Multi Cavity Mold

Premium Rapid&Mold produces high precision single cavity injection mould and multi cavity injection mold for a wide range of components, including caps, straight connectors, syringe barrels, with or without tear-off caps, etc. The multi cavity mold such as 2, 4, 8 cavity mold, has more than one cavity of the same part because of the shorter lead time per batch, using a multi cavity mold can have a faster completion of the requested number of components.

The Advantage of Multi Cavity Mold.

  • More products can be produced by the same mold within the shot guarantee.

  • In most cases, a six split cavity mould has a lower total cost than four or six single-cavity molds

  • The requested number of components will be finished faster due to the shorter lead time per batch.

  • More efficient use of the cycle time

  • The processes of multi cavity mould are more stable

  • flow balance of cavity injection molding

  • Products price will be lower

How Can Your Project Benefit From The Multi Cavity Mold?

The multi cavity mold has more than one cavity of the same part, which can have over 64 cavities. The multi cavity mould is designed to produce multiple numbers of the same part in the same process and the same time.


The multi cavity mold is suitable for you if more than tens of thousands of parts per month are needed. When the customer wants to meet a certain price point, the multiple cavity mold will be a good choice. The capacity limitation will force you to buy a multi cavity mold. When you use multiple cavities injection mold, will know that your investment in injection molds & mold design is rewarded with lower piece prices. It is a reward that sometimes customers will choose to purchase multi cavity molds even their capacity isn't reached. A multi-cavity mold could be 2-64 cavities.


You'll quickly find out that what you are really buying is machine time. So the less machine time it takes to mold your parts, the less your parts will cost. A multi cavity mold can grow to quite an investment as cavities are added. The sooner you make that investment, the sooner you can reap its long-term rewards.

The Comparison Between Multi and Single Cavity Injection Mould

multi_cavity_mould.jpg1. Multi cavity mould can be used for producing more than one piece while the single cavity injection mould is applied to just create one workpiece.


2. The parts are small and only large injection moulding machines are available. Under this circumstance, multi cavity tool is more efficient than single cavity mold.


3. Cavity balance injection moulding process needs each cavity in a state of force balance on the whole, otherwise it is easy to cause abnormal wear of injection molding machine. But single cavity mold is unnecessary to keep balance.


4. The manufacturing of a split cavity mould is more complicated than that of a single cavity mold.


5. Multi cavity mould can be divided into 2 cavity mold, 4cavity mold and 8 cavity mold whereas the type of single cavity mold is less.
