Single Cavity vs Multi Cavity Mold

In injection molding projects, the number of mold cavities determines its structure and characteristics.

Initially, single-cavity molds were commonly used for small batch production of single products.

However, as market competition intensifies and consumer demand diversifies, a single production model becomes insufficient.

Multi cavity mold, with multiple cavities in a single mold, can produce multiple products simultaneously, significantly improving production efficiency and shortening production cycles, bringing substantial economic benefits to injection molding companies.

So, what are the differences between single cavity and multi cavity injection molds? How do you choose between them?

Next, we will delve into an in-depth discussion on the topic of single cavity vs multi cavity mold.

What Is Single Cavity Mold?

A single cavity mold is a mold structure designed for manufacturing individual parts, containing only one cavity. It is suitable for producing smaller quantities of parts.

This mold structure is relatively simple and has a lower cost, but its production efficiency is relatively low, making it ideal for situations where product diversity is high and production batches are small.

In the plastic processing industry, single cavity molds are also known as single parting surface injection molds.

They are one of the simplest and most basic forms of injection molds.
