Low Pressure Castings Dealers in Rajkot

In this process, a metal mould/die is mounted on above a sealed furnace containing molten Aluminium metal. A riser tube connects the bottom of the die to the molten metal bath. The sealed furnace containing the molten metal is pressurised (typically 3-35 psi), and the metal is forced up into the mould/die slowly at a steady predeternmined rate. It is important to determine the rate of filling to avoid entrapment of air and turbulence giving homogenous defect free parts. The pressure is usually given to feed the defects like shrinkage normally associated with casting process. Once the casting has solidified (time duration 1-4 minutes typically), the pressure is released and the molten metal falls back into the bath, and the casting is ejected. Then the preparation for the next cycle begins. There is very high yields 90-95% in case of Low Pressure Die Casting leading because in effect the casting in a way acts as the gating system.
