Aluminium Alloy Gravity Die Casting, For Automobile Industry, Agriculture Industry

Gravity Die Casting :

Gravity Die Casting is a permanent mould casting process, where the molten metal is poured from a vessel or ladle into the mould. The mould cavity fills with no force other than gravity, filling can be controlled by tilting the die. Undercuts, and cavities can be incorporated into the component form with the use of sand cores. This process gives a better surface finish than sand casting as well as better mechanical properties, both due to rapid solidification. Compared to sand casting, this process requires less finishing and fettling and gravity die casting tends to produce a higher quality product. The Gravity die casting production method is generally less cost effective in the manufacture of tooling compared with sand casting.

Technical Specifications

• Weight : 0.300 to 15Kg

• Maximum Dimensions : 1000mtr

• Wall Thickness : ≥3mm. smaller is possible but depends on structure

• Draft Angle : 2º-3 º, depends on the height of Wall or Rib

• As far as possible, use uniform wall thicknesses to achieve a uniform solidification of material

Benefits

• Good dimensional accuracy

• Smoother cast surface finish than sand casting

• Reverse draft internal pockets and forms can be cast in using preformed sand core inserts

• Steel pins and inserts can be cast into the part

• Improved mechanical properties compared to sand casting
