After reaching the working temperature, which is between the transition temperature and the softening point of the glass, the moulds close further and start pressing ...

Once the final layers of fiberglass are applied to the mold, the resin is allowed to set up and cure. Wedges are then driven between the plug and the mold in order to ...
