Molding (process)

Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix.

[2] The liquid hardens or sets inside the mold, adopting its shape.

[3][4] Piece-molding uses a number of different molds, each creating a section of a complicated object.

Blow molding is a manufacturing process for forming and joining hollow plastic or glass parts.

A release agent is typically used to make removal of the hardened/set substance from the mold more easily effected.
