Behind every high-quality casting lies a precisely engineered pattern.

At Tianyu, our CNC lost foam carving machine is the silent force ensuring that even the most complex, large-scale castings achieve outstanding dimensional accuracy and consistency right from the pattern-making stage.

Why do we focus on this?
To provide our customers with custom-engineered solutions characterized by superior quality and optimized cost efficiency.

How do we accomplish this?
Ensuring Dimensional Consistency Across Castings
One casting, one pattern, produced in a single operation.
Eliminates dimensional deviations caused by wear and tear associated with conventional permanent molds.
Significantly improves dimensional conformity within the same production batch, facilitating seamless downstream assembly.

Why do we focus on this?
Especially advantageous for large structural components featuring intricate ribs, numerous cavities, or highly contoured surfaces.
Achieves carving precision to the millimeter level, ensuring maximum fidelity to CAD and 3D design specifications.

Reducing Capital Investment for Customers
Ideal for small production runs and intricate part shapes, eliminating the need for costly permanent tooling.
Patterns are delivered as single-use, ready-for-casting solutions, providing flexibility for prototyping or unique part configurations.

Agile Manufacturing and Rapid Turnaround
Lost foam casting can be seamlessly integrated with resin sand or traditional sand mold processes to accommodate diverse project requirements.
CNC pattern fabrication combined with rapid casting processes dramatically reduces lead times and enhances overall operational efficiency.

Moreover, the expendable foam materials we use are environmentally friendly and eliminate the challenges of storage, maintenance, and post-processing associated with conventional tooling, driving sustainable manufacturing practices further forward.

At Tianyu, we understand that behind every customized casting, customers care not about what processes we use, but whether our processes can give them peace of mind.

We continuously optimize workflows, combining three major casting technologies to select the best fit, not just the easiest. This is the service standard we uphold.
