EPS foam cold pressing machine is an essential piece of equipment in the EPS foam granulating line and is divided into horizontal EPS foam compactor and vertical EPS foam compactor. EPS foam compactor crushes large pieces of EPS foam and compacts the crushed EPS into blocks to facilitate the recycling of EPS block waste.
Introduction of EPS foam cold pressing machine
EPS foam is widely used in various industries because of its thermal insulation, shock resistance, and drop resistance, and is often referred to as polystyrene/ polystyrene. This material is usually found in our lives in furniture packaging, fish boxes, building materials, EPS trimmings, and more.
EPS foam cold pressing machine specialize in compressing various EPS materials and can reduce the volume of EPS foam by up to 40:1. EPS foam cold pressing machine can easily compact plastic foam, effectively avoiding environmental pollution and facilitating the transport of styrofoam materials.
EPS/EPE foam is compressed by the foam cold press, resulting in a denser, square foam, which reduces the volume of the foam and makes it easier to transport and store.
Raw materials & compacted results
The biggest problem with polystyrene foam is its lightweight and large size. eps foam is dispersed and difficult to transport.
The compacted foam increases density and decreases volume, which is convenient for stacking, storage and transportation.
Principle of EPS foam compactor
The EPS foam compactor is a machine for extruding dense foam blocks based on the principle of spiral rotation to generate pressure. The foam compactor processes the raw material by cold pressing and compression.
Recycling steps of EPS foam compactor
- Put the EPS foam to be processed into the hopper for crushing.
- Crushing large pieces of EPS foam into smaller pieces.
- Compaction of the crushed EPS foam by extrusion technology – EPS foam is compressed using extrusion and hydraulic technology.

Horizontal EPS foam compactor and vertical EPS foam compactor
The horizontal EPS foam compactor has the same function as the vertical EPS foam compactor, squeezing and shrinking large volumes of foam to facilitate transport. And the feed opening is parallel to the ground, which helps the staff to save their strength.
Horizontal EPS foam compactor is suitable for extruding various EPE/EPS foam products such as fast food boxes, foam packaging materials, insulation materials, and waste plastic products such as foam materials.
Similar to the horizontal EPS foam compactor, the vertical EPS foam compactor has a high compression ratio, does not require the addition of chemical materials for cold pressing, and is odorless.
