Advantages:
Excellent dimensional accuracy (dependent on casting material, but typically 0.1 mm for the first 2.5 cm (0.005 in. for the first inch) and 0.02 mm for each additional centimeter (0.002 in. for each additional inch).
Smooth cast surfaces (1—2.5 μm (40—100 μin.) rms).
Thinner walls can be cast as compared to sand and permanent mold casting (approximately 0.75 mm (0.030 in.).
Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces).
Reduces or eliminates secondary machining operations.
Rapid production rates.
Casting tensile strength as high as 415 MPa (60 ksi).
Disadvantages:
Casting weight must be between 30 grams (1 oz) and 10 kg (20 lb).
Casting must be smaller than 600 mm (24 in.).
High initial cost.
Limited to high-fluidity metals.
A certain amount of porosity is common.
Thickest section should be less than 13 mm (0.5 in.).
A large production volume is needed to make this an economical alternative to other processes.
Advantages Of Die Casting
Because die casting is a pressurized molten metal, it can produce super smooth surface on the casting. When the molten metal is forced into the cavity, it fills completely to ensure a smooth surface. Another advantage of die casting is that it can minimize the demand of finishing process. Other types of casting process usually use machine to complete the casting, and the secondary processing operation is time-consuming and troublesome. The good news is that die casting reduces the need for this kind of operation. In many cases, castings can be shipped immediately after completion of the casting process.
Disadvantages Of Die Casting
On the one hand, compared with other casting processes, die castings are expensive, and the cost of purchase and maintenance of casting machine is very high. Even if relatively cheap zinc is used as casting raw material, the cost is also high. Some defects, such as flow marks, water marks, scratches, dents and so on, may also occur in the die casting.
Choose suitable Technics for your excellent idea according to Die casting Advantages and Disadvantages. Find manufacturing process of your parts with the most economic variation. I have summarized the Advantages and Disadvantages of die casting:
Advantages of die casting:
1. Good product quality
Casting dimensional accuracy is high, generally equivalent to 6~7, even up to 4;
Good surface finish, generally equivalent to 5~8;
High strength and hardness, generally higher than sand casting by 25~30%, but extended the rate is reduced by about 70%;
The size is stable and the interchangeability is good;
The thin-walled complex casting can be die-cast. For example, the current zinc alloy die castings have a minimum wall thickness of 0.3 mm; aluminum alloy castings up to 0.5 mm; the minimum cast hole diameter is 0.7 mm, and the minimum pitch is 0.75 mm.
2. High production efficiency
The machine has high productivity.The die-casting type has a long service life and a die-casting type. Die-casting alloys with a lifespan of several hundred thousand times or even millions of times; easy to mechanize and automate.
3. Excellent economic results
Due to the precise size of the die-casting parts, the surface is bright and clean. Generally, it is no longer mechanically processed and used directly, or the processing amount is small, so that the utilization rate of the metal is improved, and a large amount of processing equipment and man-hours are reduced; the price of the casting is easy; the combined die-casting can be used for other metal or non-metal materials. . Saves assembly time and saves metal.
Although die casting has many advantages, it also has some shortcomings that have yet to be resolved.
Disadvantages of die casting
1.Porosity on the die casting part and cannot be heat treated, As Two major features of die casting are High pressure and high-speed filling.
2.The up-front cost is pretty high. we need invest the mold before start mass production
3. Low die-cast life,High melting point alloys (such as copper, ferrous metals) ,As time went by ,Die Casting Defects out there on product has increased considerably.
4. It is not suitable for small batch production. The main reason is that the die casting type has high manufacturing cost, the die casting machine has high production efficiency, and the small batch production is uneconomical.

It is because of the advantages and unique advantages of the die casting parts that the die casting products are now more and more widely used. It plays an important role in many products such as laptop, mobile phone, camera, automobile and motorcycle. Among these products, die casting parts appear in front of consumers as fashionable, environment-friendly, humanized and innovative products, and consumers also highly approve of such products. With the development of die casting technology, die casting parts will certainly be more widely used.
Die casting is great for casting non-ferrous metals. If you can afford the initial tooling cost, it will prove to be very cost-effective in the long run. So, if you need a large-scale die casting solution, then die casting should be enough.
