Thermosetting polymers are special polymers that once produced cannot be remelted without undergoing complete and final chemical degradation. Thermoset materials are processed to arrive at a finished product in two stages: in the first stage polymer chains are created, while in the next stage of molding-which is represented by heating or a catalyzed chemical reaction-the polymer chains are made to cross-link.
The techniques that can be used for molding thermoset polymers within the Ansa Composites plants are:
– Compression molding: carried out by subjecting the still uncrosslinked polymer to compression and heating.
– Injection molding: unlike the injection molding process for thermoplastic polymers, injection molding for thermosetting materials is done by heating.
For more than fifty years, the Ansa Composites Group has been involved in molding and stamping thermoset materials for many Italian and international industries; on the strength of this experience, metalreplacement (replacement of metals with technopolymer components), mold design and stamping of critical parts are offered.
