Different types of die casting process mainly have hot chamber die casting, cold chamber die casting, vacuum die casting and others.
Die casting is an efficient and precise metal casting method, which is widely used to produce high-quality parts. According to different requirements and material properties, die casting can be divided into many types. Each of which has its own unique application scenarios and advantages.
1. Different types of die casting process: Hot Chamber Die Casting
Hot chamber die casting is one of the most common die casting processes, also known as gooseneck casting. In this process, the molten metal is in direct contact with the melting system and enters the mold cavity through a gooseneck tube. This process is suitable for low melting point metals such as zinc, magnesium, tin and lead. Its advantages include fast mold filling, high production efficiency and low equipment cost. But it is necessary to avoid using high melting point metals to prevent damage to the pump.
2. Different types of die casting process: Cold Chamber Die Casting
Cold chamber die casting is another major die casting process. It’s suitable for high melting point metals such as aluminum, copper and their alloys. In this process, molten metal is poured from an external melting container into a cold chamber. And then it inject into the mold cavity under high pressure. The advantage of this method is that it can handle metals with higher melting points while reducing the risk of metal oxidation. But the equipment cost is higher and the production speed is slower.
3. Different types of die casting process :Vacuum Die Casting
Vacuum die casting is a modified cold chamber die casting process. That reduces porosity by applying a vacuum before metal injection, thereby improving part quality and performance. This process is particularly suitable for applications that require high strength and low defect rates, such as in the aerospace field.
4. Low Pressure Die Casting
Low pressure die casting is a process that injects molten metal into a mold at a relatively low pressure. And it usually uses to produce large or thin-walled parts. The advantages of this process are that it can reduce defects caused by metal flow and reduce energy consumption.
5. Semi-Solid Die Casting
Semi-Solid Die Casting is a process that uses metal to inject into a semi-solid (paste) state, which can improve the mechanical properties and surface quality of parts. This process is particularly suitable for parts that require high strength and wear resistance.
6. Squeeze Casting
Squeeze casting is a process that injects metal into a mold by applying higher pressure, which can further increase the density and strength of the part. This process is often used for key components in the aerospace and automotive industries.
7. Gravity Die Casting
Gravity die casting is a process that uses gravity rather than high pressure to inject metal into a mold. It is suitable for producing small parts with simple shapes.
Different types of die casting processes have their own advantages and disadvantages, and choosing the right process depends on factors such as material properties, part geometry, size, and production requirements. For example, hot chamber die casting is suitable for small parts with low melting point metals, while cold chamber die casting is more suitable for large parts with high melting point metals.
