1-6 Overview
The mode in which the module reads a feedback signal value and uses that
value to modify the output signal to achieve the desired result.
Those conditions that must be present (such as maximum time reached or
maximum position attained) at the time the module changes profiles or
makes the transition to the next profile.
The vacant area inside the mold that is filled with plastic to form or shape
the part. Molds can contain multiple cavities to make more than one part
per machine cycle.
A time value used to delay the start of the clamp open profile until the
molded part in the cavity has cooled and solidified sufficiently.
A clamp that has a hydraulic cylinder connected directly to the clamp
moving platen.
A mold that has heated passages to avoid forming a sprue between shots.
The mode in which the module performs open loop or fixed output manual
control instead of reading a feedback signal and adjusting the output signal
on that basis.
A mode of operation that allows the plasticate cycle to continue operating
during clamp open and part removal cycles.
PID, as used in this manual, refers to any closed loop control algorithm with
the following three tuning parameters: proportional, integral, and
derivative. Response of PID algorithms in the TurboPlastic module may be
somewhat different from the usual or normal PID algorithm, due to the
demanding performance requirements of many molding machines.
A passage in a mold that allows plastic to flow to the cavities.
The unwanted plastic that solidifies in the runners along with the part
being molded.
A clamp having a mechanical stiff-leg operator system which the hydraulic
cylinder moves to open and to close the clamp.
