Horizontal and Vertical Process – Centrifugal Casting

It is acknowledged that both Horizontal and Vertical Centrifugal Casting processes 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 temperatures
  • Molten metal temperatures
  • Mould Coating
  • Water Cooling

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 cylindrical shapes where the diameter exceeds the length or height of the casting one exception to this are steel mill rolls where using a roller guide system, casting 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 castings 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.

Alpha – Gyra and Alpha Uni- Gyra Machine Range of Centrifugal Casting Machines

Tags : 

This is the most popular series of Horizontal Machines manufactured by Gibson Centri Tech Limited. We can manufacture five basic sizes with an extensive selection of variations to suit individual specific requirements. Single or twin head machines versions are available.

The Alpha Uni – Gyra machine

This machine type is a high duty version of the Alpha – Gyra machines, having high capabilities with a range of optional production items including:

  • Programmable control unit.
  • Automatic mould coat spraying mechanical casting extraction, making it more suitable for mass production duties.
  • The twin head machines are best employed for medium to long production runs of cylinder liner castings of maximum 500mm internal diameter.


The Alpha – Gyra Machine

This machine is designed and manufactured to meet the requirements of one off, jobbing, medium to mass productions of cylinder castings for diesel and petrol engines, gear wheel blanks, high duty bushes for automotive and engineering duties and pump sleeves, in high duty nickel alloys.

What are the main features of the Alpha Machine Range?

  • Flange mounted mould
  • Easy to install & Operate
  • Low Maintenance
  • Reduced Noise
  • Flexible, Suitable for both
  • Used in the Production of cylinder liners, Valve Seals, Bushes and Warm Gear Blanks etc…..

Centrifugal Castings and Centrifugal Casting Machines

Did you know that centrifugal casting results in a superior casting with improved mechanical properties and purer structure when compared to static casting?

Centrifugal casting also:

Requires no in-gates or feeder heads

Comparable to forged castings in terms of mechanical properties and micro structure

Substantial savings on capital equipment

The centrifugal casting process is not limited to a specific type as most metals are castable and bi-metal castings are possible.

Contact a sales team to learn more on how Gibson Centri Tech Limited’s range of centrifugal casting machines can assist you and your foundry:
