moulding

The changes that the foetal skull—which has a rigid face and base and a mobile cranial vault—undergoes to enable it to exit through the birth canal.

moulding

A process for making a lens in which a hot piece of glass (called a parison or gob) or liquid polymer (for contact lenses) is pressed to a predetermined shape. Frames can also be manufactured by pouring a soft material (plastic or molten metal) into a mould which takes on the desired shape after cooling (or drying). The technique is useful for large volume production. Note: also spelt molding. See spin-cast contact lens; surfacing.

Clamp-tonnage predictions are also enhanced by using pvT/compressibility material data to simulate the common molding practice of stopping the ram before the cavity is completely filled, allowing the compressed melt to expand into the remaining area.
