For developing a superior quality range of high alloy Centrifugal and Static Castings, we have incorporated advanced centrifugal technology in our production process. This centrifugal casting process is commonly known as ‘Liquid Forging’, which is used for producing cylindrical parts.
Characteristics of centrifugal casting process:
Centrifugal casting is the casting process specifically adapted to the production of cylindrical parts
Centrifugal casting pipes are made by pouring molten metal into a rotating mould
The metal is solidified in cylindrical shape with high centrifugal force
The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes
The inside diameter has more impurities and inclusions, which can be machined away
The process can also be adopted to produce various other products, using molds that can be permanent or expendable
The rotational speeds are lower than those used in centrifugal casting. This process is used for making wheels, nozzles, valve bodies etc. This process is known as Semi-Centrifugal Casting
Benefits of the centrifugal casting process:
Solidification happens at up to 120 times the gravitational acceleration, and consequently yields a highly compressed structure
The process is gravity and pressure independent
Mechanical properties substantially better as compared to static casting (can be compared with forged parts)
The directional solidification of the casting, yielding a very uniform structure, free from inclusions and blow holes
Not restricted to patterns (moulds, being permanent, mostly used from the extensive stock)
No restriction on tube thickness and weight (dependent on mould size)
No runners or risers are required for making of the product
