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

Sand Casting :

Sand Casting is one of the Widely used Techniques, which is used both manually as mechanically (such as a semi-auto molding line and a auto molding line), depending on the quantities required. It is mostly used for aluminium Alloy Casting. Tooling is mostly made of metal or composite materials, which guarantees a long life. However, tooling can also be made out of wood, in order to reduce the cost price. These are often selected in case of small and/or one-of series.

The disadvantage of this is that the surface roughness is less smooth than with an aluminium tooling. The production process is quite simple, although cores can be used to achieve complex shapes. However, consideration must be taken to the draft angles and the manner in which tooling divisions are built up. This technique is suitable for small as well as large series, ranging from around 200 grams to several tons.

Technical Specifications

• Weight : 0.100 to 20Kg

• Maximum Dimensions : 1000mtr

• Wall Thickness : ≥5mm. smaller is possible but depends on structure

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

Benefits

• High production adaptability

• Small quantities are possible

• Large components can be made
