The mechanical connection option
The transportation industry often prefers elastic bonds over mechanical fasteners. Yet, in some instances it is better to opt for mechanical fasteners. For example when the vehicle’s production process involves extremely high temperatures. The use of adhesives is often limited when higher temperatures are involved. Yet, elastic bonds combined with a powder coating process still continue to be an option.
When there is no time for curing the adhesive, a mechanical or hybrid bond may also be preferred. Adhesives require time for curing and building up their strength as a result of which the bonded materials temporarily need to be fixated. Furthermore, the bonding process is irreversible. After the adhesive has cured, the materials cannot easily be disassembled, nor can they be easily disassembled in the case of welding, while disassembly is possible when bolts are used.
