Plastify

Mixer 4 may be any conventional single screw or twin-screw extruder equipped with heating means to plastify the thermoplastic resin mix therein.

At a soft initial deformation response, all cross-sections or loaded layers within the gauge length of the specimen may not plastify due to the variation of the actual load-bearing area along the specimen.

Some materials have a distinctly defined yield point, e.g. most steels, whereas other materials start to plastify gradually at very low stresses.

Oh. Well, I can't identify the spell that was cast – other than that it required a large amount of magic – which would fit in with a shrink and plastify.
