6 Common Casting Processes (Ⅱ)
In the previous article, we introduced sand casting, precision casting and metal mold casting. I believe everyone has a preliminary understanding of the characteristics of different casting processes. But the world of casting is far more than that. Today we continue to go deeper and talk about the three processes of die casting, centrifugal casting and low-pressure casting to see how they play their unique advantages in different scenarios and how our factory applies these technologies to the production of high-quality castings.
Die casting-fast speed, high precision, suitable for mass production:
If you need large-scale, high-precision, smooth-surfaced metal parts, then die casting must be your first choice. Die casting uses high pressure to inject molten metal into a metal mold (die casting is also called a die-casting mold), and the metal quickly cools and solidifies to form a casting with precise dimensions.
Centrifugal casting-high strength, no pores, designed for tubular parts:
If your product is a cylindrical, sleeve-shaped or tubular part, then centrifugal casting would be an ideal choice. Did you know that train wheels, hydraulic cylinders, some parts of pressure vessels, and even high-end engine cylinder liners are all products of centrifugal casting? Centrifugal casting can effectively remove pores and inclusions, making the casting structure denser, so it is particularly suitable for manufacturing parts that require high strength, high wear resistance and high toughness.
Low die casting - suitable for complex structures, taking into account strength and precision:
Some castings must have complex geometric shapes and ensure strength and durability. What should I do? At this time, Low die casting comes in handy. This method is to slowly push the molten metal into the mold from below at low pressure (usually 0.02~0.06MPa). Compared with traditional gravity casting, it can reduce pores, increase material density, and improve the mechanical properties of the casting. If your product needs to be both lightweight and have excellent mechanical properties, Low die casting will be your first choice.
