How Does Binder Jetting Work?

An end-to-end digital production technology that frees the foundry industry from physical constraints. Sand molds and cores are produced directly from digital CAD (STL) files — no physical pattern required.

1️⃣
Sand Spreading (Recoating)
A thin, homogeneous layer of casting sand is spread over the build platform at micron-level precision.
2️⃣
Binder Jetting
High-resolution industrial inkjet printheads selectively jet liquid binder (resin) according to the cross-section data from the digital CAD file. This cycle repeats layer by layer.
3️⃣
Depowdering & Cast-Ready Mold
After printing, unbound loose sand is automatically sieved and recovered. The result: a high-strength sand mold ready for direct liquid metal casting.

Beyond Traditional Foundry

Leave behind weeks of pattern manufacturing, high tooling costs, and revision bottlenecks.

📐
Unlimited Geometric Freedom
Forget draft angles and core assembly constraints. Complex internal channels, undercuts, and thin walls are printed in a single piece — no assembly, no flash.
⚡
Bidirectional Ultra-High Speed
Simultaneous sand spreading and binder jetting in both forward and reverse passes. Up to 1500 L/h throughput meets industrial series production demands.
🤖
Smart Void Skipping (Jump White)
Intelligent control software automatically detects and skips over empty regions with no print data, dramatically reducing total build time.

What You Wonder About

The system spreads a thin, homogeneous layer of casting sand onto the build platform (recoater). High-resolution industrial inkjet printheads then selectively jet liquid binder (resin) according to the cross-section data from the digital CAD file, bonding the sand. This cycle repeats layer by layer. After printing, unbound loose sand is sieved and recovered automatically, yielding a high-strength sand mold ready for direct liquid metal casting.

AJS1800A: Ideal for medium-to-large scale parts such as pump casings, volutes, and small engine blocks, as well as rapid prototyping requirements. AJS2500 & AJS4000: Mega systems designed for the continuous, tooling-free series production of massive wind turbine housings, large ship propellers, heavy equipment chassis, and high-volume automotive/defense components. Multiple different part geometries can be printed in the same job box simultaneously.

No. The KOCEL AJS series is specifically designed and built for heavy-duty foundry conditions. The precision mechanical rails, ball screws, motors, and printhead architecture are equipped with high-performance seals and protective enclosures that completely prevent dust ingress. Integrated automatic lubrication and constant-temperature fluid control systems ensure stable 24/7 operation even in harsh production environments.

The inorganic binder option eliminates organic VOC emissions and odors from the foundry entirely — a critical advantage for worker health and compliance with strict environmental regulations. Additionally, unused free sand is recovered at rates up to 90% through integrated sieving systems, reducing consumable costs significantly.
