The patented Inject-EX TM System is an improved Injection Molding process that employs a non-reciprocating (stationary) helical plasticating screw housed within a heating/cooling cylinder that is coupled to a plunger head assembly, drive housing and motor that Conveys, Melts, Homogenizes and Injects molten polymeric material more precisely and efficiently, along One Axis, comprising a unitary Inject-EX TM Unit.
The Inject-EX TM 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 TM System’s unique Mechanical Design addresses these deficiencies and delivers a more precise shot.
