Automotive Castings

  Over the 22 years,we,as a automotive castings manufacturer, have been manufacturing high quality automotive castings for a range of purposes in the automotive market. We have a great of experience manufacturing castings for the automotive industry. Our automotive castings are used the castings of choice for many leading vehicle manufacturers. Especially exporting to USA Market and Japan Market.

Why Casting?

  Casting is the most commonly used method of blank production.Casting methods can be produced for various types of automotive castings with complex shapes. Some parts that require wear resistance, pressure, vibration, and low cost (such as pistons, piston rings, cylinder liners, cylinder blocks, etc.).Some parts of automotive that are complex in shape and difficult to shape by other methods (such as cylinder heads, gearbox housings, and intake and exhaust manifolds) can only be produced by casting.

  With the development of casting technology, the application range of castings continues to expand.

  Forgings commonly used in the past have been replaced by castings. Such as crankshafts, connecting rods and gears.The main features of automotive castings are thin wall, complex shape, light weight, good reliability, high dimensional accuracy, and large annual production volume.Such as cylinder block, transmission case, steering gear housing, rear axle housing, brake drum, various brackets, etc.

The main Five Automotive Castings Materials and Characteristics

1.Automobile gray iron castings:

  A representative gray iron casting in a car is a cylinder block. Its development direction is thin wall and high strength. There are two main types of implementation. One is the low carbon process. It is Mainly to reduce the strength of cast iron by reducing the C and Si content of gray cast iron. The advantage is that it can be realized by changing the ingredients after the furnace. The reliability is high. Without or with little content of alloying elements. The cost is lower.

  The pretreatment and operation requirements are relatively loose. The disadvantages are also obvious: low carbon equivalent and poor casting performance. It is easy to cause shrinkage (loose) waste and increase casting stress. The processing properties of the castings, the uniformity of the section are poor. And the thermal conductivity of the casting is affected.

  The second is high carbon equivalent and alloying process. To maintain the C and Si content of gray cast iron at a higher level (wC>3.3%) and by adding alloying elements, such as chromium, copper, etc., to improve the strength of cast iron. At present, the development of multi-microalloying is increasing.

  The advantage is the alloying process is mature. The effect of the strength increasing is obvious. The casting performance is good. The tendency to form shrinkage (loose) waste products is small. The processing and thermal conductivity of the castings are good. The disadvantage is that the alloying elements are added more. Casting costs are not only high, but poor handling. So it can also affect the processability and leakage of castings. The pre-processing requirements are more stringent.

  As the engine power increases, the performance requirements for gray cast iron are further improved. Some cylinders of engines have been manufactured by HT300 or even HT350. FAW Foundry has used HT300 to produce 6DL and Deutz engine blocks. At the same time, it also reserves the production technology of HT350. By optimizing the smelting process, materials and alloying process. The high performance and high speed cutting of the cylinder material were successfully solved.

  2. Ductile iron castings

  Ductile iron is mainly used in automobiles. Sch as crankshafts, camshafts, mid-rear axle shells, various brackets, and shells.

  3. Vermicular iron castings

  Vermicular graphite iron has been widely used in automotive castings. Such as automobile exhaust pipes and high horsepower engine cylinder heads. Medium and high power engine cylinder heads are manufactured using vermicular graphite cast iron. On side. the weight of the cylinder head can be reduced by design. On the other side, the performance of the cylinder head improved can improve the power of the engine. The application of compacted graphite iron is mainly difficult to stabilize the control process.

  4. Austempered ductile iron (ADI)

  Austempered ductile iron has comprehensive mechanical properties with high strength, ductility and toughness. It is roughly divided into two categories, namely high strength type with strength of 1200-1600 N/mm2 and elongation of 900-1200 N/mm2. 10% high toughness type. Due to its excellent material properties, it has developed rapidly in developed countries of Europe and America. It has successfully applied ADI products in truck chassis, engine and car crankshafts. In the European market, ADI is increasingly used in cars, accounting for 32% of the entire ADI market. In the US market, heavy-duty and light truck ADI components account for 51% of the entire ADI market.

  5. Special cast iron

  With the improvement of engine performance, the heat resistance requirements of some castings, such as exhaust pipes ,are getting higher and higher. So silicon molybdenum ductile iron, medium silicon molybdenum iron and high nickel ductile iron appeared .

So if you have inquiry about the automotive castings,we can confirm the casting materials types and technology.

  Our Automotive Castings Services:

  Assembly analysis/casting integration:

  We work closely with our automotive clients, to identify new approaches and opportunities to save. For instance, we saved one customer 60% in production costs by figuring out that two castings and one piece could be cast as a single piece. With our help, the company could recoup its costs in under two years.

  Materials Anylasising:

  We’re also capable of analyzing chemical and metallographic characteristics to identify materials and post-production techniques utilized. After this is determined, we consult with our clients to create an effective course of action to move to production.

  3D Prototypes Design:

  3D Prototypes Design is a physical prototype. Prototypes help test the efficiency of a manufacturing process and give an accurate preview of how a part will look, feel and handle. Oftentimes, the prototypes we produce are fully functional.The customer can feel it directly.
