Assembly Planbook - June 2008 - (Page 37) “Appliances are a logical application for adhesives,” he points out. “It allows you to hide lines and join large areas of flimsy material.” Fasteners Still Rule Archer says many engineers get nervous about strength. “When using adhesives, there is a fear of inconsistent results,” he explains. “In many cases, because there is such a wide variety of structural adhesive available, you need to think about it more than fasteners. Often, there must be an existing design problem that you want to overcome to justify adhesives.” In addition, Speth warns that stainless steel can cause problems for some adhesives, because of its ultrasmooth surface. “There aren’t many adhesives designed specifically for stainless steel,” he points out. “To get the best results, you may have to prime the surface, which can add time to the process. Epoxies would be my first choice, followed by urethanes. Acrylics are usually better for plastics.” Fasteners remain popular for steel applications such as hinges, electrical assemblies and main wall assembly.

And, they usually require fixturing and time to cure, which can limit their use on high-volume assembly lines. “Cure time depends on chemistry,” says Speth. “Epoxies can cure in minutes to hours, while urethanes set in seconds to hours. With UV-cured acrylics, it’s just a matter of seconds or minutes.” To overcome this challenge, most Kistler Process Sensing Separates Fact From Fiction and Good Parts From Bad ±600 με 0.01 Nm … 20,000 Nm 0.007 lbf-ft 14,750 lbf-ft 1 mN … 20 MN 0.0002 lbf 4.5 Mlbf detailed signature evaluations Kistler sensors for process monitoring of force and torque are synonymous with technological leadership in piezoelectric and piezoresistive measurement.
