Gravity die casting
Gravity die casting was one of the very earliest processes to be invented for metal and light alloy die casting. In this process which can be fully automated, the molten metal is poured directly from a ladle into a semi-permanent or permanent die.
The goal is to fill the die with minimum turbulence through one or more channels to reduce oxidation and foaming. This minimizes porosity and inclusions, giving optimum metal characteristics in the final casting.
Gravity die casting equipment can have a vertical or horizontal mold opening, or tilting technology with 0/90 ° or 0/120 ° tilting provides an alternative. With tilting die-casting, the metal flow at the die inlet is controlled by the tilting angle and speed of the die.
Advantages
- Produce parts with dense, high quality castings with excellent mechanical attributes like strength and stiffness
- suitability for high-volume, automated production
- minimum investment required for small and medium volume production
- produces parts with excellent mechanical properties that are also suitable for heat treatment
- produce parts with complex shapes.
Application
Gravity die casting technology is ideal for diverse complex aluminum casting production of automotive parts such as: turbos, brake calipers, knuckles, engine cylinder heads, engine blocks and pistons. It suits many other industries too, from lighting components to kitchen tools.
