Melt mold casting

One is to make the wax into a mold, coat it with several layers of refractory paint to make a mold shell, and then heat the mold, so that the mold melt, flow out, and baked into a certain strength mold, and then poured, shell and get a casting method. Process features: take the melting pattern as the starting mode. The precision of casting is high, and it is a method of little cutting. Its equipment is simple and production quantity is not restricted. It is mainly used for mass production and mass production. The drawback is that the process is complex and the production cycle is long.

Pressure casting - a casting process in which molten metal is rapidly pressed into the cavity of a metal mold under high pressure and solidified under pressure to obtain a casting. Process characteristics: High speed and high pressure were added to the metal mold casting to enhance the metal fluidity, which was mainly used in the batch production of non-ferrous alloy (such as aluminum, copper, magnesium, etc.) precision castings.

Centrifugal casting - a casting process in which molten metal is poured into a high-speed rotating mold to solidify liquid metal under centrifugal force to obtain a casting. Process features: compact structure, good casting quality. It is used to produce hollow castings.

      China's shortcuts in automobile manufacturing industry
      Over the past nine years, China has become the world's largest automobile market and producer, with annual production and sales exceeding 25 million vehicles. China's automotive industry has also been the world's largest automotive industry in just a few years, driven by the huge domestic demand of the Chinese market. But there is not a strong enough component system to support the development of China's automobile industry. In March this year, the 2017 Top 100 list of global auto parts suppliers was officially unveiled. Unsurprisingly, Germany's Bosch Group continued to rank first with more than $46 billion in revenue, while German gearbox supplier Zeiff rose to second. From the third to the tenth ranking of parts companies are Magna, electronics, mainland, Aixin, modern Mobius, Virginia, Lear.
      In this ranking, China's highest ranking of parts companies is Yanfeng automotive interior system, followed by CITIC Deka ranked 71. And the selected parts enterprises are mainly single components. Feilong Jiangli supply water pumps for car plants.
      In contrast, there is no comprehensive automobile parts supplier in China's automobile industry.

      Hydrogen induced wear: hydrogen is released during the friction due to mechanical and chemical action. Hydrogen diffuses into the deformed layer of metal surface, causing a large number of crack sources in the deformed layer. The generation and development of cracks make the surface material fall off, which is called hydrogen-induced wear. Oxygen may come from material itself or environmental medium, such as lubricating oil and water.

      The mechanism of cavitation is surface fatigue damage caused by impact force, but the chemical and electrochemical action of liquid and abrasive inclusion in liquid may accelerate cavitation damage. For example, the cylinder liner cavitation is caused by the action of piston lateral thrust because the combustion pressure in cylinder varies with crankshaft angle. The elastic deformation and high-frequency vibration of bubbles produce great impact force (tens or even tens of thousands of high pressure) and high temperature (hundreds of degrees) at the instant of collapse, and the collapse speed can reach 250m/s.
      Feilong jiangli will update analysis of more auto parts failure models.

      Automotive engine bracket
      Automobile engine bracket is a safe and functional part of powertrain mounting system. It must satisfy the strength of automobile under various driving conditions and the restraint mode of mounting bracket has a great influence on the noise inside the vehicle. If the design is unreasonable, the natural frequency of the mounting bracket I is too low and in the range of engine operating speed, the mounting bracket will produce resonance, which will increase the noise inside the vehicle. Therefore, modal is one of the important design indexes of mounting bracket. Taking the four-cylinder engine of passenger car as an example, according to the resonance theory, it is required that the natural frequency of the engine mounting bracket should be greater than 500 Hz, and the lowest should be greater than 400 Hz. In fact, due to the limitation of the layout space, the above requirements can not be met. The first order natural frequency should be increased as much as possible. Feilong Jiangli,40 years specialize in engine bracket, through the optimization design and modal analysis of the suspension bracket practice, summed up to improve the modal method, to provide a theoretical basis for design.

      Shock absorber
      In order to accelerate the vibration attenuation of the frame and body and improve the ride comfort of the vehicle, vibration absorbers are installed in the suspension system of most automobiles. Both the shock absorber and the elastic element are installed in parallel.
      Hydraulic shock absorbers are widely used in vehicle suspension systems. The principle of the hydraulic shock absorber is that the oil in the shock absorber shell flows repeatedly from one cavity to another through some narrow cavities when the piston moves in the cylinder cylinder when the driver and the bridge move reciprocating relative to each other. At this point, the friction between the hole wall and the oil and the friction between the liquid molecules form a damping force to the vibration, so that the vibration energy of the body and the frame can be converted into heat energy, which is absorbed by the oil and shock absorber shell, and then dispersed into the air. The damping force of the shock absorber increases or decreases with the relative velocity of the frame and the axle, and is related to the viscosity of the oil. Therefore, the viscosity of the oil used in the shock absorber is required to be as little as possible affected by temperature changes: and has the properties of anti-vaporization, anti-oxidation and non-corrosive to various metal and non-metal parts.
