Casting Of Brake Drum from Aluminum Scraps Using the Traditional Loss Wax Technology

Abstract

The brake drum  for  automobile was produced using the traditional loss was casting technique. Wax pattern was constructed incorporating the necessary allowances. Sand moulding technique utilizing locally materials was used for preparing the mould. Aluminium scraps was used as the casting materials. The aluminium craps was melted using the crucible furnace and finally pouring of the molten metal into the sand mould to obtain the piston. After fretting and cleaning, the cast piston was found to be good. The casting yield was found to be 66.67% which indicate that sound casting was obtained.
