Gas Assist Injection Technology

Bauer has manufactured high pressure compressors for more than 60 years, and has earned the reputation as an industry leader in quality, innovation and reliability. With manufacturing facilities in Germany, France, England, Italy and the United States, Bauer brings its worldwide experience to your specific projects. Bauer was the first to manufacture turnkey systems for the gas assist Moulders. Bauer Gas Assist Systems are offered in various sizes and designs for adapting a single injection moulding machine to gas assist or to incorporate the entire plant. By combining a centrally located Nitrogen Generator (SNG) with remote Nitrogen Control Units (NCU), a coordinated plant wide system can be designed with the flexibility to use gas assist on any press at any time.
