Multi cavity mould is an injection mold that has more than one cavity. The shape of each cavity is the same. Multi cavity mold design is to produce multiples of the same part for high volume production since it means each production will produce a large number of finished parts. Multi cavity bait mold design will help to make high-efficiency production.

Sometimes we will mix up the meaning of multi cavity mould and family injection molds. But these two types of injection mold are totally different. Family injection mold also includes multiple cavities but the shape of cavities is quite different. In other words, family mold is suitable for making different parts by a single run. The family mold can be much harder to maintain during production because of the different shapes of the cavities. It also increases the risk of molding defects.
