Ordinarily, if you want to join metal and plastic items together, you have to use either adhesives or rivets. Engineers at Germany’s Fraunhofer Institute for Material and Beam Technology, however, have developed a bonding “gun” that they claim makes for a much faster and cheaper joining process.
One of the problems with adhesives is the fact that the joined items have to be left alone while the adhesive sets, delaying further steps in the production process. Riveting, on the other hand, can damage plastic objects. Additionally, using either approach, manufacturers have to continually pay for more adhesives or rivets.
The Fraunhofer device gets around these problems, utilizing what is known as the HeatPressCool-Integrative (HPCI) process.
