Family injection molding produces a set of various shaped components that are molded at the same time and are manufactured from the same material. Family injection molds can be run to produce parts in a set at the same time, individually or in groupings.
The advantage is the tooling cost decreases and part price is lower verses a single cavity tooling. However, family tools can be difficult due to the natural imbalance of material flow in the cavities.
We utilize mold fill simulation to learn how parts will fill in the mold which enables correction of potential problems in the design phrase before the injection mold is even manufactured. To help improve performance, reduce variation and improve balance during the injection molding process, Crescent utilizes sequential valve gating.
