What is Insert Molding?
Insert molding is the process of molding a plastic part around different types of materials. Simple metal objects such as nuts or threaded rods are often inserted. However, insert molding can also be used to insert ceramic parts, other plastic parts, motors, threaded bushings, batteries, or warning labels into the molded part.
The process begins with placing the insert into the mold. The injection molds used in the insert molding process are machined to easily receive and secure the insert. Once the insert is placed, the mold is closed and the molding process can begin. As with regular injection molding, the mold is filled with molten plastic. After the plastic cools, the part is ejected from the mold. The inserted item is now firmly bound and integrated into the plastic part. There are many options for inserts that can be placed into the mold.
Benefits of Insert Molding
Plastic injection insert molding is an effective alternative to assemblies manufactured using soldering, adhesives or fasteners, with benefits including:
- Reduced assembly and labor costs
- Reduced size and weight
- Robotic automation in the insert molding process allows for fast and precise placement of inserts
- Improved component reliability
- Improved part strength and structure
- Enhanced design flexibility
- Consolidation of components
How Insert Molding Differs from Overmolding
Insert molding and overmolding are two completely different injection molding processes that both produce unique products. Overmolding is a process where one material is molded over another to create a product. The base material is molded first, and then additional plastic layers are molded around the base part. This creates a final plastic product.
Insert molding, however, is when the material to be inserted, usually metal, is injected into the mold cavity before the plastic is injected into the mold. The final product is a single piece with the metal insert encapsulated by the plastic. Plastic injection molded inserts can provide a fast and cost-effective assembly process, producing smaller and lighter parts.
Industry Application
From manufacturing functional prototypes to large volume production runs, insert molding is used across a wide range of industries for various applications, including:
Aerospace
Automotive
Medical
Consumer Products
Oil and Cas
