INSERT MOLDING

What is insert molding?

Insert molding is an injection molding process whereby plastic is injected into a cavity and around an insert piece placed into the same cavity just prior to molding, thus the term insert molding.

The result of insert molding is a single piece with the insert encapsulated by the plastic. The insert can be made of metal or another plastic. Insert molding was initially developed to place threaded inserts in molded parts and to encapsulate the wire-plug connection on electrical cords. Insert molding is also used quite extensively in the manufacture of medical devices. Typical applications of insert molding include
insert-molded needle hubs and luer fittings and bifurcations, as well as encapsulated electrical components and threaded fasteners. There are few design limitations or restrictions on material combinations.

In the simplest sense, we use insert molding to provide more options with plastic in our injection molding process. If we place an insert into the mold, the plastic can fill the space around the mold. Another option is to inject the plastic inside the insert.

To imagine how commercial plastics are applied, picture in your mind a common household object – the orange extension cord. This is more versatile piece of electrical equipment you bring out of the garage once a year to arrange the outdoor Christmas lights. The plastic coating around the wires of the electrical extension cord insulate the wires to prevent fire.

With plastic molding technology, wires are made safe. You get the option to stretch your extension cord almost anywhere until you run out of cord.
It sounds really simple because we have invested considerable sums through the years of building our business to make plastics efficiently and cost-effectively.
