Patent abstract
Disclosed is a nozzle tip, having a tip insert attached to a nozzle tip outlet end of a nozzle tip body, the tip insert being made of a material, or having a thermal barrier coating, having a thermal conductivity value of K<10 W/m ° K, and having a lower thermal conductivity than that of the nozzle tip body, to preclude the conduction of excessive heat to the nozzle tip outlet end, and promoting a more decisive fracture of the solidified resin at a gate orifice upon ejection of a molded product, thereby eliminating a string of molten resin and a vestige of excessive height, both of which are undesirable, on the molded product.
