Plastic Insert Overmolding: The process by which small parts of virtually any substance are combined into a single component through the injection of plastic into a cavity and around an insert piece placed into the same cavity. Some common applications are:
- Metal bushings, levers, tubes, posts, threaded inserts, or studs
- Electronic devices; current distribution parts, RFID housing, light bulb / LED connector
- Medical devices; needle hubs, tube valves, rehab products • Keys with electronics within the head
- Tools; screwdrivers, wrenches, with soft grip handles
- Knobs for appliances, switches or mechanical parts
The above mentioned products are representative of example insert molded products but do not by any means represent our full capabilities.
Overmolding Materials: Plastic Insert Molding is similar to the other processes at Mountain Mold and Die, in that it can be done with a wide variety of materials including:
- polyethylene
- polypropylene
- polyvinyl chloride
- thermoplastic elastomers
Benefits: Plastic Insert Molding is most often used as an efficient means of replacing common assembly methods due to the following benefits:
- Reduced labor and assembly costs
- More reliability
- Reduced size and weight
- More design options
