Product Features
JNH series -- clay sand molding machine with up and down sand shooting
1. Advanced Bidirectional Clay Sand Compaction Technology
Our clay sand molding machine with up and down sand shooting way revolutionizes traditional foundry processes with its innovative bidirectional compaction system. This vertical sand molding machine utilizes simultaneous top and bottom sand injection to achieve perfect density distribution throughout the mold cavity. The unique shooting method ensures complete pattern replication with zero voids, making it ideal for complex castings requiring exceptional dimensional accuracy. This technology represents a significant advancement over conventional single-direction shooting methods, delivering 35% higher mold hardness and 45% fewer casting defects while maintaining optimal moisture levels in clay sand mixtures.
2. Fully Automated Intelligent Molding System
This automatic sand molding machine provides complete automation for modern foundry operations. The integrated PLC system controls the entire molding process: automatic sand feeding, precision bidirectional shooting, high-pressure compaction, and mold ejection. As an auto sand molding machine, it features intelligent moisture control systems that continuously monitor and adjust clay sand conditions, ensuring consistent mold quality shot after shot. With a production capacity of 160-380 molds per hour and dimensional accuracy within ±0.2mm, this system reduces labor requirements by 60% while improving overall productivity by 55% compared to conventional molding methods.
3. High-Pressure Performance for Superior Mold Quality
Engineered as high pressure green sand molding machines, this equipment delivers exceptional mold quality for demanding clay sand applications. The combination of bidirectional sand shooting and high-pressure compaction (1,400-2,000 kN) achieves mold hardness of 88-94 HB, ensuring rigid molds that withstand handling and pouring operations. The machine's specialized design maintains perfect moisture distribution throughout the mold, preventing dry spots and ensuring consistent binder activation. This technology provides perfect pattern reproduction with excellent surface finish, reducing cleaning and machining time by 40% while minimizing clay consumption through efficient sand utilization.
4. Industrial-Grade Durability and Efficiency
Built for continuous clay sand operations, this automatic sand molding machine features heavy-duty construction with corrosion-resistant materials, hardened shooting nozzles, and industrial-grade hydraulics. The machine's robust design ensures reliable performance in high-moisture environments with minimal maintenance requirements. Specialized moisture-resistant components protect against clay accumulation and wear, while energy-efficient servo motors reduce power consumption by 30%. The optimized sand delivery system ensures 97% utilization of molding sand, and the enclosed design contains moisture and dust, creating a cleaner working environment.
5. Versatile Application Capability and Smart Integration
This advanced clay sand molding machine accommodates a wide range of foundry applications, from small precision components to large industrial castings. The bidirectional shooting technology handles complex geometries with deep pockets and undercuts that challenge conventional machines. As a high pressure green sand molding machines solution, it offers exceptional flexibility for various pattern sizes and configurations. Smart factory compatible with IoT connectivity, the machine provides real-time monitoring of sand moisture, temperature, and compression strength, enabling predictive maintenance and continuous process optimization for maximum efficiency and uptime.
