Comprehensive Componentry: The foam beads making machine incorporates a stainless steel dryer bed for efficient drying, a screw conveyer for smooth material transfer, a filling system, and a sieving device to ensure the quality of the expanded beads.

Steam System Excellence: The advanced accurate pressure reducer and PID control system work in tandem to maintain steam at an extremely stable and accurate level. This not only ensures consistent material expansion but also minimizes steam wastage. The pressure can be adjusted within a range of 0.1 - 1.5 bar, providing precise control over the expansion process.

Pressure Control Precision: Equipped with a highly sensitive pressure sensor and a multi-steam exhausting system, the polystyrene batch expander machine keeps the expansion chamber pressure steady. This results in a significant reduction in steam consumption, typically by 20 - 30%. The pressure sensor has a measurement accuracy of ±0.05 bar.

Temperature Control Mastery: The temperature sensor and compressed air proportional valve collaborate to maintain an accurate expansion temperature. This is especially beneficial for high-density expansion, reducing the occurrence of broken beads by up to 40%. The temperature can be set between 80 - 120°C, and the temperature control equipment's energy-saving capabilities are remarkable, conserving approximately 25% of heat energy.

Material Level Control Accuracy: The styrofoam batch expander machine utilizes accurate weighing scales and a vibrated level sensor. This combination ensures a minimal density tolerance of ±0.02 kg/m³, guaranteeing the consistency of the expanded beads.

Efficient Material Filling System: Through the touch screen interface, operators can easily set the filling weight. The electronic weighing filling mechanism then enables the batch expander machine to fill materials accurately and automatically, with a filling accuracy of ±0.1 kg.

Reliable Electric Control: The PLC touch screen, along with electronic parts and valves sourced from renowned brands, orchestrates the entire working procedure of the polystyrene batch expander machine. This automation not only enhances productivity but also ensures stable and reliable operation.

The auto density-weighing system of the accurancy batch polystyrene pre-expander machine is available as an optional feature, providing even more precise control over the density of the expanded beads.

A secondary expansion device for SPJ130 and SPJ160 is also an optional addition, allowing for further customization of the expansion process to meet specific production requirements.
