Production Process    
     
 
Today with the help of the modern technology "Lost Wax Casting" Process is being used to produce casting for almost all engineering fields especially for critical and complex items like aerospace components, valves for gas and oil etc. The modern lost wax process at GACL Involves the following steps...
 
       
  We prepare our product drawing with the help of CAD or manually and based on the drawing, the dies are developed from mild steel or Aluminum material.
 
     
  Molten wax is injected into the mould under pressure using wax injection presses and after specified time the mould opened to reveal a perfect copy of the original. Multiple wax patterns are then mounted around a stem of wax to create a "tree".  
     
  Plaster type slurry is repetitively (the coating parameters varies based on the type of the component) coated on these "trees", which sets solid on the wax patterns. Then these trees are heated to melt out the wax inside the cavities. After proper dewaxing and cooling process the shells are ready to receive molten metal to formulate the original casting.
 
     
  The required material is melted in induction furnace as per the relevant standards then the molten material poured in to the pre-heated shells. Online chemical analysis with Spectrometer is being carried out for each and every batch of molten metal.

After proper cooling, the shell is removed and castings are cut out from the trees then they pass through fettling, Heat Treatment, Blasting, Inspection, Packing and Dispatch.
 
 
     
  During all the above stages each wax pattern and shell are continuously monitored to ensure dimensional accuracy, finishing, similarity etc.
