PE-1200 Batch Pre-Expander — eps pre-expanders by ChinaEps, CE & ISO 9001 certified.
The PE-1200 is a batch-type EPS pre-expanding machine that expands raw polystyrene beads using steam to produce uniform low-density foam beads. It features a 1,200mm stainless steel barrel, 500-700 kg/h output capacity, and a high-precision electronic weighing system for consistent density control. Ideal for medium-scale EPS factories manufacturing insulation boards, appliance packaging, and construction panels.

Three production problems eliminated by this machine — with engineered, measurable solutions.
Mid-sized EPS factories outgrow PE-900 but PE-1400 wastes 30% steam at partial load
PE-1200 (500-700 kg/h, 22 kW) right-sizes for plants in the 800-1,500 t/year band — full barrel utilization, no steam waste.
Operators sometimes need to switch between block-molding and shape-molding bead grades on same shift
PE-1200 fast-recipe-change PLC keeps batch-to-batch switch time under 8 minutes (vs 20+ on manual controls) — enables flexible production planning.
Eight engineered subsystems that make this cutting line production-grade. Each component is sourced, built, and tested for industrial duty cycles.
Right-sized 1,200mm expansion chamber for 500-700 kg/h throughput. Double-layer insulation keeps steam waste low even on smaller batches.
304 stainless inner shell + 40mm mineral wool + steel outer shell. Working pressure 0.35 MPa. Pre-heat 7-10 minutes. Same insulation tech as PE-1400 scaled down.
Single-zone PLC steam regulation. Same control discipline as PE-1400 — smaller barrel doesn't mean looser tolerance.
Pneumatic control valve + digital pressure transducer. Setpoint 0.15-0.22 MPa. Steam recycling captures condensate — efficiency comparable to PE-1400.
Bottom-drive design eliminates the seal-leakage issues of top-drive agitators. Sized for 1,200mm barrel volume.
3-blade 316 stainless agitator, 5.5 kW SEW Eurodrive + 30:1 reducer. VFD speed control 15-45 RPM. Mechanical seal 10,000+ hours.
Same ±50g precision weighing as PE-1400. Fast-recipe-change PLC enables batch-to-batch switch in under 8 minutes — flexible production planning.
5 kg load-cell range, German HBK or Mettler-Toledo. Pneumatic gate valve. PLC stores 32 density recipes — covers all common density and bead-size combinations.
Same Siemens S7-1200 PLC as PE-1400. 10" Weintek HMI gives operators the full feature set of larger PE models on a mid-range machine.
S7-1200 PLC, 10.1" Weintek HMI. Multilingual UI. USB recipe export; optional Ethernet/IP for MES integration. Fault log 1,000 events.
Moves expanded beads to aging silo. Same Roots blower technology as PE-1400 scaled to 1,200mm output rate.
Ø125mm pneumatic conveyor duct (vs Ø150 on PE-1400). Anti-static design. Cyclone separator at silo inlet — 99% bead capture.
CE-compliant safety circuit — identical to PE-1400 standards on every machine in the family.
Pressure relief at 0.28 MPa. Two e-stop mushrooms. Steam pressure interlock. Thermal cutoff. CE per EN 60204-1 + EN ISO 13849-1 PLd.
Every advantage backed by measurable specs — no marketing claims without data.
Sweet spot for 800-1,500 t/year EPS factories.
Stored recipes (up to 32) cover all common density / bead-size combinations.
Double-layer insulated barrel — same as PE-1400 — keeps steam waste low even on smaller batches.
This machine is widely used across multiple industries and production scenarios.
A clear schedule keeps the line running. Built-in safety systems protect operators and product alike.
Inspect steam manifold. Clean weighing hopper. Check HMI fault log. Verify agitator start-up. Confirm pneumatic conveyor airflow.
Inspect agitator shaft seal. Lubricate gear reducer (NLGI-2, 50g). Drain steam condensate. Verify load cell calibration.
Clean barrel interior. Inspect agitator blades. Check pneumatic conveyor for bead accumulation. Backup PLC recipes to USB.
Recalibrate steam pressure transducer. Replace cyclone filter. Verify safety relief valve operation at 0.28 MPa.
Major overhaul: replace mechanical seal, recalibrate load cells, recertify safety circuit per EN 60204-1, update PLC firmware.
