Styrofoam Compactor – Essential Tools for Reducing Foam Volume

A Styrofoam compactor is a specialized machine designed to reduce the volume of polystyrene Styrofoam waste by applying mechanical pressure. By compacting loose foam into dense blocks, it achieves a volume reduction of up to 90%, transforming bulky waste into manageable materials for easier storage, transportation, and recycling.

Introduction of Styrofoam Compactor

The स्टायरोफोम कम्पेक्टर is an industrial equipment that uses mechanical pressure or hydraulic drive to compress EPS foam at room temperature. Different from hot press, which needs to be heated and melted, it relies on physical extrusion to realize volume reduction, and is suitable for temperature-sensitive or waste material processing scenarios that do not require material modification.

Styrofoam Compactor Working Principle

• Feeding: Loose Styrofoam is inserted into the compactor’s hopper.
• Compression: A hydraulic or mechanical press crushes the foam under high pressure.
• Ejection: Compacted foam is expelled as dense blocks, which can be easily stacked or sold to recycling facilities.

Two Types of Polystyrene Compactor

There are two types of cold presses: vertical cold presses and horizontal cold presses. We offer different types to meet your multiple needs.

Horizontal EPS Foam Compactor

• Horizontal EPS foam compactor can accommodate larger volumes of scrap (e.g. full boxes of foam packaging)
• Its inlet can be directly connected to a horizontal conveyor belt. Foam scrap can be fed directly into the horizontal press via the belt conveyor, reducing manual handling.
• In addition, it avoids the uneven accumulation of material caused by the gravity drop of the vertical model.

Vertical EPS Foam Compactor

• The vertical EPS foam compactor’s vertically compact design is suitable for scenarios where space is limited in the storage area or for three-dimensional layouts where a multi-story plant is required.
• It’s an enclosed vertical compression chamber with a dust extraction interface that reduces dust spillage compared to horizontal models.

EPS Foam Compactor Features and Advantages

• Low Temperature Processing: PS foam is a heat-sensitive material, which is easy to soften and deform or even melt at high temperatures. Cold pressing can avoid the size distortion, surface cracking or chemical deterioration of EPS caused by temperature change.
• Uniform and stable pressure: EPS foam has low density and loose texture, cold pressing can provide uniform force hydraulically or mechanically to ensure that the foam is uniformly molded under pressure, avoiding rupture of foam cell walls due to excessive pressure.
• Improvement of material utilization rate: Cold pressing can be used for secondary pressing and recycling of edges and scraps (e.g., cold pressing of crushed foam into blocks), and the material utilization rate can be increased to more than 90%.

Final Output of Foam Compactor Machine

After EPS foam waste is pressed by a cold press with high pressure, it forms compact and regular blocks, which greatly reduce the volume compared with loose waste and are convenient for transportation and recycling.

This kind of foam block retains the basic cushioning performance, can be directly used as logistics cushioning or horticultural filler materials, can also be crushed into new products after the second cold pressing, not only to solve the problem of white pollution, but also to reduce the cost of production, it is the key form of recycling of foam resources in the circular economy.
