ABSTRACT:
The injection machine according to the present invention has an infrared ray heater disposed outside a transparent glass tube cylinder a reflector disposed outside the infrared ray heater, an injection cylinder to which the glass tube cylinder is coupled by way of a changeover valve, a transfer mechanism to transfer the resin material from the glass tube cylinder into the injection cylinder, and an injection plunger in the injection cylinder to inject the molten resin. Since an infrared ray heater is used for the purpose of melting the resin material, a desired temperature can be achieved in a few minutes, and the forming may be started in a short time.
