Integrated Component Design: The stainless steel dryer bed has a sloped surface for easy material discharge. The screw conveyer is made of high-strength alloy steel, ensuring durability and smooth operation. The sieving device is equipped with a vibration motor to prevent clogging.
Steam System Efficiency: The pressure reducer and PID control system of the accurancy batch polystyrene pre-expander machine work together to maintain a stable steam flow rate. The steam pressure can be adjusted in increments of 0.01 bar, allowing for fine-tuning of the expansion process. The steam consumption is optimized, with a reduction of up to 33% compared to older models.
Pressure Control Precision Engineering: The pressure sensor in the polystyrene batch expander machine has a digital display for easy monitoring. The multi-steam exhausting system is electronically controlled, enabling rapid pressure adjustments. The expansion chamber pressure is maintained within ±0.02 bar, ensuring consistent bead expansion and density.
Temperature Control for High-Quality Output: The temperature sensor has a response time of less than 0.3 seconds. The compressed air proportional valve can adjust the temperature based on real-time feedback, maintaining it within a narrow range. This results in a significant reduction in broken beads and a more uniform bead structure. The temperature control system also has a standby mode to conserve energy when the machine is idle.
Material Level Management: The styrofoam batch expander machine's weighing scales have a load cell accuracy of ±0.005 kg. The vibrated level sensor has a self-cleaning function, preventing material buildup. The combination ensures accurate material level control and a density tolerance of ±0.008 kg/m³.
Accurate Material Filling: The touch screen interface offers a password-protected access for setting filling parameters. The electronic weighing filling system has a double-check mechanism for added accuracy. The filling accuracy is within ±0.02 kg, and the filling volume can be adjusted from 1 - 10 liters.
Stable Electric Control: The PLC touch screen has a built-in diagnostic function for quick troubleshooting. The branded electronic parts and valves are tested for reliability before installation, ensuring uninterrupted machine operation.
The auto density-weighing system provides continuous density monitoring and automatic adjustment, improving the overall quality control process.
The secondary expansion device for SPJ130 and SPJ160 allows for further customization of bead properties, meeting the diverse needs of the EPS market.
