Why Grey Iron Sand Casting Is Still Widely Used

Grey iron sand casting is a process that employs graphite-rich iron and sand molds to create sturdy pieces for the machinery, automotive, and heavy equipment industries. In fact, grey iron on its own, when used for the parts of the precision mechanical industry, shows a perfect combination of vibration damping, compressive strength, and excellent machinability — all highly sought features.

Sand casting, by definition, is a method for producing faster prototyping, complicated shapes, and cheap mass production without the need of using expensive/tooling. This is what makes it very valuable when manufacturing parts such as housings, valves, cylinder heads, and pump bodies.

Baoding Longway is utilizing this timeless but flexible method to provide custom cast parts with quality and technical precision that are stable, thus, able to fulfill both the standard and customized production requirements.

How It Compares to the Shell Mold Casting Process and Steel Sand Casting

While shell mold casting offers higher dimensional accuracy and smoother surfaces, it comes at a higher cost due to its reliance on resin-coated sand and heat-cured molds. In contrast, grey iron sand casting offers greater affordability and flexibility, especially for larger, thicker-walled parts where slight surface imperfections are acceptable and can be easily machined.

Similarly, 砂型鋳鋼 is favored for applications needing greater tensile strength, but it typically requires more complex heat treatments and machining. Grey iron, on the other hand, provides a practical balance of strength and castability, with lower energy consumption and reduced post-processing requirements.
