Equipment Composition & Performance Overview

1. EPS Pre-Foaming Machine: The EPS Foam Production Line is equipped with a high-efficiency closed-loop constant pressure pre-foaming machine, adopting negative pressure automatic feeding and electronic weighing technology to automatically control pre-foaming temperature and density. The temperature difference inside the barrel is controlled within ±1%, and the density error of EPS beads is less than ±3%, laying a solid foundation for subsequent molding processes.

2. Molding and Curing System: The equipment is equipped with a high-precision EPS molding machine, which can achieve precise molding of EPS foam products of various shapes and specifications through mold matching. The curing system adopts high-temperature and high-pressure curing technology, ensuring that the foam products have a uniform internal structure, high compressive strength, and low water content (less than 2%), which significantly improves product durability.

3. Drying and Conveying System: The equipment is equipped with a fluidized drying bed, which can automatically screen and dry foamed EPS beads to effectively remove excess moisture. Then, the beads are accurately transported to the curing silo through an automatic conveying device, realizing full-process automated operation and ensuring the stability and continuity of subsequent molding processes.

4. Curing Silo: Connecting the pre-foaming machine and the molding system, it is equipped with a large-capacity curing silo with constant temperature and moisture retention functions. It can fully cure the pre-foamed EPS beads (curing time can be flexibly adjusted), ensuring uniform expansion of the beads and further improving the molding quality and density consistency of foam products.

5. Demolding System: After molding and curing, an automatic demolding device is adopted, combined with a high-temperature resistant mold release agent spraying system, to achieve smooth demolding without mold sticking. It can not only effectively protect the mold from damage but also greatly improve production efficiency, reduce the labor intensity and product loss of manual demolding, and connect with the molding process to achieve an automatic closed-loop operation.

6. Electrical Control System: As the "central nervous system" of the equipment, it adopts a PLC intelligent control system combined with a high-definition touch screen. It can accurately control key parameters such as temperature, pressure, and time for each process, including pre-foaming, drying, molding, and curing, supporting parameter memory and one-click call. With simple operation, it can realize unattended production, reduce labor costs, and ensure the efficient and stable operation of the entire set of equipment.

Main Characteristics

1. Precise Density Control: The equipment adopts an imported high-precision pilot pressure reducing valve and photoelectric level control technology, which can accurately control the pre-foaming density within the range of 18-30g/L, with a batch stability error of ≤±1g/L, ensuring consistent performance of each batch of products and fully meeting the quality requirements of high-end packaging, building insulation and other fields.

2. Strong Molding Flexibility: Adopting a modular mold design, the equipment can be equipped with different specifications of molds according to customer needs. It can produce various shapes of EPS foam products, such as foam boxes, packaging liners, and thermal insulation boards, which can flexibly meet the personalized production needs of automotive KD parts packaging, food cold chain, building insulation and other fields.

3. Energy-Saving and Environmental Protection: Adopting a closed-loop pre-foaming design, the equipment saves more than 50% of energy compared with traditional continuous pre-foaming machines. The produced EPS foam products are recyclable, in line with the global ESG environmental protection concept, with no harmful emissions during the production process, adapting to the development trend of green production and enhancing the core competitiveness of the equipment.

4. High Foaming Efficiency: On the basis of precise density control, the pre-foaming machine adopts high-efficiency mixing and heating technology, enabling uniform and fast bead foaming. The single-batch pre-foaming capacity can reach 500-1000kg, which greatly improves production efficiency, perfectly adapts to the large-scale production needs of manufacturers, and forms a coordinated advantage with the precision and flexibility of the equipment.

5. High Product Forming Precision: Combined with the advantage of strong molding flexibility, the molding machine adopts high-precision mold positioning technology with high clamping precision. The size error of foam products is ≤±0.3mm, with a smooth surface, no bubbles and no material shortage. It not only inherits the high-precision characteristics of the equipment but also meets the strict quality requirements of high-end packaging and thermal insulation fields.

6. Adaptable to Multiple Raw Materials: Inheriting the flexibility advantage of the equipment, it can be compatible with different specifications of EPS raw materials (particle size 0.5-3mm). The raw material ratio can be flexibly adjusted according to product performance needs to produce foam products with different densities and performances, further expanding the application scenarios of the equipment and meeting personalized production needs in multiple fields.
