What is the difference Insert Molding vs Overmolding

When it comes to multiple manufacturing technologies, there are two main types of molding: insert molding and over-molding. Overmolding vs Insert Molding The general concepts of overmolding and insert molding are similar, but there are significant differences between the two processes. Insert moulding is often used to add metal features to plastic parts. In insert molding, the metal insert is placed directly into the injection the mold and then injected, giving the desired product in one shot. Overmolding process requires at least two injections to obtain the desired product. First, a plastic part is produced using plastic injection molding process, and then after it cools naturally, it is placed in another mold cavity and injection molded again, allowing the secondary plastic parts to be wrapped together.
