Automatic EPS Shape Molding Machine

Product Overview：

The GB-SPZ1400-1750PT represents state-of-the-art technology in fully automatic Expandable Polystyrene (EPS) foam molding equipment. Designed to meet the core demands of modern EPS packaging and molding plants for high efficiency, low energy consumption, user-friendly operation, and maintenance safety, this model integrates a precise PLC control system, an intuitive touchscreen HMI, a robust and stable hydraulic drive system, and optimized thermal processes (steam heating, water cooling, and vacuum cooling). It achieves fully automated, precise control throughout 

the entire production cycle, from material feeding to finished product ejection. Its outstanding performance and user-centric design make it the ideal choice for boosting production efficiency and reducing operational costs.

Core Advantages：

1. Robust & Stable Hydraulic Drive System:

• High-Power Hydraulic Motor + Reinforced Machine Body: Utilizes a high-power hydraulic power unit (standard 11kW oil pump, superior to the common 7.5kW) coupled with a high-flow pump, delivering abundant power.

• Ultra-High Speed & Stable Operation: The optimized hydraulic system design, combined with a unique double-hinged frame structure, ensures exceptionally smooth and vibration-free operation even at high mold closing/opening speeds of up to 260mm/s. Compared to conventional machines, this significantly saves 3-4 seconds per cycle, dramatically increasing production efficiency.

• Innovative Product Removal & Structural Design: Features an automatic conveyor belt to swiftly remove molded products from the work area. This design allows for reduced machine leg height, working in tandem with the stable double-hinged frame to guarantee overall rigidity and stability during high-speed operation.

2. Accurate, Stable & Efficient Steam Heating System:

• High-Flow Steam Supply: Equipped with large-diameter steam piping (main pressure reducing valve: Japan brand DN100), with DN65-DN80 steam connections for each mold side, ensuring rapid and ample steam supply.

• Intelligent & Precise Temperature Control: Employs SMC (USA) PID Proportional Control Valves and Balance Valves at critical points for accurate and stable steam pressure regulation. This not only guarantees uniform and repeatable heating – essential for producing high-quality, consistent EPS products – but also effectively reduces steam energy consumption and shortens heating cycle time

3. High-Efficiency Vacuum Cooling System:

• Dual-Stage Cooling Design: The machine features a high-efficiency vacuum tank with an integrated top-mounted water spray system (water cooling). An additional stainless steel (S.S.) heat exchanger is installed inside the tank, creating a unique "dual-stage cooling" mechanism.

• Significantly Enhanced Cooling Efficiency: This design rapidly condenses large volumes of hot vapor, significantly improving vacuum suction efficiency and consequently drastically reducing cooling time, further boosting the overall production cycle.

4. Intelligent Control System & Operator/Maintenance Focus:

• Fully Digitalized Control: Based on an advanced PLC controller and a large touchscreen HMI, all process parameters (pressure, time, temperature, etc.) can be intuitively set and monitored via the screen.

• Precise Process Execution: Key actions (such as filling, heating, and demolding) are precisely controlled via SMC digital PID valves, completely replacing traditional mechanical manual valves, ensuring process consistency and repeatability.

• Convenient Maintenance & Safety: Human-centric design is evident in maintenance accessibility: the control cabinet features a recessed installation (positioned at ground level), and spacious maintenance platforms surround the machine and provide access to the top, greatly facilitating daily inspections and servicing while enhancing operator safety.

Application Areas：

The GB-SPZ1400-1750PT Full-Automatic Foam Forming Machine is the ideal equipment for:

• EPS Packaging Products (protective packaging for appliances, electronics, fragile goods, food, etc.)

•  EPS Building Insulation Materials (blocks, decorative moldings, etc.)

• EPS Industrial Component Liners & Cushioning

• Other fields requiring high-quality, high-efficiency EPS molded products.
