Which Tractor Parts Need to be Cast?
Casting process is suitable for parts with uneven wall thickness, or with complex shape or internal structure that cannot be fabricated.
For tractors, there are lots of parts like above that need to be cast, including:
|

Which Kind of Casting is Better for Casting Tractor Parts?
Simple parts (counterweight / flywheel): Sand casting or lost foam casting
Large castings (gearbox housing / rear axle casing / reducer casing): sand casting / lost foam casting
Complex structure parts (wheel hub / valve block): lost foam casting for cast iron; lost foam casting for low price cast steel; investment casting for durable cast steel
Aluminum: permanent mold casting (gravity casting) or die casting
High strength parts: sand casting or lost foam casting for low price; investment casting for better surface and high precision.
As a comprehensive foundry, Shata Machinery has all above casting processes for selection.
Our casting experts will help customers choose the right casting method for the parts they require.
Shata Machinery: Empower Your One Stop Purchasing of Casting Tractor Parts
Introduction to Shata's casting processes:
- Sand Casting: Mold (wooden mold or metal mold) + sand molding(resin or water glass sand)+ sand core for internal cavities
Advantages of sand casting are lower cost, easy to produce for large parts and complex parts, it is suitable for tractor parts like rear axle housing, transmission case, engine block, flywheel housing.
- Lost Foam Casting (Evaporative Pattern Casting / EPC): Foam pattern with fireproof materials, buried in dry sand, foam vaporizes and is replaced by metal during pouring.
Compared with sand casting, lost foam casting can create foam patterns with high efficiency, is ideal for medium and large orders like tractor wheel hub, steering knuckle, etc.
- Shell Molding: Sand pattern created by metal mold, pouring metal into sand pattern to get the castings
Shell molding has higher precision and higher efficiency, can produce both iron and steel castings with high efficiency.
Shell molding price is a little higher than lost foam casting, while its surface and precision is better than lost foam casting
- Investment Casting (Lost wax casting): Metal mold (aluminum or steel) -> wax pattern -> wax assembly -> silica sol shell -> dewax -> roasting -> pouring -> shell removing -> gate cutting & grinding -> heat treatment (if needed) -> shot blasting
Investment casting has the highest precision (CT4-CT8), best surface finish, while it also has the highest price.
Investment casting is suitable for high-end steel castings, such as precision gear, connector.
- Permanent Mold Casting: Pouring molten aluminum into metal mold to get castings
Permanent mold casting is suitable for aluminum parts, not suitable for cast iron.
It has good accuracy and smooth surface, is the first choice for aluminum tractor parts.
