• Compression Moulding: Compression moulding involves placing a pre-measured amount of material into a heated mould cavity and then
compressing it using a hydraulic press. The material cures and hardens as it cools.
• Blow Moulding: Blow moulding is used to create hollow objects, such as bottles or containers. A heated plastic tube is inflated inside a mould
to take on the mould’s shape.
Transfer Moulding: Transfer moulding is similar to compression moulding, but the material is forced into the mould through channels or sprues
using a plunger.
Casting and moulding offer several advantages:
• They can produce complex shapes that may be difficult to achieve using other methods.
• They are cost-effective for producing large quantities of parts.
• The processes can be used with a wide range of materials, including metals, plastics, rubber, ceramics, and composites.
However, these processes also have limitations:
• Certain materials may have limitations in terms of achievable detail or mechanical properties.
• Tooling and setup costs can be high, particularly for intricate moulds.
• Post-processing and finishing may be required to achieve the desired final product.
Both casting and moulding play essential roles in modern manufacturing, enabling the production of diverse products across industries. The choice
between casting and moulding depends on factors such as material, part complexity, desired quantity, and required properties of the final product.
