Multi cavity mouldis an injection mold that has more than one cavity. The shape of each cavity is the same. Multi cavity mold designis 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 molddesign will help to make high-efficiency production.

Sometimes we will mix up the meaning of multi cavity moldand 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.

With the rapid development of mold making,Packson moldalso makes the multi cavity mould for meeting the demands of customers. Especially for a medical industry like BD, they have the need for multi cavity soft plastic moldproduction. Such as disposable products: injection syringe, testing tube, and container.

Why Choose Multi Cavity Mould?

The Benefits of Multi Cavity Injection Molding


Multi cavity mould can be more than one cavity of the part with the same shape. Multi cavity injection molding is able to produce a large number of parts per molding cycle. It's suitable for high-volume production. Here are some other benefits of multi cavity injection mold:

Quick Lead Time: The cycle time of lead time will be shorter since numerous parts can be done per cycle.

Competitive Mold Cost: The cost of a mold with 2 cavities is cheaper and we will cost less than making 2 separate molds.

Low Part Price: Multi cavity mould helps reduce the part price by shorter labor and machine time.

Order Flexibility: It’s difficult to meet a demand for a million parts only by mold with a single cavity. Multi cavity moulds enable you to place large production orders that can be accomplished with high efficiency.

A Single Mold VS Multi Cavity Mold


A single cavity mold will create a single cycle while a multi cavity mold can make more than one product per cycle.

However, it's up to the customer's actual situation no matter they choose single or multi cavity mould. When customers require millions of the same parts with a short lead time and low part cost, a multi cavity mould is a good choice for them to get parts into the market quickly and competitively. But multi cavity moulds are not the best solution for all the projects since it requires more investment than single-cavity mold. Multi cavity mould needs substantial investment during or before project processing. Therefore we need to choose a suitable multi cavity mould solution according to the project property.
