SPJ50/90/130/160 Batch Pre-expander-A (Accuracy)

Product Description

The SPJ50/90/130/160 Batch Pre-expander-A is an advanced EPS foaming machine designed to enhance production efficiency and improve foam quality. Utilizing cutting-edge technology, this machine offers precise bead expansion, faster production, and reliable performance with low fault rates. It ensures the most accurate expansion of EPS beads, resulting in lighter, more uniform beads and a smoother operation.

Main Features

1. Complete Pre-Expander System

   • The EPS pre-expander machine includes a stainless steel dryer bed, screw conveyor, filling system, and sieving devices, offering a complete solution for EPS bead expansion.

2. Advanced Steam System

   • The machine is equipped with a precise pressure reducer and PID control system to maintain stable and accurate steam. This system ensures minimal material variation and keeps the pressure inside the expansion chamber stable, with an error margin of only ±2%.

3. Precise Pressure Control

   • A pressure sensor is integrated with the multi-steam exhausting system to stabilize expansion chamber pressure and reduce steam consumption. This helps achieve consistent bead size and quality.

4. Accurate Temperature Control

   • Temperature sensors and a compressed air proportional valve ensure precise control of expansion temperature, particularly suitable for high-density EPS beads. The system’s hot air drying accelerates the drying process, speeds up the aging process, and reduces the production time, which minimizes bead breakage.

5. Material Level Control

   • The machine features accurate weighing scales and a vibrated level sensor control to minimize errors caused by vibrations during the operation. This ensures accurate material filling and consistent foam density, improving product quality.

6. Automated Material Filling System

   • The machine uses an electronic weighing system, allowing operators to set the filling weight via the touchscreen. The system then automatically fills with precision, reducing human error and improving operational efficiency.

7. Intelligent Electric Control

   • The PLC control system and touchscreen interface allow for easy and intuitive operation. The use of high-quality electronic parts and valves from reputed brands ensures smooth and stable automation throughout the production process.

Optional Features

• Auto Density-Weighing System: For even more precise control over material density, this system can be added to further optimize foam production.

• Secondary Expansion Device: Available for the SPJ130 and SPJ160 models, offering enhanced expansion capabilities for more specialized applications.

Key Benefits

• Precision and Accuracy: The combination of the PID control system, pressure sensors, and temperature control ensures highly accurate foam production, reducing bead defects and improving product consistency.

• Energy Efficiency: By optimizing steam pressure, temperature, and material usage, the machine minimizes energy consumption and operational costs.

• Fast Production: The hot air drying system and precise control mechanisms reduce the time required for bead aging and drying, speeding up production cycles.

• Reliability: Built with high-quality components and advanced control systems, this machine delivers stable performance with minimal downtime.
