Product Features
JNH series -- Sand injection molding machine with up and down sand shooting
The JNH Top and Bottom Auto sand injection 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 Sand injection molding machine and support machineryachieves 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 (Big size Sand injection molding machine) 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 (sand injection blow molding machine) offers a reliable, efficient, and operator-safe molding process ideal for high-volume, precision casting environments.
1. Top and Bottom Sand Shooting System – Dual-directional sand blowing of the vertical sand injection molding machine ensures uniform filling and compactness throughout the mold, enhancing mold surface hardness and casting precision.
2. High-Pressure Hydraulic Compaction – Adjustable hydraulic pressure enables fine-tuned control over mold density, ensuring consistent quality across castings of varying complexity.
3. Servo-Controlled Operation – Advanced servo systems provide precise control over shooting and compaction processes, optimizing performance and energy efficiency.
4. Adjustable Mold Height and Squeeze Speed – Mold height and forming speed can be modified to accommodate a variety of casting specifications while minimizing sand usage.
5. Four-Column Rigid Frame – The machine’s robust structure ensures high precision and stability during high-speed operation.
6. User-Friendly HMI Interface – Centralized touchscreen controls allow for parameter setting, real-time monitoring, troubleshooting, and maintenance support.
7. Automated Blowout and Mold Ejection System – Streamlined hydraulic systems automate mold release and transition to the pouring line, improving production flow.
8. Lubricated Guide Columns – Integrated lubrication reduces wear and maintains alignment accuracy, extending machine lifespan.
9. Operator Safety Features – The control panel is positioned outside the machine’s operating zone and equipped with safety light guards to protect personnel during operation.
