Family Mold Services

Certifications: IATF16949:2016 | ISO9001:2015

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:

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 Mold

Here are the most commonly used materials for family molding:

Acetal Homopolymer/Delrin

PMMA (Acrylic, Plexiglas)


Material We Used


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).


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

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:

Our Strengths

Market Leading

We never require a minimum order volume, and we use advanced quotation algorithms to get our clients reasonable pricing according to their budget.

What is Family Mold?

A family mold is an injection molding manufacturing process that combines different part numbers into the same mold base. There can be multiple cavities of the different part numbers. This production process allows the creation of different components of the same product in a single cycle using a single mold.

Benefits of Family Mold

Lower Tooling Cost

A family mold can be created with multiple cavities instead of creating multiple, single-cavity injection molds and paying the tooling cost for each one.

Lower Production Cost

Family molds help reduce production costs as the production time is lowered since there is no need to change molds for different parts. Consequently, the per-piece price of each part goes. 

Efficient Production

Using family molds when the production quantity is not very high in volume helps by manufacturing more than one part in one production cycle since two or more parts are produced in every shot.


Making a large volume of parts with a single cavity mold would take up the resources for weeks or even months. A family mold, on the other hand, can substantially reduce production costs and turnaround time while boosting scalability.


No, these three molding procedures are all different from each other. A mold that can only create one product at a time is a single-cavity injection mold. If a mold produces two or more plastic parts at a time, it is called multi-cavity injection. If a multi-cavity mold is used to produce multiple parts of the same product, then it is called a family mold.

Yes, Multi-cavity molds and family molds can generally be more expensive than a single cavity mold because of the extra machining required. However, as family molds produce multiple parts in a single go, they can be a lot more cost-efficient than single cavity molds.

Simply upload your product details and/or CAD files, and we will send you a free quotation within 48 hours or even less.

If your product has multiple parts to produce, then using the family mold manufacturing process may be the best solution for you as it offers many benefits, including:

  •  Low cost
  • Quick build
  • High quality
  • Mold frame sharing technology
  • Cost-efficiency
  • Diverse material options
  • Diverse surface finish options

There is no need to worry. You can just provide us with a description, and we can reverse engineer it to reach your product ourselves.

The molding produced by our family mold services has the highest quality standards and can be treated like end-use parts.
