Plastic foam is widely used, but it is not easy to transport and store, and thus plastic foam is often used once, resulting in a large amount of plastic foam waste. Before recycling plastic foam, it is usually necessary to crush the plastic foam to make it granular, so that it can be quickly and uniformly melted in subsequent operations, preventing uneven melting of plastic foam due to uneven heating.
