The sand casting processes comparison : Green Sand Casting against Resin Sand Casting and Sodium Silicate Sand Casting and Dry Mould Casting compare.
Most parts are made by green sand casting and resin sand casting processes, especially cast iron parts. Some steel parts are manufactured by sand casting process.
Sand casting process | Production Method | Order Quantity | Quality Price | Weight Range (reference) |
Green Sand Casting is better for cast iron, carbon steel and light alloy aluminum copper alloy | making mold by hands | smaller | pass | no requirement |
making mold by lift-machine | more | normal | under 20kg | |
making mold by simple machine | middle | superior | under 30kg | |
making mold by Auto molding line | larger | excellence | under 100kg | |
Resin Sand Casting is better for cast iron,normal for steel and stainless steel | baking | smaller and middle | superior | over 5kg |
no baking | smaller and middle | superior | over 10kg | |
no baking by production-line | larger | superior | over 30kg | |
Sodium silicate bonded sand casting better for steel | baking | smaller and middle | normal | over 5kg |
no baking | smaller and middle | pass | over 10kg | |
dry mould casting better for iron and light alloy | baking | smaller and middle | pass | over 50kg |
