About Insert Molding Process

As one process of injection molding, insert injection molding is the process of molding or forming plastic parts around other non-plastic parts or inserts. The inserted component is most commonly a simple object, such as a thread or rod, but in some cases, inserts can be as complex as a battery or motor.

Moreover, Insert molding combines metal and plastics or multiple combinations of materials and components into a single unit. The process uses engineering plastics for improved wear resistance, tensile strength and weight reduction, and using metallic materials for strength and conductivity.

Advantages of Insert Molding

A wide range of metal components can be used in the insert molding process, including screws, limiters, threaded fasteners, magnets, filtering screens, tubes, clips, mounting brackets, and more. These components can be stainless steel, brass, copper, aluminum, nickel, or bronze. Moxperts team will work with you to select the best combination of metal and plastic based on the part’s requirements.


It affords enhanced product design and manufacturing. The precision with which you can place inserts into a mold design cannot be achieved with other molding processes. In short, plastic parts with integrated components are much more robust and more reliable.

Light Weight

Plastic parts can be up to 50 percent lighter than their metal counterparts, which is one of the primary reasons many industries are turning to plastic molding for parts. From fuel efficiency to better ease-of-use for surgical instruments, lighter weight enhances performance and functionality.

Smaller in Size

The insert molding process allows the production of much smaller or thinner parts without sacrificing durability or performance. A simple example is vehicle components. Thinner door and console parts mean more room in the interior of the car.

Cost-saving Solution

Insert molding achieves cost savings in two ways. First, they allow the use of much cheaper materials.  Also, molding production processes themselves are cost-effective. Insert molding is a one-step process. Unlike other types of molding, assembly and labor costs can be streamlined.

High Efficiency

Insert molding eliminates a second assembly step in the manufacturing process. The insertion of metal or other components is integrated with the molding step, so there is no need for a stand-alone task. It saves time and money associated with labor and specialized equipment for these processes.

Variety of Materials

Insert molding can use many different types of plastic resins in the process—these include thermoplastics, which are eco-friendly since you can recycle them. The most common thermoplastics are polyethylene, polystyrene, and nylon. These are all lightweight, durable, and ideal for consumer products to heavy-duty industrial ones.
