Belt Cleaner Casting
Investment & Sand Casting Experts
Leesh Holdings delivers high-quality ferrous and non-ferrous castings for conveyor belt cleaner systems worldwide. From primary and secondary cleaner frames to tensioner assemblies and blade holders—we cast it all.
Your Partner in
Belt Cleaner Castings
With decades of combined experience in precision casting, Leesh Holdings has become a trusted supplier to mining industry manufacturers across North America, Europe, and Asia.
We understand that a belt cleaner is only as good as its cast components. That's why every casting we produce—whether investment cast or sand cast—is engineered for dimensional accuracy, wear resistance, and long service life in demanding bulk-material handling environments.
From prototype to high-volume production, we partner with your engineering team to deliver castings that perform.
Two Casting Processes,
One Quality Standard
Whether you need the precision of investment casting or the economy of sand casting, Leesh Holdings delivers to spec, on time, every time.
Investment Casting
Ideal for complex belt cleaner components that demand tight tolerances and smooth surface finishes.
- Tolerances as tight as ±0.005" (CT4–CT6)
- Complex internal geometries & thin walls
- Superior surface finish (Ra 3.2–6.3 µm)
- Low to medium volumes cost-effectively
- Minimal draft angles required
- Ideal for blade holders, brackets & small tension parts
Sand Casting
The go-to process for larger belt cleaner frames, heavy-duty bases, and high-volume production runs.
- Cope & drag, resin shell, and no-bake options
- Parts from 0.5 kg to 500+ kg
- Excellent for ductile iron & carbon steel
- Cost-effective tooling for high volumes
- Short lead times with pattern in stock
- Ideal for main frames, tension poles & mounting brackets

Casting vs. Fabrication
Why Casting Wins for Belt Cleaners
When it comes to belt cleaner components, the choice between a casting and a welded fabrication has a direct impact on cost, performance, and service life. Here's why leading OEMs choose casting.
Casting
- Significant cost savings — A single casting can replace 3–8 fabricated parts, eliminating welding, bolting, and alignment costs.
- Unlimited design freedom — Complex curves, ribs, bosses, and internal passages impossible to fabricate can be cast in one shot.
- Reduced part count — What would be a multi-piece weldment becomes a single casting. Fewer parts = fewer failure points.
- Dimensional consistency — Every casting is identical. No variation from welder to welder, no distortion from heat input.
- Superior material properties — No heat-affected zone (HAZ), no weld stress concentration. Uniform grain structure throughout.
- Less material waste — Near-net shape casting reduces machining scrap vs. cutting from plate or bar stock.
- Faster lead times for complex parts — A complex shape that takes weeks to fabricate can be cast in days once tooled.
Fabrication (Welded)
- Higher per-part cost — Multiple parts, multiple welds, more labor, more inspection.
- Limited geometry — Complicated shapes must be broken into many pieces and welded.
- More components to manage — Each bracket, gusset, and plate is a separate SKU.
- Weld variation — Distortion, porosity, and operator skill introduce inconsistency.
- Heat-affected zone (HAZ) — Weld zones are weaker, more brittle, and prone to fatigue cracking.
- High material waste — Cutting from plate produces significant scrap.
- Longer lead for complex parts — Fabrication is linear; casting can produce complex parts in a single pour.
