To continue the discussion about contemporary or modern casting, we will discuss tilt casting this time.
We previously discussed centrifugal casting; do you remember what that is? Yes, centrifugal casting is pouring molten metal into a rotating mold. The mold is rotated vertically or horizontally until the molten metal freezes in the mold.
What is tilt casting ?
Tilt casting is a type of casting in which molten metal is inserted into the mold cavity using gravity. When molten metal is poured into the mold, the mold is tilted slowly from a horizontal to a vertical position at an adjustable speed and then left to stand until it freezes. Metal molds are used in the oblique casting method (die casting).
Parameters for Tilt Casting
The angle of inclination and pouring speed are two factors that influence this castin g method.
Angle of tilt
The tilt angle influences the increase and decrease of the material’s mechanical properties.
Pouring speed
The proper pouring speed can reduce the cooling rate and increase the metal grain size structure. Pouring too quickly, on the other hand, can cause turbulence and air trapping in the mold, resulting in gas hole defects in the casting.
Engineers must conduct trials (trial errors) to determine the correct and effective parameter sizes in order to produce a quality casting product.
Advantages of the Tilt Casting Method
This method of casting has several advantages, including:
- Reduces the risk of gas hole defects.
- Low turbulence.
- Can control the filling of molten metal.
- Directional freezing thereby reducing the risk of porosity defects.
- Casting results are better than conventional casting.
So, that’s the discussion about the tilt casting method, starting from the definition, parameters, and advantages. If you have any questions or need more information, please leave them in the comments section or contact our team directly.
