Abstract
Non-time dependent measured variables are used to effectively determine an optimal hold profile for an expanding crosslinking polymer part in a mold cavity. A system and/or approach may first inject molten expanding crosslinking polymer into a mold cavity, then measure at least one non-time dependent variable during an injection molding cycle. Next, the system and/or method commences a hold profile for the part, and upon completing the hold profile, the part is ejected from the mold cavity.
Claims11
A method for determining whether an expanding crosslinking polymer part is ready to be ejected from a mold cavity during an injection molding cycle, the method comprising:
- injecting molten expanding crosslinking polymer into a mold cavity;
- measuring at least one non-time dependent variable during the injection mold cycle;
- commencing a hold profile for the expanding crosslinking polymer part;
- and
- upon completing the hold profile, ejecting the part from the mold cavity.
