Through its determined commitment to the development of vacuum and extraction technology for the technically complex degassing of plastic melts, Busch has acquired the world’s largest pool of know how in this area. This know how made it possible for Busch to build dry, sealed vacuum pumps that are today’s industry standard. Busch vacuum systems for the degassing of melted plastic materials are built to match the specific extruder and material and are constructed so that they can be directly attached.
