Product Description
The EPS Hot Melting Machine is an advanced foam recycling solution designed to convert low-density expanded polystyrene (EPS) waste into compact, high-density blocks through thermal melting and compression. Widely used by recycling companies, municipal waste centers, seafood packaging processors, appliance manufacturers, logistics warehouses, and plastic recyclers, this machine significantly reduces storage and transportation costs while increasing the value of recycled EPS materials.
At Zhangjiagang Chenxing Machinery Co., Ltd., we have extensive experience in designing and manufacturing recycling equipment for plastic processing industries worldwide. Our EPS Hot Melting Machine combines crushing, melting, compression, and densification into a single integrated system, helping businesses achieve cleaner production, lower logistics expenses, and improved recycling profitability.
Expanded Polystyrene (EPS), commonly known as foam packaging, presents unique recycling challenges:
Extremely low bulk density
Occupies large storage areas
High transportation costs
Difficult handling and collection
Low economic value before densification
Without proper densification equipment, transporting EPS waste often costs more than the material itself.
The Chenxing EPS Hot Melting Machine solves these challenges by reducing foam volume by up to 90%, converting loose foam into dense blocks suitable for resale and further pelletizing processes.
An EPS Hot Melting Machine, also known as:
EPS Melter
EPS Densifier
Foam Melting Machine
EPS Recycling Machine
Styrofoam Densifier
EPS Compactor
is a thermal recycling system that melts and compresses waste EPS foam into dense ingots.
Unlike cold compaction systems, the hot melting process achieves higher densification ratios and produces more uniform output blocks, making transportation and downstream recycling significantly more efficient.
The machine is suitable for processing:
Packaging foam
Appliance packaging
Protective foam inserts
Electronics packaging
Manufacturing offcuts
Production rejects
Foam molding waste
Seafood boxes
Fish containers
Fresh produce trays
Insulation boards
Building foam waste
Demolition EPS materials
The EPS Hot Melting Machine integrates crushing, heating, compression, and discharge into a continuous operation.
Waste EPS foam is manually or automatically fed into the hopper.
Multiple crushing shafts shred bulky foam into smaller pieces.
Benefits include:
Stable feeding
Uniform particle size
Improved melting efficiency
A heavy-duty screw transports crushed foam into the heating chamber.
Electric heating zones gradually soften and melt the EPS material.
The controlled heating process ensures:
Uniform melting
Stable output quality
Reduced energy waste
The molten material is compressed into dense blocks.
Volume reduction can reach:
Up to 90%
High-density EPS ingots are continuously discharged and cooled for storage, transportation, or further recycling.

The machine reduces foam volume by approximately:
80%–90%
This dramatically lowers:
Warehouse requirements
Transportation costs
Handling expenses
Built-in crusher eliminates the need for a separate shredding machine.
Advantages:
Compact footprint
Lower investment cost
Simplified operation
Independent heating control provides:
Stable melting temperature
Consistent product quality
Energy-efficient operation
The reinforced screw system ensures:
Continuous material flow
Reliable densification
Long service life
Optional PLC touchscreen system enables:
Temperature monitoring
Motor protection
Fault alarms
Automatic operation
The machine frame is designed for industrial environments:
Heavy-duty steel structure
Wear-resistant components
Easy maintenance access
Because foam is mostly air, transportation is expensive.
After densification:
More material per truckload
Lower fuel costs
Improved logistics efficiency
Densified EPS blocks command higher market value than loose foam.
This improves:
Recycling profitability
Material recovery rates
ROI on recycling operations
Loose EPS often creates:
Dust
Static cling
Storage problems
Compact ingots are easier to handle and store.
EPS densification contributes to:
Waste reduction
Circular economy initiatives
Landfill diversion programs
Corporate sustainability targets
