JNH-L Large-Size Up and Down Sand Molding Machine

1. Horizontal Sand Shooting: Compressed air is adopted for horizontal side sand shooting of molding sand, ensuring uniform filling and full compaction of the sand box, achieving pre-compaction effect simultaneously. It solidifies the foundation of sand mold forming and eliminates initial molding defects such as sand shortage and cavities.

2. Hydraulic Compaction: Precision hydraulic compaction ensures high and evenly distributed hardness of the sand mold cavity, effectively improving casting dimensional accuracy, optimizing casting surface roughness, and reducing subsequent processing procedures and costs.

3. One-Click Intelligent Operation: Equipped with touch screen control and graphic visual display, supporting fully automatic operation. The entire mold-making process can be completed with one click, which greatly lowers the technical threshold for operators, saves labor training costs and improves mold-making efficiency.

4. Linear Adjustment of Sand Shooting Height: The sand mold height can be linearly set arbitrarily within a limited range with precise and flexible adjustment. It adapts to the production requirements of castings with different height specifications and enhances the process compatibility of the equipment.

5. Servo Motor Controlled Hydraulic System: The hydraulic system is precisely controlled by a servo motor, featuring efficient, energy-saving and environmentally friendly operation. It not only reduces the enterprise's energy consumption costs and meets environmental protection requirements, but also decreases system wear and extends the service life of hydraulic components.
