Manufacturing Capabilities

To meet different requirements for cast iron components in terms of size, weight, and surface finish, we generally utilize shell mold casting and resin sand casting processes.

Shell mold casting is well suited for the production of high-volume components, typically weighing between 5 kg and 60 kg. Resin sand casting is generally used for larger and heavier parts. Parts with individual weights exceeding 60 kg are typically manufactured using this process.
