This revolutionary new plasticating system was designed to ensure that each pellet is exposed to the exact same amount of energy during its journey from the hopper to the mold. The result is a melt that is more uniform and homogeneous than that produced by today’s conventional reciprocating screw systems. Not only does the Inject-EX™ produce greater quality melt, but it also delivers that melt in a more precise manner due to its compact, straightforward design that results in greater accuracy and control.

The Inject-EX™ addresses three major deficiencies of the reciprocating screw design; a. Viscosity variation in part caused by poor melt preparation and homogenization b. Variations in the quantity of melt dispensed due to poor/inconsistent closure of the NRV c. Continuous pressure changes across the shutoff plane due to melt decompression inconsistencies and viscosity changes due to heat input. Due to these variations the molding machine is not “smart“ enough to know when to trigger V.P. transfer positions or to determine the amount of mass that was displaced each shot without the use of expensive in-mold cavity sensors and additional processing power. The Inject-EX™ System’s unique mechanical design addresses these deficiencies and delivers a more precise shot.

Inject-EX™ plunger technology explanation. Polymer is conveyed, melted, homogenized, distributed and pumped downstream with the stationary Posi-Melt™ plasticating screw, through the patented plunger head displacing volume into the pressure vessel which forces the unitary Inject-Ex™ assembly to traverse in an upstream direction to a predefined position. The normally closed plunger head that is attached to the distal end of the barrel and is fit tightly with the pressure vessel is designed to open on pressure allowing the molten polymer to flow into the awaiting pressure vessel. By virtue of the kinetic energy of our springs that are a component of the plunger assembly, the poppet closes instantly upon screw stoppage. The precise instantaneous closure and tight diametrical fit with the pressure vessel allows the plunger head to act as a piston for precise mass displacement into the pressure vessel and subsequent distribution into the mold which occurs along ONE axis, eliminating the dead spots or temperature issues that are prevalent in the state of the art two component plunger systems. The technology is currently designed to process; 1. Thermoplastics 2. Thermoset LSR materials.

Inject-EX™ Systems can be retrofitted onto existing presses to turn old machines into “better than new”, be designed for molding machine OEMs who want to offer greater processing control to their customers., or bought as a full Injection Molding Machine through our collaboration with EdeX Technology Co., Ltd.
