Model ID: DY170-1
The DY170-1 Cylinder Head is manufactured using the advanced Shell Mold Casting (Croning) process, a technique chosen for its ability to deliver superior precision compared to traditional green sand casting. By utilizing resin-coated sand that is heated to form a thin, rigid crust (or "shell") against the metal pattern, we achieve a mold with exceptional dimensional stability and surface smoothness. This results in a casting that captures fine details, such as deep, thin-walled cooling fins, with remarkably high fidelity and minimal surface roughness.
For OEM applications requiring complex internal geometries, shell molding is the ideal solution. The high permeability of the sand shell allows gases to escape efficiently during the pouring of molten aluminum, significantly reducing the risk of gas porosity defects. Furthermore, the rigidity of the cured mold allows for closer tolerance control on critical features like the intake and exhaust ports, reducing the machining allowance required in subsequent stages. This process provides a perfect balance, offering the geometric complexity of sand casting with a finish quality that approaches die casting, ensuring excellent airflow and heat dissipation performance.
