Metal treatment
A laser creates microscopic 3D structures on the metal surface that help anchor the plastic. Other surface treatments are also possible.
What if metal and plastic could bond without adhesives? hyJOIN® heats the metal precisely, melting the plastic at the interface. As it cools under controlled force, a durable bond forms opening new possibilities for lightweight design
A laser creates microscopic 3D structures on the metal surface that help anchor the plastic. Other surface treatments are also possible.
Metal and plastic components are aligned and fixed together in a precision jig.
An induction coil heats the metal without contact. The plastic softens and is pressed into the microscopic surface structures.
As it cools, the plastic solidifies within the metal’s microstructures, creating a durable, media-tight bond. The materials can be separated for recycling.
Controlled heating and dedicated tooling allow the bond to be separated for repair or recycling, extending the product’s life cycle.
