Die casting is a manufacturing technique used to produce metal parts. It’s cheap, fast, and widely applicable to different materials, especially for small-scale production. 

Automotive casting has been widely used in the automotive industry to produce engine components due to its high accuracy and efficiency. 

To meet the needs of various industries, there are many different types of die cast machines with different properties. 

Understanding all the pros and cons of each type will help you make an informed decision on which one is right for your application.

We will also look at the common methods in the automotive casting market.

At the end of it, youwill choose the best automotive casting companies that will meet your products requirements.

Why die casting is used for the automotive parts

Die casting is used to produce automotive parts which require high strength, dimensional accuracy, and surface finish.

 Since the method is inherently low-cost, it is used to make high volumes of similar parts and is not suitable for low-volume production applications.

Automotive die casting parts

The majority of automotive die cast parts are made out of zinc-based alloys because of the lower melting temperature of zinc alloys. Other widely used materials include aluminum and iron. 

For high-pressure applications, iron-based alloys are used. 

– Aluminum die-casting parts – Automotive parts aluminum die casting  are used for low-pressure components and include engine mounts, engine blocks, cylinder heads, and transmission housings. Due to the lower strength and ductility of aluminium, it is usually only used for low-pressure parts. 

– Iron die casting parts – Iron die casting parts are predominantly used for high-pressure applications such as engine blocks, crankshafts, connecting rods, and camshafts. Their higher strength and hardness are ideal for such components. 

– Zinc die casting parts – Automotive parts zinc die casting  are also widely used for both low-pressure and high-pressure applications. Since zinc has a lower melting point than both aluminium and iron, it is cheaper to produce. This makes it ideal for low-cost applications.

What is automotive investment casting?

Investment casting is typically used to produce parts that require intricate designs with small features.

 The process starts with an investment casting mould which is made from a wax or a cermaline ceramic material. 

The mould is filled with a liquid metal that has high flowability properties. Once the metal solidifies, a core is removed from the mould. This leaves a cavity where the cast part is to be placed.

 The core is then placed around the part, which is usually smaller than the cavity. The entire assembly is placed in a furnace where the part is heated above the melting temperature of the metal. 

The core is removed, and the part is now ready for use. Investment casting is commonly used to produce parts that are too complex for die casting, such as fuel injectors, camshafts, and crankshafts.

Overview of automotive die casting market

A die casting machine is an efficient and inexpensive tool for metal casting. It is used to make a wide range of industrial and consumer products, including car parts, electrical components, and various other goods.

 The global automotive die casting market is expected to grow at a high rate during the forecast period. This is due to the increasing demand for automotive parts in the automotive industry. 

The automotive industry is one of the largest industries in the world, and it is expected to grow in the future as well. 

The automotive industry uses die casting to produce engine components such as camshafts, crankshafts, and pistons. 

What is automotive sand casting

Sand casting is an old and traditional method of casting that has been used for centuries. 

It produces low-quality parts with rough edges and imperfections. The process involves pouring molten metal into a mould that is made from sand. The sand is mixed with water to create a slurry-like consistency.

 The sand mould is dried and then filled with molten metal. When the metal solidifies, it is broken away from the sand. 

This leaves a cavity in the mould where a part is to be placed. The sand is filled up again to create a new cavity where the next part is to be placed. 

Sand casting is typically used to produce low-quality parts with simple geometry. Examples include wheel hub housings and transmission cases.

Can aluminum be used in die casting?

Yes, aluminum can be used in die casting, although it is not commonly used in automotive investment casting. 

Die casting has a low melting point, and most aluminum alloys have a high melting temperature and are therefore unsuitable for die casting.

 A low-melting aluminum alloy is used for automotive die casting, such as AZ91, AZ92, and AZ63. 

There are also die cast aluminum alloys that are commonly used for other industries and not just automotive. They include 356, 356H, and 321.

In general, the automotive parts aluminum die casting market is large enough to meet the needs of the manufacturers.

Is Zinc used for the automotive die casting?

Zinc is commonly used for die casting in the automotive industry. It is a low-cost material that is used for low-pressure applications such as the engine block, cylinder head, and transmission case.

 – Zinc die casting parts have good ductility, strength, and corrosion resistance. They are widely used in automotive applications, as well as in other industries like electrical and marine.

Automotive engine casting

An engine block is the main component in an engine. The block is the central, structural component of an engine that houses the cylinders and other parts.

 The engine block can be divided into three sections – the cylinder block, the main block, and the connecting rod block.

Automotive die casting market has been dominate by companies that specialize on the engine parts.

And India is one country where you are likely to find plenty of such companies.

Most automotive certified die casting manufacturers in India avail these services to their clients.

Choosing automotive casting companies

When looking for an automotive casting manufacturers, you should always choose a reputable manufacturer that has a good track record.

 Reputable automotive casting suppliers will have a clean quality management system certification, such as ISO 9001. It will also use industry-standard practices when designing and manufacturing parts. This will ensure that all parts are designed to meet the required specifications. 

While checking out the certification, keep in mind that automotive casting China is fully regulated.

The most important thing when choosing automotive die casting suppliers is to make sure that it’s able to produce the type of parts you need. 

Conclusion

Die casting has been widely used in the automotive industry to produce engine components due to its high accuracy and efficiency. The choice of die casting for automotive parts is influenced by the following factors – durability, aerodynamics, weight, and cost.

 Automotive die casting parts include the engine block, cylinder head, and transmission case. Investment casting is typically used to produce parts that require intricate designs with small features.
