• Aluminum Gravity Casting

  • Aluminum products are produced in volume by gravity casting. This method uses the force of gravity to fill a permanent mold with molten material without application of any external pressure. It will ensure that there will be less bubble vacancy formed during this process as compared to press casting method like die casting. Gravity casting has advantages of cost effective and good quality.
  • Aluminum couplings are made from alloy base of aluminum grade #A356 and #A380. After treatment like T6 heat treating that involves the use of heating to extreme temperatures for hardening purpose is carried out 100% on each coupling. Heat treating is generally more economical and more controllable.
  • To begin the process, a cast iron mold capable of producing tens of thousands of castings must be made in at least two sections to permit removal of castings.
  • In the casting cycle, the die caster clamps the two die halves tightly together. Molten metal is poured into the die cavity where it solidifies quickly. The die halves are drawn apart and the casting is ejected. Die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting.
