It is a plastic injection molding process that combines plastic and other material. The insert, the inner part of an over-molded component, is inserted into the mold before injecting the plastic material. The mold is made from hardened steel to withstand the pressure and heat of the insert molding process. The Insert molding process is used for high and medium-volume production due to the high cost of mold fabrication.

Insert molding is used to add the insert, such as:

   • A threaded insert, a metallic part similar to a nut to add a rigid thread to a plastic part
   • Electrical pins and connectors
   • Screws
   • Keys
   • Gears

Insert molding offers many advantages:

• A rigid connection: The injected plastic englobes the insert, which results in a rigid connection between materials.
• Accuracy: Insert molding offers tight tolerances, around ±0.05mm.
• More rigid threads: The inserts are added to a plastic part to avoid wearing of threads in plastic material.
• Diversity of materials and colors: Many materials can be used to make Insert molding and a large selection of colors.
• No finishing is required: There is no need for post-molding operations as the molded parts come off the mold and can have a mirror glass surface, mat color, or texture.
• Low production costs: The production cost is reduced since post-machining operations are reduced or eliminated.

But there are some disadvantages as well:

   - Complex tooling design
   - Long cycle time

Insert molding is made through four steps:

1. Plastification and adding inserts: The plastic granules are transferred from the hopper to the mold using a rotating screw and molted using heaters. Inserts are added before the injection manually for low to medium-volume production or automatically for high-volume production.

2. Injection: The screw will advance to increase pressure in the injection chamber to inject the molted plastic into the mold. The two cavities are maintained close until the plastic solidifies

3. Cooling: After injection, the molted plastic will be cooled down to become solid using a cooling circuit. The screw will hold its position to hold the pressure inside the mold.

4. Ejection: After the molted plastic solidifies using a cooling circuit, the Die is opened, and the part is ejected via ejector pins. The screws will retreat to prepare for the next injection.

Obtaining a fully functional part might require extra processing for features that can’t be made with the Injection molding process, such as taping. The designed part should follow Injection molding design guidelines.
