Hi-Rel Plastics provides heat insertion and heat staking services for securely joining plastic components and integrating metal hardware into thermoplastic parts. These processes support durable, repeatable assembly solutions for industrial, consumer, electronic, and specialty applications.
Heat insertion is a process used to permanently embed metal inserts, such as threaded fasteners, into thermoplastic components using controlled heat, pressure, and timing. As the insert reaches the material’s melt temperature, it is pressed into the plastic to create a strong mechanical bond with excellent pull-out and torque resistance.
Heat staking uses controlled heat and pressure to reform plastic studs or protrusions over a mating component, mechanically locking parts together without additional fasteners or adhesives. This process is commonly used for attaching plastic-to-plastic or plastic-to-metal assemblies, including electronic components, brackets, housings, and other precision assemblies.
Hi-Rel Plastics utilizes controlled processing methods to help ensure strong assembly performance, repeatability, and clean finished results across a wide range of product applications.
Hi-Rel Plastics offers heat insertion and heat staking services to securely install inserts or join plastic components using controlled heat and pressure. This process provides strong, reliable bonds while maintaining the integrity of the surrounding material.
