Binder Jetting Technology

Tooling-Free Digital Casting: From CAD Directly to Sand Mold

Conventional foundry processes require weeks of pattern preparation — and every design revision means starting over. AJS1800 removes these constraints: no physical pattern or core box needed. Casting-ready sand molds emerge from a CAD file in hours.

⚡

Jump White — Intelligent Void Skipping

The software automatically skips areas with no binder data, eliminating unnecessary printhead passes and cutting total build time significantly.

🔄

Dual Jobbox for Continuous Production

One jobbox builds while the operator prepares the other. The system switches immediately when a job completes — downtime is minimized, daily throughput is maximized.

🎯

±0.3 mm Dimensional Accuracy

A 400 dpi printhead reproduces intricate internal channels, thin cores, and undercut geometries with consistent dimensional fidelity, reducing post-casting machining allowances.

♻️

Automatic Sand Reclamation

Unbound sand is automatically sieved and returned to the system after each build. Zero liquid waste discharge keeps the process clean and compliant.

Frequently Asked Questions

What You Wonder About

AJS1800 replaces the pattern and core box entirely. Sand molds and cores are produced directly from a CAD file — no wooden or metal tooling required. At the prototype stage, tooling cost drops to zero and design changes can be applied within hours. For medium-to-large complex-geometry castings, it reduces a multi-week pattern cycle to a few days.

Single-jobbox systems sit idle while the operator clears and resets the build box. With dual jobboxes, one box builds while the other is prepared. The machine switches immediately at job completion — downtime is minimal and daily output increases substantially.

The system is compatible with furan, phenolic, and inorganic binder systems. Sand options include silica, ceramic, and chromite. This flexibility supports a wide material range — from aluminium to ductile iron — on a single platform. Binder selection is determined by the cast metal and required mold strength.

High-temperature-resistant sand molds and cores can be produced for aluminium, gray iron, ductile iron, steel, and stainless steel alloys. The binder type is selected to match the casting metal and quality requirements, enabling a wide alloy range on a single machine.

KOCEL AJS1800 is engineered for industrial foundry conditions. Precision mechanical components and linear guides are protected by fully sealed dust- and heat-resistant seals. The integrated automatic sand reclamation system minimises operator intervention. With a standard daily inspection routine, the machine delivers long-term reliable operation.

Pattern and core box manufacturing costs are eliminated entirely. At the prototype stage and for low-volume custom parts, a multi-week tooling lead time shrinks to a few days. Design revisions require only a CAD update — a new mold can be in production the same day with no additional tooling expense.
