Adhesive.org Article Details How Adhesives Overcome Disadvantages of Mechanical and Thermal Fastening

Posted By ASC, Wednesday, July 12, 2017

Before modern adhesive technologists came up with advanced adhesives, engineers chose one of two methods: mechanical or thermal fastening. Today’s market demands, advanced materials and complex manufacturing requirements demand much more from manufacturers however.


The adhesive industry has responded with innovative and highly effective methods to meet these increasing demands and complexities, while addressing some of the inadequacies of traditional fastening methods.


Let’s look at some of the disadvantages of mechanical fasteners:

  • They add weight
  • They usually require holes that weaken components
  • They leave very visible bond lines
  • They carry all load at specific points, contributing to fatigue
  • They do not separate dissimilar materials and that can cause corrosion
  • Thermal fastening offers an alternative, but also has its disadvantages:
  • The substrates must be thick enough
  • They’re hard to disassemble, rework or repair
  • The aesthetics aren’t perfect
  • They require skilled labor and can pose a hazard to workers

 

Combining adhesives and tapes with mechanical and thermal fastening methods or utilizing adhesives alone gives engineers a smorgasbord of options for attaching materials to one another while overcoming difficulties and adding key benefits:

  • Adhesives and tapes allow for faster assembly
  • They can be stronger than welds
  • They are more flexible
  • They bond and seal at the same time
  • More...
