Product Component

Machine Structure
High-strength frame: The further enhanced back frame and moving frame, the whole polystyrene machine adopts the body and foot, and makes the frame and machine feet integrated, This greatly increases the frames strength and sturdiness of the polystyrene machine.

The polystyrene machine are treated with zinc spraying after the manufacturing works which improves load life of the expandable polystyrene packing machine.

The expandable polystyrene packing machine with vacuum adopts opposite directions type tie bar for easy maintenance and wear resistance. The self-lubricating copper tube solves original tie bar bushing's problem and improves the lubrication effectiveness of the polystyrene machine.

The preventing plate and back mould plate of the polystyrene machine with vacuum are all stainless steel, which reduces the wear and rust of the mold precision.

Hydraulic Pressure System
Hydraulic cylinders for the machine frame movement have safety locking of the mold during the steaming process and avoids the leakage of steam of the expandable polystyrene packing machine.

Special hydraulic pressure design: the ejecting cylinder and de-mold cylinder can be running simultaneously, which senses the de-mold gas blowing and product ejection synchronization effectively, reducing running time and improves de-mold capability of the expandable polystyrene moulding machine.

Steam System
The expandable polystyrene moulding machine controls the steam pressure by balance valve and pressure sensor instead of electronic connector pressure gauge. The mold pressure of the expandable polystyrene moulding machine can be set by touch screen.

Piping System
For the complete inlet and outlet of water, air and steam, the big pipeline and vales which are very close to the mold, reducing the excess energy consumption, while improving running speed of the expandable polystyrene moulding machine.

Impact on Construction Projects

EPS Shape Molding Machines play a vital role in the construction process by efficiently and effectively shaping expanded polystyrene (EPS) foam into desired forms. This innovative technology has revolutionized construction projects, offering numerous benefits that enhance both the quality and efficiency of the construction process.
One of the significant impacts of EPS Shape Molding Machines is the ability to create lightweight and durable building materials. EPS foam, produced by these machines, possesses exceptional insulation properties, making it an ideal choice for construction projects. The lightweight nature of EPS foam reduces the overall weight of the structure, which not only saves construction costs but also minimizes the strain on the foundation. This makes EPS foam a perfect material for constructing energy-efficient buildings that ensure optimal thermal comfort while reducing energy consumption.
EPS Shape Molding Machines enable the production of intricate designs and shapes that were previously challenging to achieve. The versatility of these machines allows architects and designers to explore their creativity by incorporating unique and aesthetically pleasing elements into construction projects. From decorative moldings to complex architectural features, EPS foam can be easily molded into any desired shape, providing endless possibilities for innovative designs.
EPS foam produced by Shape Molding Machines offers excellent resistance to moisture, rot, and insects. This durability factor extends the lifespan of construction projects, ensuring their long-term sustainability. Moreover, EPS foam is resistant to molds and fungi, making it a safe and healthy choice for buildings.
The utilization of EPS Shape Molding Machines also contributes to the reduction of construction waste. By optimizing the foam production process, these machines minimize material wastage, leading to a more sustainable construction industry. The ability to produce accurate and precise shapes also reduces the need for additional finishing materials, further minimizing waste generation.

Operational Steps

Preheating and Boot Heating
Before operation, the EPS moulding machine requires preheating to ensure the mold is at the optimal temperature. This step involves heating the boot, which is crucial for the mold’s heating action. Proper preheating helps in achieving uniform heat distribution, essential for quality EPS product formation.

Clamping and Mold Adjustment
Clamping involves the reasonable adjustment of the opening and closing die stroke. This adjustment is beneficial for improving product demolding and feeding efficiency. Key components like the push rod and die seam, along with the slow opening gun, play a vital role in this stage.

Steam Injection and Preheating
Steam is injected into the solid transfer mold for further preheating. This step raises the mold’s temperature and strengthens the apparent fusion degree of the product, ensuring a solid and consistent EPS product.

Core Heating and Penetration
The core and internal fusing properties of the products are improved through thorough heating. This stage is critical for enhancing the product’s structural integrity, although it can lead to increased steam consumption.

Two-Way Heating
To further enhance the heating effect and improve the product’s surface quality, two-way heating is employed. This method ensures even heat distribution and a high-quality finish on the EPS product.

Return Temperature and Insulation
Utilizing residual heat, all valves are closed to maintain the mold’s temperature. This process benefits the surface fusion property of the product and saves energy, particularly steam.

Precooling
During precooling, the water cooling valve is opened, and the drain valve is closed. This stage speeds up product cooling, shortens the overall cooling time, and improves molding speed.

Water Cooling
Water cooling involves opening both the water cooling and drainage valves. The combined effect of water and air cooling ensures efficient temperature reduction of the EPS product.

Vacuum Cooling
Finally, vacuum cooling is implemented. The vacuum valve is opened, and the vacuum pump is activated to remove residual heat and water. This step also aids in demolding by creating a negative pressure inside the mold.
