Product Description

The principle of the machines

This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold. 

It has the features of low investment, high efficiency, less labor, stable performance, agile production and extensive applicable scope, hence it is applicable to technical reformation in newly-built casting factory or old casting factory.  

 

The composition of lost foam sand processing line

 

 

Lost foam sand processing can be divided into: screening, magnetic separation and cooling, including dust removal equipment, elevator, sand hopper, electric control and so on.

  1. Screening equipments: vibrating conveyer screening (There are many kinds of types and models, adopting different types according to different spatial layout).
  2. Magnetic separation equipments: through magnetic separation, suspended magnetic separation.
  3. Cooling equipments: boiling bed, spiral elevator (as auxiliary equipment, not main cooling equipment), water cooling roller (adopting roller external water spray principle cooling), sand temperature regulator.

Seen from cooling effect, boiling bed and water cooling roller is better, comparing with each other: boiling bed is high consumption power, excessive noise, small occupied area, low water consumption, otherwise water cooling roller is low power, low noise, large occupied area, high water consumption.

Lost foam casting process (EPC process) is to let foamed plastic beads (good EPC material) become prepared casting shape according to foaming molding, bury in the dry sand after baking coating, vacuum pumping, pouring metal liquid, becoming casting or craft after cooling.

The advantage of the casting process

  • This casting process is advantageous for very complex castings that would regularly require cores.
  • It is also dimensionally accurate, maintains an excellent surface finish, requires no draft, and has no parting lines so no flash is formed.
  • As compared to investment casting, it is cheaper because it is a simpler process and the foam is cheaper than the wax.
  • Risers are not usually required due to the nature of the process; because the molten metal vaporizes the foam the first metal into the mold cools more quickly than the rest, which results in natural directional solidification.
  • Foam is easy to manipulate, carve and glue, due to its unique properties.
  • The flexibility of LFC often allows for consolidating the parts into one integral component; other forming processes would require the production of one or more parts to be assembled.
