SAND CASTING LINE
CORE SHOOTING MACHINE
A core shooter rapidly injects core sand into a core box, causing the compressed air inside to expand and compact the mold material. This process can accommodate both damp and dry materials in hot or cold core boxes. In a typical cold-box setup, prepared mold material is shot into a hydraulically clamped core box, preventing movement during filling and hardening. After shooting, the hardening device activates, allowing the core to set. Proper ventilation is crucial, with vents covering 3 to 5% of the box surface to facilitate even gas penetration and swift hardening.
Core shooter can utilize closed or open systems, effectively managing residual catalysts and ensuring a cleaner working environment. Hot box and warm box systems require external heat sources to enhance curing, offering low emissions and excellent shake-out properties.
Hot-Box Core Shooter
Hot-box core shooters are increasingly favored for their low toxic gas emissions and excellent shake-out properties during casting. These systems require external heat sources, such as electric heaters or gas combustion, to achieve optimal curing times. With core box temperatures between 250 and 350°C, they ensure high core hardness and improved surface quality, making them efficient for various applications.

Cold-Box Core Shooter
Cold-box core shooter rapidly injects core sand into a hydraulically clamped core box, causing compaction through the expansion of compressed air. This process accommodates both damp and dry materials, ensuring efficient hardening with well-ventilated designs that facilitate even gas penetration. The system is suitable for high-speed production of high-quality cores, optimizing foundry operations.
