We developed direct dry joining technology for metal to plastics. Usually joining of metal and plastics use adhesive bonding or bolt joint technique. In recently dissimilar joining unit by insert forming which done special surface treatment of metal which has micro structure on surface by etching process. But those case has much work to do like as wet process. We achieved direct joining metal and plastics which an innovative and simple methodology.
Our developed PMS process got much advantage for metal-plastics joining.
・Positive anchor effect
・Dry process
・Possible to big size joining
・Single process for metal surface treatment
・Possible to reduce pressure at joining process
・High speed process
・Without masking
・Possible to insert forming and unit joining
・Can use several joining technology like as laser , ultrasonic , hot press and more
PMS process only done at joining layer. Melting plastics by laser exposure penetrate to nano-micro structure of PMS layer on metal by positive anchor effect. It indicated laser joining process image as below.
Metal-plastics joining process
Our joining technology can do all dry process. And it can select methodology for your purpose.
For multi material joining
Our technology can joining to several aluminum alloy with thermoplastics like as PA and PP. It may use metal to CFRTP and more.
