On the 18th, the cold-water amber of lithium bromide unit in the synthesis workshop of Henan Coal Chemical Industry Group Anhua Company was integrated into the high-pressure cold agglomerate of ammonia. Each operation index was normal, and the unit was successfully put into operation once. The unit can effectively reduce the gas temperature of the high-pressure water-cooled discharge outlet and increase the output of synthetic ammonia.

Lithium bromide is one of the key technical transformation projects of Anhua Company in 2010. During the trial operation for more than three months, the temperature of the gas at the high pressure water-cooled discharge port has dropped significantly, the system pressure and ammonia content have decreased, and the ammonia production and the amount of compressor air flow have been reduced. Significantly improved, the power consumption is greatly reduced.

Vacuum Forming Large Parts

Yiyongli is a leading supplier of custom plastic large part by vacuum forming process across a variety of industries.We can provide product design and manufacturing engineering assistance and is ISO 9001:2015 registered.


Vacuum forming is a very economical method for producing large plastic parts.It offers lower cost tooling and quicker prototyping than other technology. Vacuum forming is best choice compared to other manufacturing methods such as complex fabricated sheet metal or fiberglass, in large, complex shapes which require a lot of metal fabrication, grinding and finishing. Vacuum forming also compares favorably to injection mould in big plastic parts when small quantities.


Vacuum forming large parts are single component parts that come out of the actual product or a substantial part of the finished product. Usually they are enclosures or housings for equipment.Applications of vacuum forming large parts are seen in many industries, including medical equipment panels ,machine enclosures, engine covers for aerospace, transportation or construction industries, and rail-car interior trim or seat components.
