What is Die Casting Process?
 

The die casting process is a method that use high-pressure force the melted metal into the metal mold with complex shapes, and quickly solidifies under high pressure to obtain precision castings. It is mainly combined by the three major elements of die-casting machine, die-casting mold and alloy material.

 

The die casting process generally includes steps such as mold preparation, raw material preparation, heating and melting, mold closed, injection and cure cooling. This process method has the advantages of high production efficiency, simple process, high level of casting tolerance, good surface roughness, and large mechanical strength. It can save a lot of mechanical processing processes and equipment to save raw materials.

 

In the fields of automotive, electronics, machinery, aerospace and other fields, die casting technology has been widely used. For example, the cylinder head, cylinder body, crankshaft box and other key parts of the auto engine.And the shells of electronic products such as mobile phones, computers, cameras, etc., are often made of die-casting process.

 

 

 
Advantages of Die Casting
 

 

The die -casting process is to inject liquid metal into the mold, and the casting is formed by high pressure once.
So compared to other components made of welding, it has better strength and hardness. At the same time, the processing is flexible, which can create a smooth or graphic surface, making it easier for subsequent surface treatment. It can be processed with complicated parts of thin walls, and the comprehensive advantages make the die -casting process widely used in various industrial fields.

the process to make die casting parts
 

 

The process of making die -casting parts includes the following main steps:

 

Mold design: This step is the key to making die -casting workers. The designer needs to design mold design according to the structure characteristics of the product, wall thickness, mouth, and cooling system to ensure that the quality and shape of the final casting meet the requirements.
Raw material preparation: The raw material is the basis of the die -casting process. Commonly used raw materials include aluminum alloy, zinc alloy, magnesium alloy, etc. These raw materials need to be mixed according to a certain ratio and heated to melting state to prepare for subsequent injection molding.

Following: In this step, the raw materials are heated to a certain temperature, so that it is melted into liquid metal. The melting process requires strictly controlling temperature and time to ensure that the melted metal quality meets the process requirements.

Injection: The melted metal solution is injected into the mold through the injection machine. The injection process needs to accurately control the injection pressure and speed to ensure that the casting can fully fill the mold and achieve the required density.

Cooling: After the metal liquid is injected, it needs to be cooled quickly to solidify it. The cooling process is usually controlled by the cooling system inside the mold to ensure that the internal and external temperature of the casting is uniform, thereby avoiding thermal stress and deformation.

Post -treatment: The casting after cooling and curing needs to be removed from the mold, and then processed by the burrs, grinding, cleaning, and cleaning. These post -processing steps help improve the surface quality and accuracy of the casting and make it meet the requirements of the use.

FAQ of Customizing Die Casting Parts

01.What are the die casting parts?

Die casting parts are produced through the pressure casting process. This process uses the pressure casting machine (also called the die casting machine) installed with the casting mold to pour melted metal into the inlet (such as zinc alloy or aluminum alloy, etc.)，then through the pressure of the die casting machine, the liquid metal was die casted into the part which is restricted the shape and size by mold. After the manufacturing is completed, these parts are usually called die castings.

02.What the difference between hot chamber die-casting and cold chamber die-casting?

Cold chamber die -casting is a die -casting method at room temperature. It refers to adding cooled water to the melted metal or using other methods to quickly solidify and apply pressure when solidifying metal materials,it is suitable for high melting points, such as copper and iron.
Hot chamber die -casting is a processing method of suppressing and molding metal under heating conditions. It is suitable for metal materials with low melting points such as zinc and aluminum.

03.What products are suitable for die casting process？

Auto parts: engine cylinder head, cylinder body, crankshaft box

Electronic product shell: mobile phone, computer, camera shell

Kitchen appliance accessories

Household appliance accessories

Communication parts and boxes

04.What materials are suitable for creating die casting parts?

Aluminum alloy(A380,ADC12)

Zinc Alloy(zamak 3,zamak 5,zamak 7)

Magnesium alloy

Lead alloy

05.What disadvantage of die casting process?

The manufacturing costs of molds and die -casting machines are expensive, and they are not suitable for small batches. Noise and vibration may occur during the production process. It is difficult to cast high melting point alloys.There may be defects for castings. Such as pores and shrinkage, especially in castings with large wall thickness.Not suitable for all types of casting. It is difficult to produce large or overweight castings.

06.What surface treatment does Wochang offer for die casting parts?

Plating, powder coating, spray painting, sandblasting, anodizing, passivation and so on.

07.What is the mold material of die casting parts?

First,the most used for die -casting molds is H13.This material is cost -effective, so it is widely used.

Secondly, there is 3CR2W8V which is often used to make cold chamber die -casting molds. And SKD61,it is relatively expensive. It is often used for making molds with high quality requirements and large quantity orders.

08.What are the precautions when making die–casting molds?

Fully understand the needs and requirements of the product, such as size, shape, material, surface, etc. Select the mold material with high strength, good wear resistance, design a reasonable and fast cooling system, design the appropriate pouring position and shape,

Choose the right mold surface processing process, The maximum possibility improves the accuracy and quality of the mold, These are conducive to improving the service life of the mold and rapidly producing high-quality die-casting parts.

09.What does the surface temperature of die-casting molds affect the die-casting parts?

The control of the surface temperature of the die -casting mold is very important for high -quality die castings. The temperature of uneven or inappropriate die casting molds also causes the size of the castings to be unstable. During the production process, the casting is deformed, resulting in defects such as thermal pressure, sticky mold, surface depression, internal shrinkage, and hot bubbles. When the mold temperature difference is large, it has a different degree of impact on variables in the production cycle, such as filling time, cooling time, and spray time.

10.Why aluminum die casting mold is more expensive than zinc die casting mold?

Because aluminum has higher melting point, so it requires high quality steel mold, and During the manufacturing process of aluminum die -casting mold, high -precision technology and equipment are required.

11.What is the process of making die -casting molds