Investment casting should be preferred when you need to cast ferrous metals. There are no viable die casting methods that can cast ferrous metal successfully. So, when you have high-quality requirements and are not concerned about budget, investment casting can be chosen.
Die casting processes are used to make a wide range of products, from cylinder heads and engine blocks to furniture and bicycle frames. Die casting is a general casting process, which has both advantages and disadvantages for manufacturers. Many different metals and alloys are suitable for die casting. Zinc is a common choice for this casting process because of its high ductility and high strength, and it is relatively cheap, so it is very suitable for large-scale manufacturing applications. Other metals that can be used for die casting are aluminum, magnesium, copper, lead, tin and their corresponding alloys.

Die casting process is widely used in the manufacturing sector and automobile industries because of many advantages of the die casting process. Let us have a deep insight into the pros and cons of die casting.
Advantages of die casting :
Because of the use of movable cores, it is possible to obtain complex casting than that by permanent mould casting.
Production rate is very high. The typical rate could be 200 pieces per hour.
Die casting process is completely automated.
Very small thickness can be easily filled because the liquid metal is injected at high pressure.
Very good surface finish in order of 1 micron can be obtained.
The surface generated by the die casting process is directly electroplated without further processing.
Dimensional tolerance is very close in order n between +0.08 to -0.08 can be obtained.
The die has a long life.
Inserts can be readily cast in place.
This process is very economical for large scale production.
It will give better mechanical properties compared to sand casting.
Disadvantages of die casting :
Material limitations all material and alloy can not be cast.
The cost of the machine dies and other equipment is high.
Not economical for small quantity production.
Heavy casting can’t be cast by this process.
Limited to high-fluidity metals.
The air in the die cavity gets trapped inside the casting causes a problem of porosity.
Die casting is one of the most versatile and prolific metal casting processes, characterized by the use of a mold cavity to apply high pressure to the molten metal. The characteristics of die casting process contribute to design die casting parts to meet the requirements of the die casting process.
There are many sources for information on die casting design. These include text books, technical papers, literature, magazines, seminars and courses conducted by engineering societies, trade associations and industry. Often, the die caster selected to produce a component part is an excellent source for information.
To gain maximum advantage of the die casting process, it is always a good idea to draw upon the wide ranging experience of a custom die caster. New designs should be reviewed during the early stage of development. Significant savings may be realized during this interchange of ideas.
Die casting is one of the most versatile and prolific metal casting processes, characterized by the use of a mold cavity to apply high pressure to the molten metal. The characteristics of die casting process contribute to design die casting parts to meet the requirements of the die casting process. Now let’s take a look at the advantages and disadvantages of die casting, and the comparison of parts processed by other manufacturing methods.
ADVANTAGES OF DIE CASTING:
Easy for mass production – Since die casting is made from die casting mold, they can be obtained within specified tolerance and shapes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required. So it’s quiet easy to put on mass production.
Dimensional accuracy and stability – Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant.
Strength and weight – Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.
DISADVANTAGES OF DIE CASTING :
1) All metals and alloys can not be achieved.
2) The cost of machines, dies and other equipment used is high.
3) It’s not cheap to start with small quantity production.
4) Special precautions are necessary for evacuation of air from die cavity, otherwise cause porosity.
5) It’s impossible to get a die casting prototype when product development process.
As you know, die casting is a metal manufacturing process in which molten metal is forced under high pressure into mold tooling cavities. And easily to obtain the desired metal shape, nowadays, it is a widely used in automotive, lighting, industrial, and households.
It is because of the advantages and unique advantages of the above die casting parts that the die casting products are now more and more widely used. It plays an important role in many products such as laptop, mobile phone, camera, automobile and motorcycle. Among these products, die casting parts appear in front of consumers as fashionable, environment-friendly, humanized and innovative products, and consumers also highly approve of such products. With the development of die casting technology, die casting parts will certainly be more widely used.
I agree that using die casting is the way to go. At the company I work at, we recently switched over to using die casting and have seen incredible results. I believe that die casting is for sure the way to go.
The capital cost of foundry equipment and metal molds is high, which often limits the process of mass production. Die castings are relatively simple to manufacture and involve only four major steps, each with a lower incremental cost. It is especially suitable for large quantities of small and medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings have a good surface finish (by casting standard) and dimensional consistency.
