Week 8 - Challenge 5 - Core & Cavity Design

AIM-Create the Core and cavity blocks for the switch bezel designed in the earlier challenge.

THEORY-

CORE & CAVITY

The core is the male part which forms the internal shape of molding. The cavity is the female part which forms external shape of molding.

The core & cavity are the shaped sections in either half of the mould tool which give the plastic product its final shape. The hot molten material is injected into the core & cavity and then sets hard into shape. The design of the core & cavity is essential in the correct formation of the product.

CORE & CAVITY DESIGN FOR SWITCH BEZEL

PROCESS-

• OPEN component in catia v5
• parting surface create for component.
• with the help of parting surface upper part create core
• with help of parting surface lower part create cavity
