Abstract
A system is disclosed for micro-molding articles. The system melts and pre-pressurizes thermoplastic material to a first level, within a plasticizing barrel. The melt pressure of the thermoplastic material is manipulated to a second level, within a hot runner. The melt pressure of the thermoplastic material is manipulated to an ultra-cavity packing pressure within a valve gate nozzle.
