Gibson Centri Tech Limited – The Horizontal and Vertical Process

It is acknowledged that both Horizontal and Vertical Centrifugal Casting process can be used with ferrous and non- ferrous materials. The same machines can cast ferrous and non – ferrous, the only difference is some process features have to be tailored to suit the alloy, such as: 

• Spinning speeds
• Pouring rates
• Mould temperature
• Molten metal temperatures
• Mould coating
• Water Cooling

Horizontal Centrifugal Casting or Vertical Centrifugal Casting:

Horizontal Centrifugal Casting is best applied to castings of greater length than the diameter and which have cylindrical bore. This is why you will commonly find tubes between 300mm to 6000mm long. It is possible to create shaped casting horizontally using a shaped mould or sand inserts.

Vertical Centrifugal Casting on the other hand is commonly used for cylinder shapes where the diameter exceeds the length or height of the casting one exception to the are steel mill rolls where using a roller guide system, castings with a longer length to the diameter are manufactured this is to allow the manufacture of solid castings.

It can also be used for complex casting shapes such as Ball Valves and Propellers. 

Due to the Gravitational pull while pouring the material a parabolic effect takes place in the bore, this can be altered by changing the speed for casting.
