MARKET PATTERN OF ALUMINUM ALLOY DIE CASTING IN CHINA

The global die casting manufacturing center is transferred to the mainland of China. China's precision die casting enterprises are mainly distributed in Guangdong, Jiangsu, Zhejiang, and other places. Most of the large-scale and specialized enterprises are concentrated in the Pearl River Delta and the Yangtze River Delta. Due to the dominant position of Asia, especially China, in market demand, raw material supply, labor resources, industrial chain supporting, policy support, and the rapid development of China's automobile industry, since the 21st century, the global die casting production has shown a trend of transfer to Asia, especially to the mainland of China, which is still continuing. The expansion of market scale and the entry of international excellent enterprises have promoted the technical level and management level of domestic die casting manufacturers, and further promoted the development of the industry. China has formed the Yangtze River Delta, Pearl River Delta, northeast three provinces, southwest region and other pressure casting industrial clusters, of which the Yangtze River Delta and the Pearl River Delta are the most prominent. The two regions have an active economy, developed supporting industries and obvious regional advantages.

 Advantages of Aluminium Parts in Automobile

Under the premise of ensuring vehicle strength and safety performance, vehicle lightweight can improve vehicle power, reduce fuel consumption and exhaust pollution by reducing vehicle quality. Reducing the mass of different parts such as body, interior, and exterior decoration, power system and so on will help to reduce the energy consumption in the process of driving. Aluminium parts in automobile is light, recyclable and easy to form, so it is widely used in the automobile body and parts. In theory, automotive aluminum parts can reduce the weight of steel cars by as much as30% - 40%, of which aluminum engine can reduce 30%, the aluminum radiator is 20% - 40% lighter than copper, the all-aluminum body is 40% lighter than steel, and aluminum hub of the automobile can reduce 30%. Therefore, aluminum alloy material is an ideal material for automobile lighting.

 Reducing the vehicle weight can reduce the engine load, improve the driving performance of the vehicle, effectively reduce the braking distance, make the steering and bending process more flexible so that the vehicle is more stable, and the aluminum alloy structure can absorb and disperse more energy when impacted, so it is more comfortable and safe. As a result, in the next decade, the aluminum penetration rate of all major parts of the car will be significantly increased, and the penetration rate of the aluminum engine hood is expected to increase from48% in 2015 will increase to 85% in 2025, and the penetration rate of aluminum doors will increase from 6% in 2015 to 46% in 2025. Specifically reflected in the average aluminum consumption per vehicle in North America in 1975, the average aluminum consumption per vehicle in North America was 38kg, which increased to 180kg in 2015. In 40 years, the aluminum consumption per vehicle in North America continued to increase, with a compound growth rate of 4%. It is estimated that China will achieve 190kg / vehicle aluminum consumption in 2020, which is in line with North America, with a corresponding market space of about 152 billion yuan.

 The concentration of the die-casting industry in China is relatively low. There are about there are more than 12000 enterprises, of which more than 70% are die-casting enterprises. The enterprises are mainly distributed in Guangdong, Jiangsu, Chongqing, and other places. Most of the large-scale and specialized enterprises are concentrated in the Pearl River Delta and the Yangtze River Delta, and the proportion of large-scale die-casting enterprises is only about 10%. There are two main types of domestic enterprises with large production scale of automobile die-casting, one is the supporting enterprise of automobile field, which is subordinate to the group company of downstream industry; the other is the independent automobile precision die casting production enterprise, which is specialized in the production of automotive casting components, and has established a relatively stable long-term cooperation relationship with downstream customers.

HOW TO AVOID THE ALUMINUM DIE-CASTING GETS BLACKENED AFTER SHOT BLASTING?

The reasons for blackened aluminum die casting parts after shot blasting are:

1. The dust removal is not done in the equipment during shot blasting;

2. There are oil stains, mold release and moisture on the casting surface;

3. Stainless steel pellets are not pure enough.

 To prevent the aluminum die casting parts from blackening after shot blasting, here is some suggestion:

1. The shot blasting equipment must have a relatively complete automatic dust removal effect;

2. The surface of the casting should not be contaminated with oil, mold release agent, moisture or other impurities. If necessary, the casting should be washed and dried before shot blasting;

3. Purchase pure steel shots, if necessary, add 10 ~ 30% aluminum shots to increase the whiteness after shot blasting. The specific amount depends on the requirement of the parts.

