The advantages of sand casting exhaust manifolds are mainly reflected in cost-effectiveness, adaptability, material diversity, good air permeability, precision and good surface finish.

1. Cost-effectiveness: Sand casting is a relatively low-cost casting method suitable for large-scale production.
2. Strong adaptability: Sand casting can produce castings with complex shapes, including parts such as exhaust manifolds.
3. Material diversity: Sand casting is suitable for a variety of materials, including cast iron, alloy steel, etc.
4. Good air permeability: The air permeability in the sand casting technical indicators is crucial to improving the quality of castings.
5. Precision and surface finish: Using chemical bonding to form stronger molds and cores, this improves accuracy, enables thinner walls, and results in higher yields.
6. Quality control: Sand casting can effectively control the quality of castings.
7. Mature technology: Sand casting technology is mature and the process is stable.
