What is a cavity in a mould

A cavity in a mold refers to the void space within a mold where the molten material is poured to create a specific shape or object. In other words, a mold cavity is the hollow area inside a mold that is designed to produce a specific product, such as a plastic bottle, a metal part, or a ceramic figurine.

When a mold is created, it consists of two halves - the core and the cavity. The cavity is the part of the mold that defines the shape and size of the final product, while the core creates any internal features, such as hollow areas, threads, or undercuts.

During the manufacturing process, molten material is injected or poured into the mold cavity, where it cools and solidifies to take on the shape of the cavity. Once the material has fully solidified, the mold is opened, and the finished product is removed from the cavity.

Cavity design is a critical aspect of mold design because it can affect the quality, functionality, and efficiency of the final product. Mold designers must carefully consider factors such as material properties, wall thickness, draft angles, and surface finish to create a cavity that can produce a high-quality product efficiently and effectively.
