are a large number of tiny bubbles inside the finished product, which greatly reduces the physical properties of rubber products and reduces the tensile strength. The reason is that when mixing rubber, the water is not fully removed, and the water vaporizes to form bubbles when heating the die; In addition, the amount of glue filling is too much, and the gas can not be discharged smoothly when pressing the mold, which will also cause bubbles. Excessive flash: excess rubber sheets appear on the edge of the product, which not only affects the appearance, but also increases the workload and cost of the subsequent trimming process. The main reason is that the mold closing precision is not enough, the gap is too large, resulting in the rubber material overflow under high pressure; There is also the molding pressure is too high, beyond the mold design to withstand the range, prompting the rubber material extrusion to form a flash. Solution: For the problem of lack of glue: optimize the mold design, polish the flow path of the cavity, and reduce the flow resistance of the rubber material; At the same time, the molding temperature is appropriately increased, the viscosity of the rubber material is reduced, and the fluidity is enhanced to ensure that the rubber material can fully fill the mold cavity. For the bubble problem: strictly control the drying treatment of raw materials, increase the drying process before mixing to ensure that the moisture content is lower than the standard value; And adjust the filling amount of rubber material, according to the volume of the mold cavity, accurately calculate the filling amount, reserve a certain gas discharge space, install the exhaust device, auxiliary gas discharge. Solve the problem of excessive flash: First of all, repair the mold, adjust the accuracy of the mold, repair the wear part, reduce the mold gap; Secondly, the reasonable molding pressure is re-determined through the test to avoid excessive pressure resulting in the overflow of the rubber material. Through this series of improvement measures, the pass rate of our customized rubber products has been significantly improved, and the subsequent production can also be smoothly carried out, effectively reducing the cost, ensuring the quality of the products, and being well received by customers.
