Abstract

See full text

The present invention relates to a hot runner probe having a shell-shaped probe body having a molten resin flowing surface which is combined to form a single unit with a ceramic heater wherein the ceramic heater is covered by the heater pattern that consists of high electric-resistance metal and has made the temperature gradient at the tip part higher than that at the center part, and then is insulation-baked. The present invention also relates to high-accuracy injection molding using the hot runner probe under the proper and ideal temperature distribution, by applying the ceramic heater, which is provided with temperature gradients, to the increase and decrease of resistance values due to temperature changes by the one circuit control means.
