How an EPS Screw Compactor Works

Sort the foam, break it into manageable pieces, then compress and collect the output as a compacted block stream.

Prepare & Feed EPS

Separate EPS from other plastics and remove tape, metal and loose waste. Empty and clean used boxes, then feed pieces sized to the machine opening.

Crush the Foam

The crushing section breaks bulky packaging into smaller fragments. Consistent loading helps maintain an even supply to the compression screw.

Compress with Screw Pressure

The screw conveys and compresses the fragments, reducing the air-filled volume through mechanical pressure. The process does not use a thermal melting stage.

Collect & Stack Blocks

Collect the formed output, check block integrity and prepare it for storage or transport. Match block handling and batch cleanliness to the receiving recycler.

Make EPS Collection and Transport More Practical

Reduce Loose Foam Storage

Convert bulky packaging and offcuts into compact blocks. Measure the reduction against your loose feed volume to plan storage space and collection frequency.

Use a Mechanical Recycling Route

Cold pressing removes the need for a melting stage. Select the screw compactor around feed behavior, block stability and the available electrical supply.

Prepare Blocks for a Recycler

Keep identified EPS batches together and confirm the required block form with your buyer. Compaction prepares the material for transport and further PS processing.

From Loose Foam to Stackable Blocks

The pictured blocks show EPS after mechanical cold compaction. This compact form makes loose foam easier to store and collect for downstream recycling. Block dimensions, density and handling strength depend on the feed material and machine setup.

Check block integrity before moving and stacking
Keep identified EPS batches separate from other foams
Agree block size and cleanliness with the receiving recycler
Plan pallet handling and collection around the actual block weight

EPS Waste Streams for Cold Compaction

Select the machine around the source, cleanliness, dimensions and daily volume of your EPS foam.

Appliance & Electronics Packaging
Molded EPS protectors and cushioning inserts from unpacking, retail and distribution operations, after removal of tape, film and other packaging materials.
EPS Fish Boxes & Produce Containers
Sorted polystyrene boxes after emptying and cleaning. Free liquids and food residues should be removed before evaluating feeding and block quality.
Foam Production & Cutting Scrap
Known-grade EPS offcuts, rejected molded pieces and clean factory scrap. Record the loose bulk density and largest pieces when selecting the feed opening.
Sorted Collection-Center EPS
Source-separated packaging collected for volume reduction before shipment. Keep incompatible foams and heavily contaminated material out of the EPS stream.

EPS Cold Press Machine Questions

Does an EPS cold press melt the foam?

No. The RTM-CP series uses crushing and screw pressure to form compacted EPS blocks without a thermal melting stage. Friction can still generate heat during mechanical processing; cold pressing describes the compaction method.

How do I choose between RTM-CP50, RTM-CP100 and RTM-CP200?

Their listed EPS throughput ranges are 40–50, 80–100 and 150–200 kg/h respectively. Compare these with your daily weight, shift hours, loose foam density and piece size. The feed opening and loading method also affect the practical processing rate.

What compression ratio will my EPS achieve?

Volume reduction varies with the starting foam density, contamination, feeding and block formation. Use representative material to measure loose input volume and compacted output volume on the same basis, then check that the blocks hold together during handling.

Can I feed wet fish boxes or mixed foam directly?

Empty and clean EPS boxes and remove free liquids before compaction. EPE, EPP, XPS, polyurethane and mixed foams require their own suitability assessment. Keep the EPS stream sorted and describe its actual condition when requesting a proposal.

Does the machine produce recycled polystyrene pellets?

The cold press produces compacted blocks, not finished pellets. A receiving recycler can assess the blocks for further preparation and suitable PS extrusion or pelletizing. Agree cleanliness and output requirements with that recycler before selecting the machine.

Should I choose cold compaction or hot melting?

Start with the output your recycler accepts and the utilities at your site. Cold compaction produces mechanically compressed blocks. Hot melting produces fused material and adds heating, cooling and extraction requirements. Compare actual feed trials and operating needs for both routes.

Can the electrical system and motor voltage be customized for our local power supply?

Yes. All motors, electrical cabinets, and control panels are customized to match your country industrial power standard, including 3-Phase 208V, 220V, 380V, 400V, 415V, 440V, 460V, or 480V at 50Hz or 60Hz. We use globally certified components from Siemens, Schneider, and ABB for reliability and easy international maintenance.

Do you test the machine with actual plastic material before shipment?

Yes. Every machine undergoes a comprehensive factory dry run and mechanical load test before packing. Clients are welcome to supply sample plastic feedstock to our testing workshop for live trial processing, and we provide complete high-definition video inspection records prior to final dispatch.

How do you handle overseas installation, commissioning, and operator training?

We provide complete engineering documentation including 2D/3D plant layout drawings, electrical schematics, and English operating manuals. For turnkey recycling lines, our experienced field engineers can travel on-site globally to guide installation and train your team, backed by 24/7 video technical support.

What warranty is provided, and how quickly can spare parts be delivered abroad?

We provide a 12-month warranty covering structural and mechanical components. Critical wear parts (such as blades, screens, seals, and heating elements) are stocked continuously and can be dispatched via international express air courier (DHL/FedEx) within 48 hours to minimize production downtime.
