• The fabrication is the process in which the prepared resins in the form of granules or powder are converted into desired shape by using various machines or moulds.
• There are many ways by which the comounds materials are transformed into finished articles.​

Principle of moulding (Fabrication)

• The basic principle in this is partial melting (softening) of resinous mass by heating.
• These softened resins are further compressed in moulds with the help of high pressure to get the desired shape.
• In the case of thermosetting plastics moulded hot plastics is ultimately solidified through further polymerisation , called curing or setting stage while it is still in the mould
• In the case of thermo softening plastic, the moulded plastic material is further cooled or chilled for solidification of article.

Different methods of fabrication/moulding​

1. Compression moulding : suitable for thermosets
2. Injection moulding : suitable for thermoplasts
3. Transfer moulding : suitable for thermosets
4. Extrusion moulding : suitable for thermoplasts