HEAT SINK HOUSING

The heat sink enclosure uses aluminum with a high thermal conductivity as the main body of the heat sink, which has the advantages of light weight, corrosion resistance, strong thermal conductivity, non-magnetic and strong plasticity. Heat sink enclosure can be customized according to customer drawings.

 Overview of aluminum heat sink enclosure

Aluminum is light in weight and easy to manufacture. Aluminum alloy is the most common radiator material. The cost of aluminum is lower than that of copper and has high performance-to-price ratio, so it is an ideal choice for most radiators. Its heat transfer capacity, or thermal conductivity, is about half that of copper. This limits the distance at which heat moves and conducts from the heat source in the radiator base. The radiator is designed to maximize the surface area in contact with the coolant.

FRICTION WELDING

Friction welding overview

Friction welding is a pressure welding method that uses the heat generated by the relative frictional movement of the weldment to achieve reliable connection of materials.

The welding process is under the effect of pressure, the friction between the materials to be welded increases the temperature of the interface and its vicinity and reaches in the thermoplastic state, with the action of upsetting force, the interface oxide film is broken, the material undergoes plastic deformation and flow, and the joint is formed by the interface element diffusion and recrystallization metallurgical reaction.

EMP Tech Co., Ltd, offering professional friction welding services, can finish many kinds of friction welding, including the continuous drive friction welding, rotational friction welding and orbital friction welding, etc..

 Friction welding aluminum

The surface temperature of friction welding is the temperature of the heat source of friction welding, which will directly affect the heating temperature and temperature distribution of the joint and the deformation and diffusion of the joint metal. In the process of friction heating, the friction surface can also adjust the friction heating power through the influence of the friction coefficient, so that the heating power and the temperature of the heat source are in balance. Welding test and production practice show that when the diameter of the workpiece increases, the rotation number increases and the friction pressure increases, the temperature of the friction welding surface increases. Otherwise, the surface temperature of friction welding will be reduced.

 Friction welding services overview

Heating deforms the material, and the rotating tool stirs the material at the weld. In this way, friction welding technology creates a uniform structure with excellent performance. The whole process is emission-free. When welding must be very tight, friction welding is the preferred method. It can connect the workpiece with repeatable pressure and medium seal. Friction welding can be optimized and integrated into industrial batch production. The result is top quality that is easy to copy.

As a machinery parts manufacturer, we provide various products and services in this area, and actually friction welding services and production, continuous drive friction welding, phase-controlled friction welding, inertial friction welding and friction stir welding are more common used.

 Advantages of friction welding services

Durable, medium-sealed and pressure-sealed welds.

Height, repeatable seam quality.

Low warping joint.

No pores or hot cracks.

No exhaust emissions, no shielding gas, powder, welding wire and other auxiliary materials.

In actual friction welding services and production, continuous drive friction welding, phase-controlled friction welding, inertial friction welding and friction stir welding are more common.

Friction welding machine is mainly used for welding of medium-sized shaft parts. It can weld a wide range of metals, and has the characteristics of stable performance, high production efficiency and low energy consumption, which is important for friction welding companies.

 Orbital friction welding

Rail friction welding is similar to rotary friction welding, but the two welding parts of rail friction welding rotate in the same direction and at the same speed,with axes offset up to 3 mm. At the end of the welding, the two parts return to the common shaft, the relative motion ends, and the welding relay remains intact or increases. Rail friction welding has the advantage of uniform surface velocity in the whole contact zone. You can connect non-circular components and multiple individual parts in a friction welding sequence. Although rail friction welding has been demonstrated in many materials and joint configurations, it is rarely used in industry.

Overview of Cylinder Head Cover

There are  three types of cylinder heads include flathead, overhead valve and overhead camshaft cylinder heads, each of which can be made of cast-iron or aluminum material, depending upon the specific system in which they are being used in. Our Cylinder Head Cover is made of aluminum alloy. In general, aluminum alloy is lighter and has stronger heat dissipation potential than any other material. Meanwhile, Why choose aluminum alloy to be the material of cylinder head cover? Not only aluminum cylinder head cover can reduce the weight of the car, but also improve the heat dissipation effect of the engine.Cylinder head covers serve to seal off the cylinder head space from the outside of the engine. As a result of operation of the internal combustion engine, blow-by gases from the combustion process and oil droplets from the lubricant system of the engine are present inside the cylinder head.

A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber.
