Mold Base vs. Mold Insert: What’s the Difference?

The primary difference between a mold base and a mold insert lies in their structural roles. A mold base is the standardized, heavy steel frame that holds the entire assembly and mounts to the injection machine. Conversely, a mold insert is a custom-machined internal block that fits inside the base to form the actual final […]

What is the difference between insert mold and over mold?

The main difference between an insert mold and an over mold lies in the base material and process sequence. Insert molding involves injecting plastic around a pre-placed non-plastic object, like a metal threaded nut. Overmolding, however, is a multi-step process that molds a secondary plastic or rubber layer directly over a previously molded plastic substrate. […]

How does insert molding work?

Insert molding works by placing a pre-formed component, typically made of metal, into a mold cavity before closing it. Molten plastic is then injected into the mold, encapsulating the insert. Once the plastic cools and solidifies, the mold opens, ejecting a single, integrated part with enhanced mechanical properties. 🎥 Watch the Process: See the exact […]
