ABSTRACT:
Flowable thermosetting synthetic-resin material is fed to a plurality of pressurizable buffer compartments and then to a plurality of respective molds having differently dimensioned mold cavities. Each of these compartments is pressurized so as to maintain pressure on the molten material in the respective molds during the molding and curing operation, during which time the pumps that feed the material to the compartments may be stopped. Each of the buffer compartments has sensing means which operate the pumps of the system.
