How to make aluminum foam

 
 
1. Aluminum smelting
 
The aluminium matrix is melted in the smelting furnace to obtain the aluminium-based melt and then transferred to the holding furnace for static insulation. The aluminium matrix is pure aluminium, aluminium-silicon alloy, aluminium-magnesium alloy, aluminium-manganese alloy, aluminium-copper alloy, aluminium-zinc alloy, aluminium-silicon-magnesium alloy, ALUMINIUM-SILICON-COPPER alloy, etc.
   
2. Viscosification and foaming of Aluminum melt.

Transfer the tackified aluminium-based melt to the foaming furnace, adjust the temperature of the foaming furnace, add the foaming agent after pre-heat treatment or surface coating treatment, and stir continuously to make the foaming agent distribute evenly all the time.
The foam aluminum matrix melt is poured into the thermal insulation crystallizer through the pouring nozzle at the bottom of the foaming furnace, and then solidified firstly under the primary cooling effect of the inner wall of the heat preservation crystallizer.
 
3. Foam aluminum slab cooling
Start the cooling fan and open the atomizing spray head, to cool foam aluminum by the air cooling and water cooling.  
4. Foam aluminum slab ready and then saw it according to customer requirements.

 Cut out the irregular edges vertically.

Cut into the thickness required by customers to make aluminum foam.
  5. Foam aluminum packing

6. Foam aluminum sheet, double-sided clad aluminum plate, or clad marble stone, forming foam aluminum sandwich panels.
