The TRI System is a single piece bonding technology for metal and resins which utilizes Toadenka's original nano thin film technologies.
This technology allows for metal and resins to be bonded into a single piece without adhesives by using a technology where a bonding film with high chemical reactivity to both metal and resins is formed in addition to insert molding technology.

In normal insert molding, it is necessary to process the shape of the metal which will serve as the bonding mechanism. In addition, the process also resulted in gaps in the bonded surfaces, making for poor seals.

In this technology, even bond is formed by manifesting the bonding mechanism on to the metal surface (chemical bonding) and a firm. This means there is no need to machine the bonding surfaces and allows for free design of the part shapes. In addition, this creates a bonding strength superior to that of adhesive intermolecular force bonding, which provides superior seals, pressure resistant water proofing, oil proofing and heat resistance.

These outstanding qualities allow for the technology to be used in vehicle mounted with lithium ion rechargeable battery seal port plate seals and it has been proven in use in HONDA FCX fuel cell automobile ultra-capacitor parts.
