Cold-Cure Sand Casting for Large and Complex Parts
No-Bake Technology, also called chemically bonded sand casting, is a room-temperature moulding process where liquid binder and catalyst mixed with silica sand cure into a rigid mould without heat or ovens. The result: dimensional accuracy that rivals permanent-mould processes, geometric freedom beyond green sand, and virtually unlimited casting size. From precision parts to 50-tonne machine bases, No-Bake scales without compromise.
Unlike green-sand systems, the mould itself carries no residual moisture and no thermal distortion during setup, delivering cleaner surfaces, tighter tolerances, and fewer defects. Combined with continuous sand reclamation, the process is both high-quality and economically closed-loop: over 90% of moulding sand returns to the line after each pour.
The 7-Step No-Bake Process
A continuous, engineered flow from raw sand to finished casting, every stage designed and integrated by Axmann.
Sand Storage & Conditioning
Silica sand is metered from silos, dried, and temperature-controlled, the foundation for consistent, repeatable binder reaction.
Continuous Mixing
In-line single- or twin-shaft arm mixers inject liquid binder (furan, phenolic urethane, or alkaline phenolic) and catalyst directly into the sand stream.
Pattern & Mould Filling
Activated sand flows around the pattern and is compacted in the flask. Work starts before the chemistry ends, no waiting on ovens.
Ambient Curing
The binder hardens in minutes to hours at room temperature, no combustion, no heat input, no thermal distortion.
Pattern Removal & Closing
The cured mould half is stripped from the pattern; cores are set; cope and drag are closed and clamped for pouring.
Pouring & Cooling
Molten metal is delivered into the clamped mould at controlled temperature and flow; the casting solidifies and cools on a conveyor loop.
Shakeout & Sand Reclamation
Used sand is broken off the casting and mechanically and thermally reclaimed, returned to the storage silos to close the loop at 90%+ reuse.
What Axmann Provides
One supplier. One integrated line. One point of accountability, from concept through commissioning to decades of reliable operation.
No-Bake Technology in Detail
Advantages Over Green Sand & Permanent Mould
Unlimited Casting Size
From kilograms to tens of tonnes. The defining advantage over green sand, no upper ceiling on mould weight or geometry.
Superior Dimensional Accuracy
No moisture, no flask distortion, no thermal drift during cure, tolerances rival permanent-mould work without the tooling cost.
Binder Flexibility
Furan, phenolic urethane, or alkaline phenolic, chosen per casting alloy, emissions target, and cycle-time need.
Fewer Thermal Defects
Ambient cure eliminates mould-temperature variation, fewer gas defects, cleaner surfaces, higher first-pass yield.
Closed-Loop Sustainability
90%+ sand reclamation, lower new-sand input, lower disposal cost, lower carbon per tonne of good castings.
Scale Flexibility
Single-shift jobbing foundry or 24/7 series line, the same equipment family scales up without reinventing the process.
