A mold with more than one cavity cut into it to make multiple parts of the same material in one cycle is called a family mold. Typically, each of these cavities forms a different part number, which is ideal for prototype molds because of the fast molding cycles.

The family mold is a multi-cavity mold where each cavity creates different parts of the same product. The parts produced by each cavity may also be unrelated, belonging to the same product line or to the same project. Family Molds are great for manufacturing parts that are assembled together or maximizing the number of parts produced per operation.

Required Criteria for Our Family Mold Services

The family injection molding procedure has various benefits for the manufacturers and the customers. However, it also comes with some challenges and requirements that must be followed in order to get the best products to accomplish its application. Our expert team pays careful attention to all these requirements, including:

family mold

The Parts should be of the Same Material and Color

All parts produced through family molds must be the same material and color, as only one type of material can be injected into the mold at any given time.

Parts Will All Be Made in the Same Quantity

Every time the mold opens, the exact number of parts in the mold will come out. If the mold produces Side A and Side B to make one complete product, then each time the mold opens, it will produce enough parts to complete one product in every cycle.

Parts Must Have Similar Size and Volume

All cavities of the family mold are to be filled at the same time and rate. Having parts that vary in size and volume will cause issues with short shot and flash – cavities being underfilled or overfilled, respectively.

Materials Used for Family Molding

Here are the most commonly used materials for family molding:

Acetal Homopolymer/Delrin

PMMA (Acrylic, Plexiglas)


Material We Used

Finishing Option For Family Molded Parts

We offer multiple finishing options to complete the products made with the family mold process. You can choose from any of the following depending upon your application’s requirements:

high precision aluminium rubber and plastic automotive part manufacturing by casting and machining

Standard Finish

Interior, non-cosmetic finish according to the geometry of the mold.

SPI Finishes

Range of SPI finishes from Grade 3 diamond / high polish to 320 stone low polish. These Finishing options include SPI A-1, SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3.

Threaded Inserts

We can install the most commonly used and popular standard inserts in UNF and metric sizes.

As Molded

as the name suggests, the mold will remain ‘as it is’ – without any secondary texturing or polishing.

Mold Texturing

Creating textures on the molds so that it shows on the final product. This finishing option includes matte, swirls, patterns, and lines.

Laser Engraving

Engrave part numbers, designs, logos, or any other specified printing onto your parts.

Pad Printing

Application of an ink-based design to the surface.


Painting the surface with standard colors or Pantone matching, including Primer and topcoat. Masking available; EMI (copper) paint.

Industry Application & Tolerance

For our family molding services, we are typically able to maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be more than but not less than +/- 0.002 in. /in. (0.002mm/mm).

Family mold injection molding is a popular manufacturing procedure used across a wide range of industries to make sets of different parts that are similar or may fit together, like two halves of a single product. This process is ideal for:

Family Molding FAQs

Get key insights about Family Molding Services that could be crucial for your requirements.

What Is Family Molding?

Family molding is a type of injection molding manufacturing where part numbers join into one mold base simultaneously. The cavities for a few part numbers can appear on one section. This type of product manufacturing process involves making different parts for one product at a go through just one mold.

Are single-cavity injection mold, multi-cavity injection mold, and family mold the same?

No, these three molding procedures differ one from the another. A single-cavity injection mold is a mold capable of forming just a single product. If the mold manufactures more than one part at once in the melt, it is known as multi-cavity injection. The family mold refers to a certain multi-cavity mold for making many portions of the same commodity.

Are There Any Limitations to Family Molds?

On the other hand, casting molds are better for similar in size and material. It has been identified that such parts would be less efficient when they are either very large compared with others or made out of dissimilar materials since it may pose problems concerning quality control.

How Do You Ensure Quality in Family Molding?

To ensure compatibility of all parts in a family mold by matching material, size, and molding parameters we hold tight quality control. Each part is periodically inspected and tested to determine whether it complies with specified standards.

Can Family Molds Be Used for Complex Parts?

Family molds work best with simple parts. However, they are not suitable for simple parts since the quality of a single mold should match others where there is consistency with regard to the production process.

What Types of Products are Best Suited for Family Molding?

For example, moulding is ideal for family products like toys, electronic devices, and even medical equipment. This involves matching sizes, physical shape, materials as well as production process, which is best for same density metals.

How Do You Determine if a Family Mold is Right for My Project?

We evaluate factors such as the design of the components, materials compatibility, and custom manufacturing extent. If the elements may be correctly and efficaciously produced collectively with out compromising great, a family mold may be a appropriate option.

How do you ensure quality in your injection molded parts?

We appoint strict best control measures, inclusive of normal inspections and the use of advanced dimension tools, to make sure each component meets the specified specs.

What is the Typical Lead Time for Family Molding Projects?

Lead times can vary primarily based on the complexity of the mold and the production quantity. However, family molds typically reduce ordinary lead times due to their efficiency in producing multiple parts concurrently.

Can Family Molds Reduce Overall Production Costs?

Yes, family molds can extensively reduce production prices. By molding more than one components simultaneously, they keep on tooling fees, lessen cycle instances, and limit labor, main to ordinary price performance.

How Do Material Requirements Affect Family Molds?

All parts in a family mold must generally be constructed from the same material, as the mold is made for a specific plastic resin. This uniformity ensures consistent melting temperature and material behavior during the molding process.

Are Family Molds Suitable for High-Volume Production?

Family molds are particularly beneficial for high-volume production runs. They enable simultaneous production of multiple parts, increasing production and efficiency, especially for large orders of small and medium-sized parts.
