Week 8 - Challenge 6 - Core & Cavity Design

INJECTION MOLDING;
Generally, injection molding has two major components: the movable halve and fixed halve during injection molding process.

CORE AND CAVITY;

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.

PARTING SURFACE;
Design the injection mold structure as simple as possible. Avoid or reduce side as much as possible to reduce the complexity of mold making. Ensure appearance requirement of the molded parts. Flash or mismatch occur usually on parting surface should not be designed on any high quality requirement surfaces. Ensure adequate venting.

PARTING LINE;

The parting line of a die cast component represents where the two different sides of the mold come together. This line often (but not always) marks the border between the inside and outside of the part. The location of the parting line indicates which side of the die is the cover and which is considered the ejector.
