Multi-cavity Mold and Family Mold in Injection Molding

Injection molding is a manufacturing method used to mass-produce high-quality plastic parts. When we look at manufacturing service costs, we can see mold manufacturing on top of the list. That is why the right decision you will make in mold selection will be the most significant determinant that will save you from unnecessary costs. In this article, we’ll be taking a closer look at the difference between multi-cavity, and family molds, which allow mass manufacturing of more than one piece in one single mold.

Advantages of Using Multi-cavity Mold

Looking at the part and mold dimension, you can choose this mold if you can fit more than one product in a single mold. With multi-cavity injection molds:

Shorter Delivery Period: Orders are ready in less time because multiple parts can be produced per manufacturing cycle.
More manufacturing In Less Periods of Time: With a four-cavity mold, it’s possible to produce for times more at once. This allows for a faster manufacturing period.
Lower Part Price: Even though the cost of multi-cavity mold manufacturing increases, manufacturing times are shorter with molding, and much more can be produced in one go. This lowers the per part price.
Order Scalability: It is challenging to meet the demand for one million parts with single chamber molds. Multy-cavity molds allow you to demand large orders that can be completed on time, so they are ideal for companies with high volume manufacturing.

Advantages of Family Mold

Since the circuit, cooling period and pull ratio will be similar for different parts of equal dimensions that you will produce within the same order, you can produce these parts using a family mold. This way, you’ll eliminate the cost you would have in parts you would produce with different molds.

Easier Order: Ordering a product with more than one part can be complicated. You can catalyze your work with this type of mold, which contains the appropriate number of parts to complete your product.
Low Volume Order Potential: Family molds are cost-efficient for low volume orders since you don’t need to use different molds over multiple cycles to complete your product.
Efficiency in manufacturing: You can produce your parts in a much shorter period and make the manufacturing cycle more holistic and faster by using the family mold. The plastics used in injection molding are composed of the same material and have the same colour; the parts must have approximately the same dimension.

Family molds have some disadvantages compared to multi-cavity molds. The family mold has a higher defect rate due to the tooling complexity and multiple mold models in a single manufacturing cycle.

Conclusion

Multi-cavity molds and family molds share multiple similarities in the manufacturing cycle. Deciding which mold to use in your product depends on its model and complexity.
