Overmolding, also known as injection molding or insert molding, is an important process employed in electronic connectors used in medical manufacturing.
Overmolding is a process where a single part is created using two or more different materials in combination. The first material (the substrate) is partially or fully covered by subsequent materials (overmold materials) during the manufacturing process. This unique injection molding process that results in a seamless combination of multiple materials into a single part or product. Overmolding allows the wire and connector to be combined, enhancing the assembly features. Similarly, molding over metal inserts creates an interface that provides value electrically and mechanically.
There are a number of benefits to overmolding when it comes to the electronic connectors used in healthcare device manufacturing. We’ll discuss some below.
