Insert Molding

Engineering review within 72 Hours.
Night Owl Manufacturing provides insert molding services that integrate metal or secondary components directly into molded plastic parts during the injection molding process. Insert molding helps reduce assembly steps, improve part alignment and create stronger mechanical connections between materials.

Insert Injection Molding for Integrated Components

Insert molding is used when components such as metal inserts, threaded fasteners, electrical contacts or bushings need to be integrated into a plastic molded part. By molding plastic around the insert during the injection process, manufacturers can eliminate secondary assembly operations and improve part consistency. This approach is commonly used for parts that require durable mechanical connections or integrated hardware.

What Insert Molding Supports

Insert molding programs often support:
  • threaded metal inserts for fasteners
  • telectrical contacts within molded housings
  • reinforcement components for structural strength
  • bushings or mechanical hardware embedded in plastic parts
  • assemblies that would otherwise require multiple manufacturing steps
Insert molding simplifies production by combining multiple components into a single molded part.

Plastic and Metal Insert Molding

Insert molding can be used with a wide range of thermoplastics and insert materials. Common insert types include:
  • metal threaded inserts
  • brass or stainless steel components
  • electrical connectors
  • reinforcement pins or bushings
Many applications involve metal insert injection molding, where metal hardware is positioned within the mold before plastic is injected around it.
