Liquid binder
Modified silicate binder technology for warm-box core making.
01 / INORGANIC BINDERS
Performance before
and after pouring.
Warm-box inorganic binder systems with a focus on humidity resistance and core removal in aluminum and iron casting.
THE LCIWB SYSTEM
A matched system.
With optional humidity reinforcement.
Powder additive
A matched powder selected for the binder grade and casting application.
Humidity-resistance enhancer
An optional third component to strengthen performance under humid storage conditions.
HUMIDITY RESISTANCE / LABORATORY EVIDENCE
Strength retained
after humid storage.
LCIWB two-component and three-component systems, tested under the same reported storage conditions.
At 1 hourAfter a further 2 hours at 25°C / 80% RH
| LCIWB system | At 1 hour | After humid storage | Strength retained |
|---|---|---|---|
| Two-component | 6.60 MPa | 5.73 MPa | ≈87% |
| Three-component | 6.68 MPa | 6.06 MPa | ≈91% |
Humid storage: a further 2 hours at 25°C / 80% RH. Retention compares post-storage strength with the one-hour result.
Flexural strength; 40–70 Dalin roasted sand. Equal bar scale: 0–7 MPa. Values rounded from LANCO laboratory data. Results apply to the tested systems and conditions.

WATER-DROP COMPARISON
See the difference
at the surface.
Water is absorbed by the competitor resin sample. On the LANCO sample, the droplet remains visible with no apparent surface change during the recording.
- Competitor resin
- Water absorption and a visible wet spot.
- LANCO inorganic binder
- A visible droplet remains on the surface.
Surface water response is shown here; the humidity-storage test above measures retained core strength.

Aluminum casting.
Two years of continuous production use.
2 yearsContinuous production use
6,000Cylinder heads tracked for validation
Full-processValidation inspection; no issues reported
From monitored validation to sustained production: following successful cylinder-head trials, the customer switched to LANCO and has used the system continuously for two years.
- 01 / VALIDATE
6,000 cylinder heads tracked
LANCO worked with the foundry on ongoing in-line monitoring and full-process inspection. No issues were reported during validation.
- 02 / ADOPT
Customer switches to LANCO
The successful validation supported the customer's transition to the LANCO binder system.
- 03 / CONTINUE
Two years in production
Continuous use followed the switch. The 6,000-piece figure refers to the validation batch, not total production.
Aluminum applications in China include cylinder heads and subframes for leading global automotive OEMs.
Production history updated October 2026.
ALUMINUM / SUBFRAME APPLICATION
Complex cores.
Structural castings.
IRON / CORE COLLAPSIBILITY & REMOVAL
Iron casting.
Core collapsibility proven in production.
LANCO has addressed the inorganic core collapsibility challenge in iron casting, with commercial-scale production across four applications.
Four applications. Different internal geometries.
Explore the engine-block sequence, valve-body section, exhaust passages and turbine-housing production footage.
See core removal and the resulting casting.
The application cases bring sand-core photographs, production footage and cast components together.
