Isopress AG


The Isopress AG located at Birmensdorf, Zürich was one of the first Thermosetting polymer processors in Switzerland.
Injection moulding plant

History

Isopress AG was founded 1940 and until 2015 it was located at Stallikonerstrasse 69, in 8903 Birmensdorf, in a former spinning building of the textile industry.
Until its dend, Isopress produced a wide range of thermoplastic and thermoset components. In particular, components for railway technology as well as lift buttons, filters for medical technology, electrical components for the Schurter Holding and knurled screws etc. The Isopress trained its own apprentices as plastic technologists, it also enabled plastic technologists apprentices of Lego Produktion AG Switzerland to study the second subject of thermosetting processing and to complete the occupational test in this field at the Isopress AG. In 2001, Isopress entered into a collaboration with Lanker AG in Oberriet. In 2015, Isopress AG was dissolved and integrated into Lanker AG.

Processing

The products were produced in thermoset presses, with and without inserts, in injection molding, in thermoset injection molding, and in thermoplastic injection molding. For this purpose, Sheet Molding Compounds were pressed in the thermosetting area as well as a kneading-type thermosetting resin with long glass fibers.
Thermoplastics: Acrylonitrile-Butadiene-Styrene, Polyoxymethylene, Polystyrol, Polycarbonate, Polyethylene, Polypropylene. In the thermosetting range: phenol-formaldehyde resin, melamine-formaldehyde resin, urea-formaldehyde resin, unsaturated polyester resins, phenolic resins, epoxy resin..
