Various processes provide broad application Hirai Seimitsu Kogyo installed carbon dioxide gas(CO2) laser machines and wire-electrical discharge machines (Wire EDM) which enable us to cut or to make through holes on the metals, plastics and ceramics which can not be processed by etching method. In addition, they can provide widespread application by combining etching process with carbon dioxide gas laser cutting or wire-electrical discharge cutting process. Reworking process on the finished products are also available.

	We can meet various requests by adding stamping process on previously etched products.			It is possible to laminate various metal products (e.g. metal masks) by spot welding method.Ｗe can meet various demands by combining etching and spot welding with additional processes such as reaming, tapping or drilling process.

	Several metals can be metallurgically bonded by atomic bonding force on the metal surface when they are heated and compressed. There are 2 ways, one is standard thermal pressure bonding in vacuum furnace, and the other is diffusion bonding which can bond metals on the molecular level in Vaccum Hot Press machine.
