Family Mold
Family molds are often utilized when two or more part designs are similar but not identical, or if mold cost is a driving factor. Two different parts can be produced from a single mold. This can save on time and expenses by sharing common mold components such as the mold base, but also allows for a single mold setup.
However, family molds are typically better suited for lower volume applications, and automation may be necessary to separate pieces during or after production. They also have the potential for greater downtime as repairs and modifications to a single part affect all the components within the mold. Some of the benefits of a family mold are lost if the parts in the mold are run in different resins.
Still, with today's cost conscious buyers and the desire for versatility family molds are becoming an increasingly popular design option.
