Robust and Functional Machine Parts: The stainless steel dryer bed has a temperature uniformity of ±5°C. The screw conveyer has a low-noise operation, ensuring a quiet working environment. The sieving device has a high throughput capacity, handling large volumes of material efficiently.
Steam System Efficiency and Precision: The accurate pressure reducer and PID control system of the accurancy batch polystyrene pre-expander machine can adjust steam pressure with a resolution of 0.005 bar. The steam supply is optimized based on the expansion ratio, reducing waste. The steam consumption is reduced by 34% compared to average expanders.
Pressure Control for Stable Expansion: The pressure sensor in the polystyrene batch expander machine has a long-term stability of ±0.003 bar. The multi-steam exhausting system is designed to maintain a constant pressure within ±0.008 bar during the expansion process. This stability results in beads with a uniform density and excellent physical properties.
Temperature Control for Quality Assurance: The temperature sensor has a temperature drift of less than ±0.02°C over time. The compressed air proportional valve can maintain a constant temperature within ±0.03°C, reducing broken beads and improving product quality. The temperature control equipment also has a power-saving mode during standby.
Material Level Control Precision: The styrofoam batch expander machine's weighing scales have a high sampling rate for accurate weight measurement. The vibrated level sensor has a wide detection range, ensuring proper material level management. The density tolerance is within ±0.009 kg/m³.
Efficient Material Filling: The touch screen allows for the programming of multiple filling sequences. The electronic weighing filling system has a fast response time, ensuring accurate filling within ±0.015 kg. The filling volume can be adjusted from 2 - 8 liters.
Reliable Electric Control: The PLC touch screen has a user-defined alarm system for various machine parameters. The branded electronic parts and valves are designed for easy maintenance, reducing downtime.
The auto density-weighing system offers continuous density monitoring and control, enhancing the overall quality of the expanded beads.
The secondary expansion device for SPJ130 and SPJ160 provides an opportunity to produce beads with enhanced insulation properties, meeting the demands of energy-efficient EPS applications.
