Industrial Fully Automatic Horizontal Molding Line for Sand Molding

The Fully Automatic Horizontal Molding Line is a continuous sand molding system based on horizontal parting and high-pressure squeeze or air-impact compaction, engineered for high-volume, high-speed production of gray iron, ductile iron, and steel castings—such as engine blocks, brake drums, pump/valve housings, and pipe fittings. Fully integrating automatic sand filling, high-pressure compaction, fast pattern withdrawal, mold closing, pouring, cooling, shakeout, and sand reclamation, it enables near "lights-out" operation with a capacity of 400–800 molds per hour, representing the benchmark of modern smart foundries.

Molding: Upper and lower flasks are filled simultaneously and compacted via high-pressure squeeze (≥1.2 MPa) or air-impact + multi-cylinder pressing to form molds with hardness HB 90–95 and high dimensional accuracy.
Coating & Core Setting (optional): Robots apply coatings and insert cores automatically.
Closing: Robotic arms align and close upper/lower flasks with ±0.1 mm precision.
Automatic Pouring: Servo-controlled pouring furnace delivers precise molten metal weight.
Controlled Cooling: Chain or roller conveyor provides stress-relief cooling.
Shakeout & Reclamation: Vibratory shakeout separates castings; spent sand is crushed, magnetically separated, screened, cooled, and recycled at ≥95% rate.

Ultra-High Efficiency, Economies of Scale
Annual output: 1–3 million molds. Replaces 50–100 workers. Reduces total casting cost by over 30%.

Consistent, High-Quality Castings
Uniform mold hardness (CV ≤3%) enables dimensional accuracy to CT7–CT9 and surface roughness Ra ≤25 μm, with scrap rate <1.5%.

Flexible Production & Quick Changeover
Quick-change pattern system (<15 min). PLC stores ≥500 recipes—ideal for mixed-model production.

Green & Smart Manufacturing
≥95% sand reuse. Integrated dust/VOC abatement. 20% lower energy use. Full data logging for MES integration and traceability.

High Reliability & Easy Maintenance
Core components from global brands . MTBF ≥5000 hours. Remote diagnostics & predictive maintenance supported.

Automotive: Engine blocks, cylinder heads, crankcases, differential housings
Construction Machinery: Hydraulic manifolds, gear cases, track rollers
Energy: Wind turbine hubs, nuclear valves, pump casings
Municipal & Piping: Ductile iron fittings, manhole covers, fire hydrants
