Foaming Beads Machine Auto Lost Foam Pre-expander

The Foaming Beads Machine Auto Lost Foam Pre-expander is a new and innovative way to increase foam production. This machine uses a lost foam system to help increase the production of foam. This system helps to reduce the amount of lost foam, which in turn reduces the amount of waste that is created during the production process.

About EPS Pre-Expander:




Auto Lost-Foam Pre-Expander pre-expanders  are devices that selectively expand or contract a gas or liquid prior to its use in a process. By doing so, the device can reduce the amount of energy needed to achieve the desired result. Pre-expanders are frequently used in industrial processes such as metalworking and chemical manufacturing.


Auto Lost-Foam Pre-Expander pre-expanders  are a new type of compressor that can be used to reduce the noise and emissions produced by gas turbines and other industrial machines. The pre-expander continuously expands the air before it is sent into the compressor, reducing the amount of noise and emissions produced. This technology is currently being used in a number of applications, including aircraft engines and power plants.


A  Auto Lost-Foam Pre-Expander pre-expander  is a machine that helps reduce energy consumption before a furnace begins to operate. By decreasing the amount of energy needed to start the furnace, this machine can help conserve energy and avoid expensive repairs.


Auto Lost-Foam Pre-Expander pre-expanders are a type of compressor that can be used in order to increase the efficiency of an engine. This type of compressor is able to work continuously, which helps to reduce the amount of time that is needed in order to reach the desired compression level. Additionally, Auto Lost-Foam Pre-Expander pre-expanders are frequently used in diesel engines in order to help improve fuel economy.


Advantages of EPS Pre-expander Machine:

1. Steam system: accurate pressure reducer to keep stable and accurate steam, ensure material variation;

2. Pressure control: Pressure sensor with muli-steam exhausting system to keep expansion chamber pressure stable, Also reduce the steam consumption;

3. Temperature control: Adopts temperature sensor to keep accurate expansion temperature, which is suitable for high density expansion, less broken beads;

4. Adopts PLC and Touch screen, electronic parts, valves are famous brand, which make the whole working procedure automatically and stable
