Binder Jetting 3D Sand Mold Printers
Produce casting-ready sand molds and cores directly from CAD data — no pattern or core box required. The 1800×1000×700 mm build volume and dual jobbox system deliver continuous binder jetting production from prototype to series.
Binder Jetting Technology
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.

Frequently Asked Questions
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.
