Sequencing CoĆinjection
This chapter describes how you program the operation of screws A
and B for the following co-injection sequences:
•
A only, or B only
•
A and B
•
A then B (standard programming)
– inject all of A
– inject all of B
•
A then B (co-injection programming)
– suspend the start of B
– inject A to completion
– from some point in A, inject B to completion
•
ABA
– inject A to some point
– from some point in A, inject B to completion
– resume A to completion
You can reverse the role of A and B for another set of valid sequences.
We give you explanations with example bit/word values for various
combinations. You can achieve similar results in a variety of ways.
Co-injection parameters are not used. You set up for standard
injection where you inject a single material from a single head.
You determine which QI module will be used as the “master” to
control cycle operation. Only one module will transition to
pack/hold. In this example, we let QI(A) be master, so we disable
QI(B)’s automatic sequence into pack/hold (IPCB02/B08 = 1).

We programmed only one co-injection parameter.
Description: QI(A) setup QI(B) setup Co-inj. word/bit:
enable injection cycle suspension on start No No DYC03-BO4 = 0
disable automatic sequence into pack/hold No Yes IPCB02-B08 = 1
enable injection cycle suspension on screw position No No IPC02-B10 = 0
screw position (of other) to exit suspended injection No No IPC08 = zero
screw position to suspend own injection No No IPC56 = zero
Important: We identify addresses associated with QI(B) with the
letter B inserted as shown. For example,
IPCB02-B08.
