Molding is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a mold.
A mold or mould is a hollowed-out block that is filled with a liquid like plastic, glass metal, or ceramic raw materials. The liquid hardens or sets inside the mold, adopting its shape. A mold is the opposite of a cast (see casting). The manufacturer who makes the molds is called moldmaker or mouldmaker. A release agent is typically used to make removal of the hardened/set substance from the mould easier.
Types of molding include:
- Powder metallurgy and ceramics
- Compaction plus sintering
- Plastics
- Injection molding
- Compression molding
- Transfer molding
- Extrusion molding
- Blow molding
- Rotational molding
- Thermoforming
- Vacuum forming, a simplified version of thermoforming
- Reaction Injection Molding
- Laminating
- Expandable bead molding
- Foam molding
- Rotomolding
- Vacuum plug assist molding
- Pressure plug assist molding
- Matched mold
- Monkey Molding
