Advantage of HOT RUNNER SYSTEM 1,Because product must be produced using 100% of new resin without any loss at all the time,defect or trouble due to foreign material can be prevented. 2,Filling up cavity is needed only, because resin is always being melted up to gate, thus the time of injection, measurement, cooling and frame opening/closing is shortened as well as the time to take out sprue and runner. 3,Improvement of product quality Because the inhection pressure ofinhection molder is directly transferred to cavity, the problem of product shrinkage, weld, and deformation due to internal stress can be solved. 4,Increase of mechanical efficiency Efficiency of molder is enhanced because injection quantity, pressure, mold opening distance may be decreased as much as the amount of sprue and runner. 5,Extension of mold life The pressure exerted on the mold is decreased due to decrease of injection pressure and 3-stage mold of large type may be converted into 2-stage mold in case of using Hot Runner System, so that the trouble which can occur in 3-stage mold may be prevented.
