Molded Metal Inserts
Molded metal insert fasteners are manufactured with a wide range of features including locking capabilities. Molded inserts are available in numerous varieties including blind and thru and are utilized when an insert is needed in a setting that is deeper than the insert's length to prevent material from seeping into the insert. Thru molded-in inserts are typically used in applications where the insert provides an attachment point in material no thicker than the length of the insert. Molded metal insert options include:
- Thru Thread
- Thread Blind
- Self-Locking Blind
- Bullet-Nose Type
Injection Molding InsertsInjection molding inserts are typically made from brass, steel or stainless steel and are manufactured with a threaded surface to provide better adhesion to the plastic. They are placed in the mold either by hand or by machine with the mold in a vertical position. This positioning allows gravity to keep the insert in place as the mold is closed. As the molten plastic resin is slowly poured into mold, it helps hold the insert in a fixed position.
Insert Molding combines metal and plastics, or multiple combinations of materials and components into a single unit. The process makes use of engineering plastics for improved wear resistance, tensile strength and weight reduction as well as using metallic materials for strength and conductivity.
Post Molded Metal InsertsPost molded metal fasteners provide certain advantages that mold-in inserts do not provide. Post mold inserts provide reduction of in place cost, no secondary operation to clean flash residue from threads, fewer rejects due to dislodged inserts and ease of installation.
