Functions

1. Decontaminate the melting metal liquid
2. Simplified gating system
3. Improve the metallurgical structure of the castings
4. Reduce imparitied of the castings
5. Improve casting quality rate
6. Reduce casting internal re-oxidation defects
7. Reduce the surface defects after machining of the castings

Advantages

1.Increased Fluidity
Removal of inclusions makes the metal more fluid, resulting in easier mold fill, better cast structure, and better thin section castability.

2.Reduced Mold and Die Wear
Removal of inclusions and other nonmetallic debris from the melt reduces die soldering and mold-metal interaction, which degrades the mold surface and service life.

3.Longer Tool Life
Oxide as well as intermetallic inclusions create “hard spots” that damage tools in machining and finishing operations. Filtration reduces tool wear and increases productivity.

4.Fewer Rejects
Inclusions nucleate porosity, create hot tears during solidification,cause surface defects that mar appearance, and often reduce mechanical properties. In many cases, filtration cuts rejects from such causes to virtually zero. Improvements in yield to near 100% and reduced reject rates to at or near 0% are common.
