Low Pressure Die Casting:

Fair production rates, may be mechanised, e.g. 30 castings/hr.

• Thin wall thicknesses possible, e.g. 2-3mm.
• Good dimensional control achievable.
• Good surface finish possible.
• High yields 90-98%, as runners and risers excluded.
• Reduced fettling and trimming.
• Pore-free castings obtainable.
• Use where directional solidification of castings is advantageous.
• Riser tube draws metal from below the dross layer, avoiding inclusion entrapment.
• Sand cores may be used.  Complex casting shapes are possible.
• Can fully heat treat castings.
