Its basic material is polystyrene, which is processed by adding a physical foaming agent to form a material with the advantages of light weight, excellent thermal insulation, strong impact resistance, waterproof and moisture-proof. The preparation process of EPS foam usually includes mixing polystyrene resin with a foaming agent, foaming it by heating and pressurizing, and finally making a foam plastic with a closed-cell structure. EPS foam is widely used in various fields due to its unique properties. In the field of construction, it is often used as a material for external wall insulation system (EWI), roof insulation, ground insulation, cold storage, refrigerated trucks, ship insulation, pipeline insulation, heating equipment insulation and other projects. In the field of packaging, EPS foam is widely used in shockproof packaging materials for mechanical equipment, instruments and meters, household electrical appliances, handicrafts and other fragile and valuable products, as well as the packaging of fast food.

When the EPS foam in the feed pipe 5 is input, the linear module 6 starts again and drives the push column 9 to move to the left. At this time, the EPS foam in the feed box 3 flows into the feed pipe 5 again.
