Up to 90:1 Volume Reduction
EPS Foam Melting Machine
This EPS foam melting machine — also called a Styrofoam melter or EPS hot melt machine — transforms bulky polystyrene foam into dense, valuable ingots through continuous hot-melt densification. Slash storage costs by up to 90%, simplify logistics, and turn EPS and Styrofoam waste into a profitable reusable resource.
Key Advantages
Efficiently minimize waste volume and create new revenue streams with our advanced hot-melt densification process.
Exceptional 90:1 Densification Ratio
Achieves an outstanding volume reduction of up to 90:1, converting a full truckload of loose EPS foam into a single pallet of dense ingots. This drastically cuts storage space by 90% and slashes transportation costs.
Creates Valuable Resources
Transforms waste foam into dense ingots — a highly sought-after commodity for plastic recycling industries worldwide.
Energy Efficient Operation
Automatic temperature control system ensures efficient melting without wasting energy or overheating materials.
Compact Footprint, High Throughput
Features a compact mechanical design suitable for facilities with limited floor space, yet delivers stable throughput from 40 kg/h to 200 kg/h depending on the model. The integrated crusher-melter design eliminates the need for separate pre-processing equipment.
Environmental Protection & Compliance
Effectively reduces white pollution and minimizes landfill waste. The sealed melting process contains fumes, and our systems support add-on exhaust filtration to meet local environmental regulations and promote a circular economy.
Precise Temperature Control
Maintains ideal melting conditions to prevent burning or degradation, preserving material quality for high-value recycling.
How It Works
From loose waste foam to dense, sellable blocks in four automated steps.
Feeding & Crushing
Waste EPS foam is loaded by an optional conveyor belt for continuous auto-feeding, then a dual-shaft crushing system breaks it into smaller, manageable pieces for efficient melting.
Heating & Melting
Crushed foam enters the heated barrel where a rotating screw conveys it through a precise temperature zone, melting it into a viscous liquid.
Extrusion & Forming
The molten polystyrene is continuously extruded through a die head, forming dense, solid ingots or blocks with a uniform shape.
Discharge & Collection
Densified blocks are cooled and discharged automatically. The compact ingots stack neatly on pallets for easy shipping and sale to recyclers.

Performance You Can Expect
What the EPS foam melting machine delivers in day-to-day operation.
Up to 90:1 Volume Reduction
A full truckload of loose EPS is condensed into a single pallet of dense ingots, cutting storage space and outbound transport volume by roughly 90%.
40–200 kg/h, One Operator
Three models cover 40–50, 80–120, and 180–200 kg/h. Continuous auto-feeding and temperature control let a single operator run the line without constant attention.
