Claim:
A process for making an injection molded part using a press, a cavity block, a moveable core block, a parting line defined at a junction between the cavity block and the moveable core block, at least one injection nozzle, a stationary inner insert and at least one spacer mechanism that is moveable relative to the core, wherein the cavity block and the moveable core block are moveable relative to the stationary inner insert, comprising: a) closing the parting line between the cavity block and the moveable core block; b) setting at least one spacer mechanism to a first shot position to locate the cavity block and the moveable core block to a first shot position relative to the stationary inner insert; c) closing the press to a first shot position; d) applying clamp tonnage to the press; e) injecting a first quantity of material to create a first portion of the injection molded part while keeping the parting line closed; f) releasing the clamp tonnage while keeping the parting line closed; g) opening the press to a predetermined position while keeping the parting line closed; h) setting at least one spacer mechanism to a second shot position to secure the cavity block and moveable core block in a second shot position relative to the stationary inner insert, while keeping the parting line closed; i) closing press to a second shot position while keeping the parting line closed; j) reapplying the clamp tonnage to the press while keeping the parting line closed; k) injecting a second quantity of material to create a second portion of the injection molded part while keeping the parting line close; and l) opening the press and the parting line and ejecting the completed injection molded part.
