COMPRESSION MOLDING SYSTEM

摘要

To detect, by using an inexpensive device, a molten resin mass that is defectively handed from a molten resin mass conveyer device over to the metal mold and to enable the production to be quickly resumed after the apparatus has been halted eliminating the waste of the material. In handing the molten resin masses from a molten resin mass-feeding device 3 over to the female molds 20 of a compression-forming machine 4, an infrared thermometer 13 detects the molten resin masses that are defectively handed over by measuring the temperature of a portion of the female mold 20 on the outer side of an allowable range in which the molten resin masses are fed to the female molds 20. The temperature is high if the molten resin mass is present and is low if it is not present. Therefore, a defectively handed-over position can be detected relying on the molten resin mass that is decided to be present at the above portion.
