Hangzhou Epsole Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of eps continuous pre-expander machine in China. We warmly welcome you to buy high quality eps continuous pre-expander machine for sale here from our factory. Good service and reasonable price are available.
The EPS continuous pre-expander machine is a high-throughput equipment designed for mass production of expanded polystyrene (EPS) beads. Unlike batch-type machines that operate in discrete cycles, the continuous pre-expander maintains steady-state operation-raw EPS beads are continuously fed into the expansion chamber, expanded by steam, and continuously discharged for downstream molding or block production.
Key Selling Points
Capacity and Efficiency
High Throughput Continuous Production – Up to 1200 kg/h Capacity
The EPS continuous pre-expander is engineered for mass production, delivering a capacity range of 800–1500 kg/h depending on cylinder size and target density.
Density Range and Foaming Uniformity
Wide Density Range with Uniform Bead Expansion – From 12 kg/m³ to 160 kg/m³
The continuous pre-expander covers a density range of 12–160 kg/m³, providing versatility for various downstream applications
Continuous Foaming Process
Steady-State Steam Expansion Technology
Continuous Feeding
Steam Injection
Expansion
Continuous Discharge
Advanced Control Systems and Automation
PLC + HMI Automatic Control System - One Operator Manages Multiple Machines
Realizing the Value of Automation: In fully automatic mode, a single operator can simultaneously monitor 2–3 continuous pre-expanders, resulting in a significant reduction in labor costs.
Energy-Efficient Design and Operational Cost Optimization
Energy‑Efficient Operation – Reduced Steam and Power Consumption
Steam consumption for EPS pre-expansion typically ranges from 25–40 kg steam per 100 kg EPS (industry average: 50–60 kg).
