The process of EPS hot melting involves heating the EPS foam to its melting point, which is around 180-220°C (356-428°F), depending on the specific type of EPS. The melted EPS can then be molded or processed into new products or shapes.

There are different types of machinery and equipment used for EPS hot melting, including:

1. EPS Melting Machines: These machines are designed to efficiently heat and melt down EPS foam. They often come with a feeding mechanism to load the EPS waste, a heating chamber, and an extrusion system to push the melted EPS out.
2. EPS Densifiers: EPS densifiers are machines that compact and melt EPS foam to reduce its volume, making it easier for storage and transportation. They use heat and pressure to densify the foam.
3. Extruders: Extruders are commonly used in EPS recycling processes. They melt the EPS and then extrude it into various forms, such as pellets or blocks, which can be used for manufacturing new products.
4. Melted EPS Applications: The melted EPS can be used to produce various products, such as plastic pellets for manufacturing, picture frames, construction materials, and more.
5. Environmental Considerations: EPS recycling and hot melting can be environmentally beneficial as they reduce the amount of EPS waste going into landfills or the ocean. However, the process requires energy and proper handling to prevent emissions of harmful gases. It’s important to consider proper ventilation and emission controls when using EPS hot melting machinery.

Please note that specific machinery and technologies can evolve over time, so it’s recommended to consult with manufacturers or experts in the field for the most up-to-date information and equipment options for EPS hot melting.
