1. Iron casting gearbox housing is made of cast iron, which can withstand the high-intensity and high-vibration operation of tractors in farmland. 2. Tractor transmission gearbox housing uses sand casting method, which has high production efficiency and is suitable for the large-scale production needs of tractor gearbox housing. 3. The surface of tractor transmission gearbox housing is machined, and the surface of the housing is smooth.

1. Add alloy elements such as Mo and Cr to cast iron housing materials to enhance anti-oxidation and anti-corrosion capabilities. 2. Regardless of size, shape or special requirements, we can customize cast iron housing according to your needs. 3. Cast iron housing is cast with resin sand, and the sand mold has good air permeability, which can reduce pore defects and improve strength.
