We specialize in manufacturing Large Iron Castings, including Machine Tool Castings and Pump Housings. To meet diverse structural and precision requirements for large parts, we offer two advanced processes:
Lost Foam Casting : Uses expandable polystyrene (EPS) foam patterns embedded in dry sand with vibration compaction. During pouring, the foam vaporizes, leaving a casting with no parting lines or cores—ideal for complex shapes with intricate internal cavities, such as Machine Bed, Column, and Pump Volute. Dimensional accuracy reaches CT8-9 grade with superior surface finish compared to resin sand, eliminating core shift issues. This process is especially cost-effective for medium-to-large batch complex castings.
Resin Sand Casting : Uses furan or alkaline phenolic resin self-hardening sand, offering great flexibility for extremely large castings (up to dozens of tons). It is highly economical for single-piece or small-batch large structures like Base and Worktable, with accuracy of CT9-11 grade and adequate strength for heavy loads. Resin sand castings have high internal density, making them suitable for pressure-retaining parts such as Pump Body.
Our engineering team will recommend the optimal process based on your complexity, batch size, and precision requirements—we can even run trial castings using both processes for comparison.
