About EPS Pre-Expander

EPS Pre-Expander is a device that is commonly used in the production of expanded polystyrene products. The EPS Pre-Expander increases the output of an EPS production line by up to 30%. It does this by heating the polystyrene beads to just below their melting point, then forcing them through a small hole, called a die, under high pressure. This process creates very small bubbles in the polystyrene, which are then expanded by blowing hot air through them.

EPS Pre-Expander advantages: 

Increased Capacity; Reduced Costs; Improved Quality 

China EPS Pre-Expander

1. EPS Pre-Expander is a device that helps in the expansion of EPS (Expanded Polystyrene) sheets.

2. EPS Pre-Expander is easy to operate and does not require much maintenance.

3. It does this by pressurizing the air in the system and forcing it through the expansion chamber, which causes the expansion of the EPS foam.

4. This increased expansion causes the foam to be expelled from the nozzle at a higher velocity and with more force.

5. This gives the user a greater range and more power when using EPS foam.

Specification:

1. This machine applies PLC and touch screen, automatic feeding, electronic weighing, temperature control, material level control to realize automatic and continuous production.

2. Electronic weighing system and material level control system, Korean vibration sensor, proportional valves of steam and compressed air to ensure the density of the foamed beads tolerance within 1%.

3. Density range 12~120g/l, used to make beads for helmet, beehives and other high destiny products.
