China Auto EPS Pre-expander Machine with Reduced Steam Consumption

Product Description

The SPJ50/90/130/160 Batch EPS Pre-expander Machine-A (Accuracy) utilizes advanced technology to enhance the production of EPS foam. Designed for efficient foaming, this machine significantly improves both production efficiency and the quality of EPS beads. It ensures precise, lightweight, and fast expansion with reliable operation and low failure rates, while also optimizing steam consumption.

Main Features

1. Complete Pre-expansion Equipment
   The batch EPS pre-expander machine includes a stainless steel dryer bed, screw conveyor, filling system, sieving device, and more, ensuring a fully integrated solution for EPS foam production.

2. Efficient Steam System
   The machine is equipped with an accurate pressure reducer and PID control system, including a proportional steam valve, ensuring stable and precise steam control. The pressure inside the machine remains consistent, with a bead foaming error within ±2%.

3. Pressure Control System
   The pressure sensor and multi-steam exhausting system ensure stable pressure in the expansion chamber, while reducing steam consumption, enhancing energy efficiency without compromising on quality.

4. Precise Temperature Control
   A temperature sensor and compressed air proportional valve maintain accurate expansion temperatures, suitable for high-density foaming. The hot air drying system accelerates the drying process, speeds up aging, and shortens the production cycle, resulting in less broken beads and improved product quality.

5. Material Level Control
   The accurate weighing system and vibrating level sensor ensure precise material filling and consistent density, minimizing variations due to vibrations during operation and guaranteeing a reliable expansion process.

6. Automated Material Filling System
   Set the filling weight via the touchscreen interface, allowing the machine to automatically and accurately fill materials based on the pre-set weight parameters, improving efficiency and reducing manual input.

7. Stable Electric Control
   The PLC touchscreen, along with components and valves from reputed brands, ensures the entire machine operates automatically and reliably, minimizing downtime and enhancing long-term stability.
