Mould Handling/Dressing Devices TRIZ Cases

See how a spiral-rod mechanism converts manual pressing into rotation for dewatering, cutting,

Magnetic separation and dry pneumatic flotation remove impurities while preserving shell-mold sand particle size for reuse.

Controls foundry sand charge and supply by reserve thresholds so required aging time is secured before delivery to sand-related devices.

Shaft detectors provide real-time position feedback to correct voltage-induced errors, ensuring precise molding reproduction without manual intervention.

Mechanical abrasion removes binders from sand grains, enabling effective thermal cleaning without chemical additives.

An ultrasonic surface treatment apparatus generates air bubbles to crack and remove the binder, reducing recycling costs.

Multi-stage crushing and classification separate binder shells from used foundry sand, reducing disposal costs and landfill requirements.

A secondary cooling apparatus uses a comb tooth-shaped device to hold cast thin pieces during gradual and rapid cooling stages.

A supply amount calculation apparatus corrects water feed in a decompression kneader using tank level and weight data.

Refrigerating pipes cool sand at the duct outlet to form a thermal seal, preventing blockages during shutdown and eliminating mechanical valve complexity.

Opposite drum rotation suppresses non-magnetic entrainment, resolving the productivity versus precision trade-off.

A multilevel gas feed apparatus breaks molten silicon droplets into uniform shot particles using inert gas flows.

Ultrasonic cavitation extracts chemicals from used molding sand faster than acid washing while eliminating environmental pollution.

Heating the slurry to 80-100°C accelerates binder dissolution, resolving energy consumption trade-offs while ensuring complete separation.
