Operation Method of EPS foam shape molding machine production line

Core Features

· Automated Control: Modern machines are fully automated with PLC controllers and touch screens, which manage the entire cycle from clamping to ejection .
· Efficient Heating: They utilize advanced steam penetration technology to ensure even expansion and strong fusion of the beads .
· Speedy Cooling: Integrated vacuum systems accelerate cooling, which reduces cycle times and lowers moisture content in the final product .
· Hydraulic Clamping: High-pressure hydraulic systems ensure the mold is locked tightly during injection, preventing leaks and defects .
· Key Technical Specs: Standard machines typically operate with steam at 0.6–0.8 Mpa and compressed air at the same pressure, consuming 1.5–3 m³ of air per cycle depending on size .

Operation Method (The Cycle)

The machine follows a fully automatic, repeatable cycle:

· Clamping & Filling: The mold closes and locks. EPS beads are then vacuum-injected into the cavity .
· Heating (Fusion): Steam penetrates the mold, heating the beads to expand and fuse together into a solid shape .
· Cooling: Water mist or vacuum is applied to stabilize the shape and harden the product .
· Ejection: The mold opens, and ejector pins push the finished part out .
