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 fed into the hopper, where 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.
Application Scenarios
Our EPS foam melting machines serve a wide range of industries that generate polystyrene waste.
Logistics & Packaging
Process EPS packaging inserts, protective corners, and cushioning materials from warehouses and distribution centers.
Seafood & Food Industry
Densify EPS fish boxes, food trays, and insulated containers used throughout the cold chain and food service industry.
Construction & Insulation
Recycle EPS insulation boards, ICF block offcuts, and construction waste foam from demolition and renovation projects.
Electronics & Appliances
Handle protective foam packaging from TVs, refrigerators, washing machines, and other consumer electronics.
Manufacturing Plants
Process EPS production trimmings, reject parts, and off-spec foam from molding facilities for in-house recycling.
Recycling Centers & MRFs
Central processing of collected EPS waste from municipal and commercial recycling programs, maximizing material value.

Frequently Asked Questions
Everything you need to know about EPS foam melting and densification.
This machine is primarily designed for EPS (Expanded Polystyrene) foam, commonly found in packaging materials, fish boxes, insulation boards, and protective packaging. It effectively densifies these loose materials into solid ingots. Some models can also handle EPE (Expanded Polyethylene) and XPS (Extruded Polystyrene) with minor adjustments.
Our hot-melt densifier achieves a remarkable volume reduction ratio of up to 90:1. This means a full truckload of loose EPS foam can be compressed into a single pallet of dense ingots, dramatically reducing storage and transportation costs.
The system uses PID-controlled heating elements along the barrel to maintain optimal melting temperatures. This prevents overheating (which degrades plastic properties and generates fumes) and underheating (which causes incomplete melting). The result is consistent, high-quality ingots that fetch premium market prices.
We offer three models to match different waste volumes: the GL-HM100 (40–50 kg/h) for smaller operations, the GL-HM200 (80–120 kg/h) for medium-scale facilities, and the GL-HM400 (180–200 kg/h) for high-capacity industrial applications.
Every EPS foam melting machine includes a comprehensive 1-year limited warranty covering all mechanical components against manufacturing defects. We provide full installation guidance — either remotely via video call or on-site by experienced engineers — plus ongoing operational consultancy to ensure your recycling line runs at peak efficiency.
