Harburg-Freudenberger Maschinenbau GmbH
The company
Harburg-Freudenberger – New Methods of Compounding
Renewable sourced Raw Materials
Harburg-Freudenberger Maschinenbau GmbH is one of the world’s
leading mechanical engineering and service companies in the field of
rubber and polymer mixing technology, tire technology and edible oil
technology. Around 1,200 employees at the production sites Hamburg-
Harburg, Freudenberg, Belisce (Croatia), Akron and Topeka (both USA)
as well as a world-wide comprehensive network of service stations and
numerous agencies abroad emphasize the international orientation of
the company and ensure a global presence.
The polymer mixing division is traditionally located in Freudenberg.
Since 1956, then still under the name of Werner & Pfleiderer, heavy
duty internal mixers are the core of the range of production. Following
the increasing interest of the industry in Wood Plastic Composites
(WPC) and Natural Fibre Plastics (NF-P), in recent years Harburg-Freudenberger
developed innovative processing concepts being tailored to
the special demands of these materials and implemented the concepts
successfully with regard to mechanical engineering. Complete processing
lines – from material handling systems to ready packed granulate –
belong to today’s product offering. Depending on the size of the customer’s
plant and requirements, throughputs of more than 3,000 kg/h
are possible.
