Die casting process flowchart

Highlights of Die Casting Technology
01 High dimensional accuracy and low surface roughness: Die cast parts perform well in both dimensions and surface roughness.
02 Superior strength and hardness: The castings not only have precise dimensions, but also have much higher strength and surface hardness than other processes.
03 Wide range of application fields: from lamp radiators to automotive parts, to furniture, bathroom hardware, etc., the application of die-casting technology is ubiquitous.
04 High productivity and automation: This process can produce efficiently and achieve automation, greatly improving production efficiency.
05 High metal utilization rate: Compared to other processes, die-casting technology is more efficient in metal utilization.
Classification of Die Casting Machines
The hot chamber die-casting machine has its pressure chamber immersed in a crucible for insulation melting, and the liquid metal directly contacts the injection parts. This design simplifies the production process, improves efficiency, and reduces metal consumption. However, the pressure chamber and injection punch that are immersed in liquid metal for a long time can be affected, shorten their service life, and may increase the iron content in the alloy.
The cold chamber die casting machine is different, as its injection chamber and injection punch are not immersed in the molten metal. But instead, a certain amount of molten metal is poured into the injection chamber through a spoon, and then the metal liquid is injected into the mold through the high-speed push of the injection piston. This design is suitable for die-casting of various metals such as aluminum alloy, pure aluminum, magnesium aluminum alloy, copper alloy, etc.
In addition, die-casting machines can be divided into horizontal and vertical types according to their structure. Next, we will delve into the process flow of die-casting products.
die-casting mold
Die casting molds are the core components in the die casting process and must be made of hot work mold steel to ensure their high temperature resistance and wear resistance. Commonly used steels include H2384084SKDDAC, FDAC, etc.
The structure of the mold is complex, including many components such as the mold frame, mold core, guide column, guide sleeve ejector pin, driver cylinder, splitter, sprue sleeve, slider, inclined guide column, etc. The precision machining and reasonable layout of these components are crucial for the quality and efficiency of die-casting products.
The processing of molds requires the use of various professional equipment, such as milling machines, CNC machining centers, wire cutting machines, spark machines, grinders, lathes, and welding repair equipment. The high-precision processing capability of these devices is the key to ensuring the quality of molds.
Application of Die Casting Technology
Die casting technology has been widely used in multiple industries due to its high production efficiency, complex casting shape, and high precision. For example, industries such as automobiles, tractors, electrical instruments, telecommunications equipment, aerospace, medical equipment, and light industry daily hardware all extensively use die-casting technology to produce various parts. Among them, important parts such as the engine cylinder block, cylinder head, and gearbox are refined through die-casting technology.

Conclusion
Die casting, as an efficient and reliable component customization technology, has excellent dimensional accuracy, high production efficiency, and excellent economic benefits, and has become an indispensable process for component customization. With the continuous pursuit of product quality, aesthetics, and durability in the manufacturing industry, the application areas of die-casting will continue to expand.
