Chapter 7: Processing Thermoset, LSR and Ceramic Materials

Thermoset plastics are chemically setting synthetic resins. Thermoset plastics set in the hot mould by crosslinking (chemical process), as opposed to thermoplastic freezing in a sufficiently cold mould (physical process). Synthetic resins tend to form shrinkage cracks, since a plastic deformation is practically impossible.

Transfer molding of polymers

 · Web view

The mold, equipped with a heating system, provides . curing (cross-linking) of the polymer (if thermoset is processed). The mold is opened and the part is removed from it by means of the ejector pin. If thermosetting resin is molded, the mold may be open in hot state – cured thermosets maintain their shape and dimensions even in hot state.
