Plastics 101 - Session 5

1:45 - 2:30 p.m.

This presentation will include a discussion of:

• resins for injection blow

• co-ex capabilities

• different screws available

• application container min and max sizes

• machine fundamentals and functions

a. injection system (inject profile / pack and hold
        / suck back)

b. injection nozzles and gates

c. manifold distribution design and limitation 

d. manifold heading vs. hot runner system

e. perform mold (nozzle sizes / adjustment to the
       extruder nozzle / heating or cooling mold zones

f. trigger bar function and operation

g. core rod (design to the perform cavity for
       proper weight and wall thickness distribution /
       core rod top and bottom blow when are they
       used / core rod opening gap function / core rod
       tip cooling when used / when is a cooled or
       heated core rod required)

h. calculation for perform mold pressure
      (tonnage required)

i. blow mold function (min and max blow out
       ratio / different cooling zones / base cup spring
       loaded function)

j. stripper bar and function

k. different options available for the injection
       blow process

l.      typical machine size and applications
