Does any one know if a 22'x22'x2" part can be injection molded? Is such a size possible? Are there examples out there of large modeled parts?

A related process called "Resin Infusion Molding" or some such flackery has taken over production boatbuilding. In it, dry reinforcement is pre-placed, the hull mold cavity is closed, and thermoset resin is pumped in. The pressure is much lower than is common in thermoplastic molding, but the idea is pretty much the same. Its big virtue is that the smell, and the "organics" are contained, and not released for the EPA to sample.

Unless it had numerous screws and barrels, melt residence and injection time would be 10s of minutes.
Thick section foam moulding reduces these numbers a bit.
Last I heard, a company called RELN in Sydney Australia has the largest injection moulding machine in the world. They do rainwater tanks, I would estimate from memory at about 12 or 13 foot diameter.
I can get the actual numbers for shot size, clamp force and maximum projected area moulded to date if you like.
