EPS foam melting machine is a kind of comprehensive equipment that combines the functions of foam crushing and melting processing. It crushes waste Styrofoam into small particles(equivalent to a foam crusher), then melts these small particles and plasticizes the foam with a screw to form reusable plastic lumps or pellets. The machine can achieve a compression ratio of up to 90 times, which greatly reduces the storage and transportation costs of EPS foam and is a good choice for recycling.
raw materials for EPS foam melting machine
EPS hot melting recycling machines are typically able to process many types of raw foam materials such as polystyrene foam (EPS), polyethylene foam (EPE), and polypropylene foam (EPP).
Polystyrene foam is widely used as insulation and product protection materials during transportation. The transportation of home appliances and fragile goods requires polystyrene foam materials to prevent product damage. This material often appears in our lives in the form of furniture packaging, building materials, roof insulation, fish boxes, and preservation of agricultural and fishery products.
The density of foam board is generally 10-45kg/m³. Due to its lightweight and large volume, the transportation cost is greatly increased. Based on our factory’s rich experience, we have two ways to reduce the volume of foam: one is to use a compressor for cold pressing, and the compression ratio is generally 1:50; the other is to use a hot melt machine for hot melting treatment, melt the foam and cool it into blocks, to achieve the change of volume density.
final foam lumps show
The finished products produced by the EPS foam melting machine have high density and a volume reduction of more than 90%, which significantly reduces storage and transportation costs. The finished products can be reprocessed into a variety of plastic products to achieve resource reuse, saving up to 70% of waste disposal costs for enterprises each year and improving overall economic benefits. Taking a large plastic weaving factory as an example, using 30% recycled raw materials can reduce costs by 80,000 to 200,000 US dollars, significantly reducing production costs.
recycling steps of EPS Foam Densifier
- First, the heating system is started to preheat the screw to the rated temperature, and then the waste Styrofoam is thrown into the hopper of the machine.
- Then a pre-crusher with two or four rotating cutter shafts breaks it into 10-50mm pieces, which are forced into the extruder system by the screw.
- The heating element heats the foam and melts it to the right temperature. EPS foam is plasticized into a homogeneous melt through the extrusion system and is continuously extruded by the screw in the process.

Foam crushing hot melt machine precautions
When using the EPS foam melting machine needs to pay attention to the following matters, and care and maintenance of the foam crushing hot melt machine is to ensure that the equipment is for a long time and efficient operation of the key.
- Equipment maintenance: regularly clean the blades, check the heating system, and lubricate the mechanical parts, to ensure normal operation.
- Replacement of worn parts: for parts that are easy to wear out, such as the blades, replace them in time to ensure the treatment effect and the life of the machine.
- Material adaptability: ensure that the foam material put into the machine meets the specifications and requirements of the machine to avoid damage to the equipment.
- Temperature control: during operation, adjust the appropriate hot melt temperature according to different foam materials to ensure the treatment effect.
- Preventing clogging: pay attention to preventing the inlet of the EPS foam melting machine from clogging to ensure smooth material flow.
successful cases
Most companies in the recycling industry will face the situation of recycling plastic foam. One of our customers from Saudi Arabia runs an assembly plant for electronics and appliances, which generates a lot of waste foam packaging materials. Because their old compactor was too slow and not working properly, they chose a new EPS foam melting machine to increase their recycling rate.
In the past year, they have saved at least $15,000 in landfill costs, made more than extra profits by selling the melted foam, and increased warehouse efficiency by at least 30%.
