Automatic batch EPS pre-expander is a kind of equipment which can automatically complete the procedures of measuring, loading raw material, heating, expanding and discharging. It is an ideal equipment for large and medium enterprises to produce light foamed products. The advantages of automatic batch EPS pre-expander are as follows: 

 

-It is much faster than manual expanding, which means that you can produce more products in a shorter amount of time.

 

 -It is very consistent, so you can be sure that each product will be the same as the last one. 

 

-It is less labour intensive, so you will not need to hire as many staff to operate it. Overall, using an automatic batch EPS pre-expander can help to improve your business in a number of ways. If you are thinking about investing in one, then these are just some of the advantages that you can expect.

 

1. The whole process is controlled by computer, which is easy to operate; 

 

2. The structure of the machine is reasonable and the performance is stable; 

 

3. The heating system adopts hot air cycle heating, which can save energy and improve production efficiency; 

 

4. Fully closed expansion chamber and efficient filter system can reduce pollution and improve working environment; 

 

5. Pneumatic discharge door design can realize fully automated production line operation.

 

The EPS Pre-Expander is a batch type machine that automatically expands raw material beads (EPS/EPP) through steam heating, and is widely used as the first step in the production process of expanded bead products. The pre-expander is a key machine in the entire production line, and its performance directly affects the product quality and production efficiency of the whole line.

 

 

 

 

Types of Automatic batch EPS pre-expander

 

machines There are two main types of EPS pre-expanders: - Continuous pre-expanders - Intermittent pre-expanders Continuous EPS pre-expanders are always in operation, meaning they can operate 24 hours a day, 7 days a week. The EPS beads are continuously fed into the machine and expanded in a controlled manner. These machines are generally used for high volume applications. 

 

Intermittent EPS pre-expanders are only operated when needed. The EPS beads are fed into the machine and expanded in a batch process. These machines are generally used for lower volume applications or when there is a need for more flexibility (e.g., different bead sizes).

 

EPS is widely used as building insulation material, but it is also used for many other purposes, such as packaging and flotation devices. It is a lightweight, rigid foam that has excellent thermal insulation properties.

 

 EPS is made from expanding polystyrene beads. The beads are expanded with steam and then molded into the desired shape. There are two types of EPS pre-expanders: batch and continuous. Batch pre-expanders are the most common type. 

 

They expand the beads in batches in a separate chamber before they are fed into the molding machine. Continuous pre-expanders expand the beads as they are fed into the molding machine.

 

Tips for choosing Automatic batch EPS pre-expander

 

machine Here are some tips that may help you choose the right Automatic batch EPS pre-expander machine for your needs:

 

 1. Know the different types of machines. There are two main types of EPS machines, namely, the automatic and semi-automatic machines. Each has its own set of advantages and disadvantages. 

 

2. Consider the capacity of the machine. The capacity of the machine should be able to accommodate your production volume. If you have a small business, a semi-automatic machine may suffice. On the other hand, if you have a large-scale business, an automatic machine would be ideal.

3. Consider the features of the machine. The features of the EPS pre-expander will determine its efficiency and productivity. Some features to look for include automatic loading and unloading system, foam density control, temperature control, and others.

 

 4. Consider the price of the machine. The price is usually determined by its features and capacity. Compare prices from different suppliers before making a purchase.

How to get low density beads--EPS Pre-expander is ...

As we all know EPS Pre-expander is a device that makes EPS beads expand and increase in size and make foam plastics by heating. The reactor of the existing foaming machine is a single-layer structure. In order to keep warm, the asbestos felt and stainless steel sheet are wrapped on the outer wall of the reactor. The heat preservation effect is poor, and the foaming effect will be affected. Therefore, a foaming machine with good thermal insulation effect is badly needed.

EPS Pre-expander plays a main role in getting low density beads.

Our EPS Pre-expander Characteristics&#;
