Centrifugal casting
What is Centrifugal Casting?
This method is a horizontal and vertical casting method for manufacturing tube-type products according to the rotating axis of the mould by injecting a metal solution into a mold that rotates at a high speed of 300 to 3,000 RPM to obtain dense tissue by separating impurities by gravity. We develop vertical centrifugal casting construction (patent construction) for manufacturing ring-type products to respond to customers' needs.
※ When pouring molten metal, the mold is rotated at high speed and cast using its centrifugal force.
※ It is easy to remove metal inclusions due to fine tissue, no pores, and non-gravity differences.

Horizontal centrifugal casting
Advantages
- Easy manufacturing process
- Superior mechanical properties
- High productivity
- Appropriate to flange shaped and hard cutting metal products
- 15~20% lower cost comparing to horizontal type
- Possibility of making small inside diameter (min, 20mm)
- No internal defects
