Alum-A-Filter Non-Ferrous Metal Filtration Machine

General Description

The Alum-A-Filter provides continuous automatic metal filtration in many non-ferrous casting operations. The machine provides this filtration by indexing a continuous belt of mesh fabric between a molten metal receiving basin and a direct pouring basin. Molten metal is poured into the pouring basin, flows through the filtering screen, and into the receiving basin. Once out if the receiving basin, the metal flows directly into the shot tube of a die casting machine or pouring basin of a permanent mold machine. The process can even be customized for automatic green sand or no-bake molding operations with fixed sprue position pouring. This process effectively removes a high percentage of slag, dross, and other defect causing impurities.

The filtering cycle is completely automatic, triggered by a signal from an automatic ladler or the operator. A large supply of mesh filter fabric is continuously fed to the machine from a supply coil. A large filter coil can provide for hours of operation without human operator assistance. As the filtering cloth exits the machine, the amount of slag, dross, and other impurities can be seen in the dross "biscuit" captured by the fabric.

Options Options 

• Manual Swivel 
• Powered swivel for dual (or more) station operation 
• Larger pouring basins for increased ladle size 
• Larger filter surface areas available based on application

Applications

Die Casting - Metal filtration can be performed directly at the charge port of a shot tube on cold chamber die casting machines.

Permanent Mold Casting - The filter machine can be easily adapted to fit many permanent mold casting operations and provide automatic metal filtration for each pour.

Ingot and Pigging Operations - The machine can be positioned over the moving molds of a pigging line to filter metal going into each mold.

Sand Casting - The filter machine is easily adapted to mount over a pouring line of a automated green sand or no-bake molding machine. The only critical feature of this usage is that the sprue be consistently located.
