Product Features
JNH series -- Foundry machinery with up and down sand shooting way
The JNH Top and Bottom Sand Shooting Molding Machine is a servo-driven, high-pressure automatic molding solution designed to deliver superior mold quality for a wide range of casting requirements. Incorporating a top-and-bottom blow system, this automatic moulding machine for foundry achieves uniform sand compaction from both directions, effectively eliminating shadow effects and improving the surface finish of complex castings.
Available in single- or double-station configurations, the JNH series (foundry machining) features a rigid four-column structure for enhanced stability and an intuitive human-machine interface (HMI) for easy operation and process control. Key molding parameters such as extrusion pressure, mold height, and forming speed are fully adjustable to meet varying production needs.
By combining high-pressure hydraulic compaction, servo-controlled sand shooting, and automated mold ejection, the JNH series (moulding machine for foundry) offers a reliable, efficient, and operator-safe molding process ideal for high-volume, precision casting environments.
1. High-Speed Molding: The foundry machinery boasts a high-speed molding capability of up to 26 seconds per mold, without the need for additional core setting time, significantly increasing production efficiency.
2. Up and Down Sand Shooting Technology: The high pressure foundry machining equipped with vertical sand shooting technology, it is best suited for deep-pocket patterns to effectively eliminate shadowing, ensuring the quality of the castings.
3. Squeeze Pressure Balance Control: The squeeze pressure balance control ensures stable molding and prevents pattern distortion, enhancing the precision of the castings.
4. Mold Height Feedback Control: The mold height feedback control system reduces sand consumption and compensates for compaction variations, optimizing sand usage.
5. User-Friendly Operation: The high pressure moulding machine for foundry features a touch screen panel for easy operation, improving user-friendliness and reducing the difficulty of operation.

Product detail:
1. Advanced Bidirectional Sand Compaction Technology：
Our foundry machinery with up and down sand shooting way revolutionizes mold production by deploying simultaneous sand injection from both top and bottom directions. This innovative approach ensures uniform density distribution (95%+ compaction) and eliminates voids in complex patterns, making it ideal for precision foundry machining of intricate components like engine blocks or hydraulic valves. The bidirectional system guarantees flawless mold integrity, reducing casting defects by 50% compared to conventional methods. This technology is the core of our automatic moulding machine for foundry, enabling high-repeatability production for demanding industrial applications.
2. Fully Automated Turnkey Molding Solution：
Designed as a complete automatic moulding machine for foundry, this system integrates PLC-controlled automation for seamless operation. The machinery automates sand feeding, bidirectional shooting, high-pressure compaction (1,200-2,000 kN force), and mold ejection with ≤0.2mm dimensional tolerance. It serves as the centerpiece of a modern foundry line, compatible with foundry casting machine peripherals like automatic pouring systems and conveyor networks. With a output capacity of 200-450 molds/hour and reduced labor dependency, this equipment maximizes productivity while minimizing operational costs.
3. Superior Mold Quality for High-Value Castings：
This foundry mould machine excels in producing molds with exceptional surface finish and dimensional accuracy. The up and down sand shooting way achieves consistent mold hardness (90-96 HB) throughout the cavity, preventing sand inclusion, veining, and other common defects. Its capability to handle large-size molds (up to 1500x1200mm) makes it a robust moulding machine for foundry applications requiring heavy-duty castings. The system’s precision ensures compliance with ISO CT7-8 tolerance standards, reducing machining allowances and material waste by 30%.
