PSG Plastic Services
On January 1, 1962, the entrepreneurs August Fuchslocher and Richard Rohlf founded PSG in Mannheim for the targeted marketing of their extremely successful products.
The original products were the Fuchslocher-Shut-off Nozzle and the Rohlf Temperature Controller. These two developments set directional milestones in the at the time still very young branch of plastic processing.
The successful marketing of the two original products led to an intimate knowledge of the requirements of the market, and further product ideas. From this came an expansion of the product range and a continuous growth of the once small business to a middle-sized company group with three production locations.
Further information about the development of the individual product areas can be found under each product in the navigation menu.
PSG Hotrunner Systems
The area of Hotrunner Technique bears the mark of our many years of experience and has a very wide range of products with which we can serve applications in the most varied of branches individually.
We developed our first standardized Hot Runner nozzles in 1973. Using the latest in technology of that time, they were heated internally using the high performance cartridge heater FIRERODŽ with an integrated thermocouple. In striving towards an optimization of the rheology, we developed an advanced heating process, and in 1979 the externally heated series Thermoject II of nozzles was brought to production readiness. At that time, small nozzles especially still needed to be heated with low voltage (Thermoject III).
The first standardized large nozzles were the Thermoject IV series, added to the product line in 1986. (German Patent G86 18 162.9) The current program includes production series nozzles from Micro to Maxi. The system solutions range from nozzles with manifolds through ready-to-connect systems up to "Hot Halfes".
Machine nozzles (the Fuchslocher Shut-off Nozzle) and filter nozzles compliment the program as important components for the plastic melt on the way to the cavity.
