Durable and Functional Components: The stainless steel dryer bed has a double-layer structure for enhanced heat insulation. The screw conveyer has a reversible operation mode for easy material backflow or cleaning. The sieving device has a replaceable screen for different bead size requirements.
Steam System Excellence: The accurate pressure reducer and PID control system of the accurancy batch polystyrene pre-expander machine can achieve a steam pressure accuracy of ±0.015 bar. The steam supply is regulated based on the material type and quantity, optimizing energy usage. The steam consumption is reduced by approximately 32% compared to standard expanders.
Pressure Control for Consistent Results: The pressure sensor in the polystyrene batch expander machine has a pressure range of 0.1 - 1.8 bar. The multi-steam exhausting system is designed to maintain a stable pressure within ±0.01 bar during the entire expansion cycle. This ensures that the beads have a uniform density and minimal size variation.
Temperature Control for Superior Expansion: The temperature sensor has a high sensitivity of ±0.03°C. The compressed air proportional valve can adjust the temperature in small increments, maintaining it precisely. This leads to a reduction in broken beads and an improvement in the mechanical properties of the expanded beads. The temperature control equipment also has a preheating function to reduce startup time.
Material Level Control Precision: The styrofoam batch expander machine's weighing scales have a zero-point calibration function for accurate measurement. The vibrated level sensor has a damping adjustment option to handle different material flow characteristics. The density tolerance is maintained within ±0.012 kg/m³.
Efficient Material Filling: The touch screen allows for the storage and recall of multiple filling recipes. The electronic weighing filling system has a rapid filling speed of up to 8 kg/min with a high accuracy of ±0.03 kg.
Reliable Electric Control: The PLC touch screen has a remote access option for monitoring and control. The branded electronic parts and valves have a warranty period of 2 years, providing peace of mind for the users.
The auto density-weighing system offers real-time density feedback and correction, enhancing the quality and consistency of the expanded beads.
The secondary expansion device for SPJ130 and SPJ160 enables the production of beads with unique density gradients, suitable for advanced EPS applications.
