Injection molding apparatus for use in injection molding process, comprises (partially) transparent nozzle having nozzle body and nozzle channel, and radiant energy heater

摘要

An injection molding apparatus comprises (partially) transparent nozzle (22d) with nozzle body (24d) and nozzle channel, and radiant energy heater. The nozzle channel receives fluid material at inlet. The fluid material has a pressure induced flow causing the fluid material to flow along an axis of the nozzle channel from the inlet to an outlet. The radiant energy heater heats the nozzle channel to maintain the fluid material in a fluid state. An independent claim is included for heating a fluid flow in an injection molding process comprising receiving a pressure induced fluid flow in (partially) transparent nozzle having a nozzle body and a nozzle channel, such that the fluid flows along an axis of the nozzle channel from an inlet to an outlet; and using radiant energy to heat the nozzle channel to maintain the fluid material in a fluid state.
