What is EPS Pre-expander machine ?

EPS Pre-expander machine

The EPS pre-expander machine is a device used to increase the size of an EPS foam block. The machine works by heating the foam block until it is soft, then expanding it using a vacuum.


This process increases the size of the foam block, making it easier to work with. The EPS pre-expander machine is a valuable tool for manufacturers who use EPS foam in their products.


1. EPS (Expanded Polystyrene) is a lightweight, rigid plastic that is used for a variety of applications, including shipping and packaging.


2. EPS can be recycled, but it is also often disposed of in landfills.


3. A pre-expander machine can be used to increase the size of EPS pellets before they are melted down and formed into new products. The EPS pre-expander machine is used to increase the size of the foam beads before they are injected into the cavity of a product.


This increases the speed and production of the manufacturing process. The machine has two hoses: one for the input of foam beads and one for the output of expanded foam beads. The speed and production of the machine can be adjusted to accommodate the needs of the manufacturer.


The EPS Pre-expander machine is a unique piece of equipment that has the ability to increase the size of an EPS foam block by up to 400%.


This is done by heating the foam and then forcing it through a series of nozzles. The end result is a block of foam that is significantly larger than the original block.
