Comparative HS code duty analysis

Engine crankshaft recasting: the newly upgraded power source is Comparative HS code duty analysisa key component of the internal combustion engine. The engine crankshaft is the core component that converts the internal combustion explosive vibration energy of the engine into the kinetic energy of the automobile hub. In automobiles, the importance of engine crankshaft is self-evident, and its manufacturing process and material selection are also one of the important criteria for measuring the overall quality of the engine. With the development of science and technology and the continuous updating of materials, today's engine crankshaft is no longer the same as it used to be.In a single and simple form, they are more complex, precise, light and wear-resistant, and the perfect integration of high temperature, high pressure resistance and other characteristics. This article will introduce readers to the new upgrade of engine crankshaft recasting and its impact on the improvement of the performance of the whole vehicle. 1. The limitation of traditional manufacturing methods. In the past, most of the crankshaft frames of modified models were used as prototypes, and parts such as crankshafts were updated by the owner's own assembly and machining. Although the cost of this method is low, it has many disadvantages in the manufacturing process, such as not meeting the precision size required by the design, the durability of the material is constrained, and even the choice of material is not satisfactory. Moreover, the crankshaft is prone to brittle cracking, fracture and other phenomena under long-term high temperature and high pressure, which causes unpredictable dangers.Two. The application of the new manufacturing process is different from the traditional method. Now some advanced production workshops produce more high-quality and more precise engine crankshafts through high-precision numerical control equipment, material technology and design technology. Adopting the combination of casting, forging, seamless steel pipe and other processes, through fine precision calibration and relying on complex processing technology, on the basis of ensuring the stability and corrosion resistance of the product, the hardness, strength, bending resistance and other important indicators of the workpiece are significantly improved. At the same time, this high-precision and high-tech new production method is more efficient and stable in quality, which can meet the production needs of different models in the market and meet the production capacity requirements of tens of millions and hundreds of millions of pieces. 3. The application of new materials is in terms of materials. New high-performance materials such as aviation titanium alloy, ultra-strong high-speed steel, etc. have also become the latest choice to replace traditional automobile crankshafts.These high-performance materials have the characteristics of corrosion resistance, high hardness and high temperature resistance, which has an enhancing effect on solving the problem of component failure caused by temperature and environment of traditional automobile crankshafts. Especially for the crankshaft manufacturing of high-end models, the use of high-end aviation titanium alloy materials has a longer life and more stable performance, which is of great benefit to the improvement of fuel efficiency, safety and emission performance of the whole vehicle. Four. For the improvement of the performance of the whole vehicle, with the help of modern technology and the use of advanced materials, the power and torque of the vehicle have been further improved under the engine that is more advanced, more environmentally friendly, fuel-efficient and optimized. The initial power output is more stable at low speed and during the start-up process, the engine speed changes more naturally when accelerating, and the speed rises faster and smoother. At the same time, due to the crankshaft'sImproved, the performance of the whole car in terms of shock absorption, balance and other aspects has also been upgraded, bringing customers a more comfortable and safer driving experience. Summary: Now in the whole development process of the automobile manufacturing industry, the recasting of the key component of the engine crankshaft shows the superior application of new technologies in the automobile industry and the infinite possibility of upgrading the automobile industry. We believe that in the process of continuous innovation, the new engine crankshaft will better adapt to the requirements of the future automobile market, achieve lower fuel consumption, longer service life and higher performance, and bring a more convenient, relaxed and comfortable travel experience to car owners.
