What you should know about eps pre-expander machine

 

An EPS pre-expander machine is a type of machinery used in the production of expanded polystyrene (EPS) products. EPS pre-expander machines are used to expand EPS beads into larger more manageable pieces that can be used in the production of various EPS products.

 

What is eps pre-expander machine

 

The machine consists of four main parts: an expansion chamber a heating system a cooling system and a controls system. The expansion chamber is where the polystyrene beads are expanded. The chamber is pressurized with steam which heats the beads and causes them to expand. The cooling system then cools the beads so they can be solidified and molded into their desired shape.

 

An EPS pre-expander machine is a type of machinery used in the production of expanded polystyrene (EPS) products. EPS products are made by expanding polystyrene beads with steam and the pre-expander machine is used to expand the beads before they are placed in an mold. The pre-expander machine typically has a hopper for holding the beads a steam chamber for expanding the beads and a cooling chamber for cooling the expanded beads. The expanded beads are then transferred to an mold where they are formed into the desired shape.

 

Features of eps pre-expander machine

 

EPS pre-expander machine is one of the most important machines in EPS production line. It is used to expand and heat the raw material (EPS beads) to a certain degree of expansion and temperature so that the raw material can be sent to the next process (EPS block molding machine) for molding. The features of eps pre-expander machine are as follows:

 

1. PLC control system with touch screen panel easy to operate;

 

2. Automatic feeding system includes quantitative feeder and conveyor belt;

 

3. The pre-expansion chamber is made of stainless steel with good thermal insulation performance and long service life;

 

4. The heating system uses steam or hot water as the heat source which is more energy-saving than traditional heating methods;

 

5. Equipped with over-temperature and over-pressure protection devices safe and reliable;

 

The eps pre-expander machine is used to expand raw EPS beads into larger beads. The expanded EPS beads have a lower density and are more resistant to crushing. The eps pre-expander machine is also equipped with a steam heating system which can quickly heat the raw EPS beads and make them easier to expand. The eps pre-expander machine is also equipped with a pressure gauge and a temperature controller which can help the operator to better control the expansion process.
