The significance of in-depth product development lies in its ability to optimize manufacturing processes based on product structure, delivering superior performance without increasing costs across different production methods.
Previously, we produced pipe fittings, accessories, and channel gratings using lost foam casting and manual operations. Through continuous innovation and expertise accumulation by our technical team, we have upgraded to coated sand casting. This transition has greatly improved product quality stability.
Coated sand castings
-High dimensional accuracy and excellent surface finish, effectively reducing or eliminating post‑machining.achieve dimensional accuracy ranging from CT7 to CT8, with surface roughness Ra 6.3–12.5 μm. By adopting coated sand casting, we have realized zero subsequent machining while ensuring high dimensional precision.
-Stable casting quality with fewer defects such as porosity, shrinkage and deformation.
-Good collapsability of coated sand, making shakeout and cleaning easier and more efficient.
-High production efficiency and strong reproducibility, suitable for batch and mass production.
-Wide adaptability to complex structures of castings, ensuring clear and complete contours.
-Low labor intensity, friendly working environment, and improved overall production efficiency.
-Compatible with various cast materials including cast iron, ductile iron and alloy steel.
