In metallurgical cooling equipment, there’s no single answer — only the right process for each part.

When producing critical components such as cooling staves, chequer supports, and wear plates, we follow one principle: Let the casting process serve the design — not the other way around.

This is why we've integrated Sand Casting, Lost Foam Casting, and Coated Sand Casting into our production — each optimized for a different challenge.

Sand Casting: Best for Robust Components

For large, durable parts like chequer supports or base structures, Sand Casting is our go-to method. Here’s why:

• Low cost, fast turnaround
  Ideal for large quantities with quick production times.

• Flexible mold setup for multi-variant production
  Easily adaptable for different designs and variants.

• Mature process — perfect for raw blanks or pre-machining stock
  A tried-and-true method for simpler components before further processing.

Sand Casting offers excellent value for large and robust components that don’t require highly .

Lost Foam Casting: Precision for Complex Structures

When dealing with large, intricate components like integrated cooling walls or asymmetric hollow sections, Lost Foam Casting excels. Here’s why it’s an ideal choice:

• No parting lines or cores — enables single-piece hollow casting
  Seamless designs without the need for additional assembly.

• Excellent for complex cooling channel designs
  Ideal for designs with intricate, embedded features.

• Low pattern cost — flexible for multi-variant, mid-volume production
  Cost-effective and adaptable for small to medium production runs.

• Simplifies fabrication — reduces welds and assembly errors
  By casting parts in a single piece, we avoid costly fabrication steps.

Lost Foam Casting takes us from “castable geometry” to optimal design freedom, enabling advanced geometries and complex cooling features.

Coated Sand Casting: Precision for Medium-Sized Parts

For medium-sized, precision parts like furnace grates, connecting plates, and frame elements, Coated Sand Casting is our solution of choice:

• High dimensional accuracy — essential for sealing and fitment.

• Smooth surface finish — reduces post-machining requirements.

• Durable patterns — cost-effective for repeated batches.

• Good resistance to hot cracking — suitable for thin-walled and ribbed parts.

Coated Sand Casting is perfect for high-repeat, geometry-sensitive components, ensuring precision and durability for critical industrial parts.

The Right Process for Every Design

At Tianyu, we don’t simply choose a casting process — we select the best-fit process based on the part’s design, thermal behavior, batch size, and downstream requirements. Whether we’re producing large, complex, or precision parts, we ensure the best solution for every challenge.
