The foaming machine is the core part of the continuous sandwich panel production line, which directly affects the quality of the production panel.

The foaming performance of the panels produced by Weihua's four-component PU foaming machine is quite good. 

It can produce refrigerated sandwich panels with a thickness of 250MM and a flame retardant grade of B2, with a high percentage of enclosed area and good inherent coefficient.

WEIHUA Machinery is the only Chinese company that won the bid for the United Nations pentane continuous foaming machine project. 

WEIHUA has mastered the technology of pentane storage, transportation, mixing and safety, and the technology has actually been put into production in 2014. 

It also provides customers with a full range of services, such as establishing a staff training mechanism, operating rules and regulations, and a post-leak warning mechanism to achieve absolute safety from machines to personnel.
