Foam machines first appeared in foreign countries, the original models are used in high-speed rotary-round bubble, which by the foaming mechanism is taking a bubble, and then the bubble would of artificial cement mixed with slurry made of foam. This mechanism of foam the size of the bubble get uneven, large diameter bubble, the high rate of bleeding, as the artificial bubble out, and then joined the mixer, work efficiency and impact of automatic control. In recent years, automatic high-pressure foaming machine in our country has to be generalizable. This foam machine multiple of foam, foam uniform small bubble of high quality, high degree of automation and high efficiency.

Later, as technology advances off, the foam machine continuously improve the technology, the new models continue to emerge. In recent years, Chinas ongoing machines foam technology upgrade and transform and has developed into a foam, mixed and pumped into the automation equipment.
