Multi-Cavity Molds vs. Family Molds: Which Best Serves Your Needs?

A close-up picture of a multi-cavity plastic injection mold with four similar parts inside, meant to serve as a comparison between multi-cavity molds and family molds

The process of injection molding involves plastic being inserted into a hollow mold cavity. The finalized product takes on the shape of the desired part. However, what if your project requires multiple plastic parts? Designing and building several molds is expensive and time-consuming, which is where multi-cavity molds and family molds come into play. In this blog, we will discuss the difference between the two and how to determine the best option for your needs.

While the US-China trade war certainly presented a major disruption of imports, COVID-19 is putting a strain on the global economy that’s forcing many companies to rethink their sourcing strategies. These shifts in imported vs. domestic manufacturing have generated overarching implications for US-based industries. In particular, the injection molding industry has begun to witness companies favoring plastic parts produced locally over outsourced products. These changes are further explained in an annual analysis known as the Reshoring Index.
