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.

The phenomenon that two objects move relative to each other to produce motion resistance between their contact surfaces is called friction, which is called friction. The existence of friction not only increases the power consumption, but also causes the wear of parts' contact surfaces. Therefore, lubricating oil is usually used between the relative moving surfaces of automobile parts to reduce friction. Failure of automotive parts 75% is caused by friction.
Friction can be divided into dry friction, liquid friction, boundary friction and mixed friction according to the lubrication state of the parts.
(1) dry friction
The friction between the frictional surfaces without any lubricating medium is called dry friction.
When the parts are in the state of dry friction, the surface of the parts is abraded sharply, so the surface of the moving parts of the automobile should avoid the occurrence of dry friction as far as possible.
Dry friction and boundary friction are the main friction between the upper part of cylinder wall and piston ring. Dry friction will occur when the journal and bearing are subjected to impact load in the working process.
(2) liquid friction
Two the friction of the friction surface when the lubricant is completely separated is called liquid friction.
In liquid friction, the two friction surfaces are completely separated by a layer of lubricating oil film with a thickness of 1.5-2.0um, which avoids direct contact between the working surfaces of the two parts. Friction only occurs between the lubricating fluid molecules, so the friction resistance is very small, and the wear of the parts is very slight.
Most of the relative motion parts of a car are carried out under the condition of liquid friction (for example, crankshaft and bearing).
(3) boundary friction
Two friction surface separated by a very thin boundary film is called boundary friction.
The oil film thickness is usually below 0.1um. Friction only occurs between the outer molecules of the boundary film, reducing the friction and wear of the parts. But its thickness is very small, and it is easy to be destroyed by impact and high temperature, so it is not as reliable as liquid friction.
For example: between cylinder wall and piston ring; if the work crankshaft and journal between the insufficient supply of lubricant, easy to produce boundary friction.
(4) Mixed friction
The friction between two friction surfaces in the presence of dry friction, liquid friction and boundary friction is called mixed friction.
In the actual working state, the parts usually work under the mixed friction state, and the friction state varies with the working conditions.

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.

Automobile parts refer to the components of each unit of the automobile and all consumable materials serving the automobile. They can be divided into automobile parts, Automobile standard parts and automobile materials. The following is a detailed introduction.
（1）Auto parts are divided into parts, assemblies, component, and body panels.
Parts: the basic manufacturing unit of a car. It is an integral part that can no longer be disassembled. Such as: piston ring, piston, valve, impeller and so on.
Assembly: a combination consisting of more than two parts and acting as a single part. For example, a connecting rod with a cover, a pair of bearing shells, and a cylinder head with a valve guide.
Component: a combination consisting of several parts or assemblies, but can not function independently. For example, transmission cover, cooler cover, automobile steering connector, water pump and so on. Sometimes it is also called "half assembly".
Body panels: formed by sheet metal stamping, welding, and covering automotive body parts such as: radiator cover, leaf plate, etc.
(2) automotive standard parts
Designed and manufactured according to the national standards, the same parts are unified in shape, size, tolerance, technical requirements, and can be used in a variety of instruments and equipment, and interchangeable parts are suitable for automotive standard parts such as bolts, gaskets, pins, keys, etc.
(3) automotive materials
Automobile operating materials, such as various oils, solutions, automotive tires, accumulators, standard bearings (non-special), etc.
Most of the products produced by non-automotive industry and used by automobiles, generally not included in the catalogue of various types of automotive accessories, also known as "horizontal products".
