Trending in the Automotive Industry is the swap from mechanical fastenings to using adhesives. Here are 7 reasons why:
1) Adhesives are good for bonding dissimilar parts. Traditionally, mechanical fasteners such as bolts, rivets, screws, and welds were used to connect parts in car manufacturing. But all these mechanical fasteners pose a challenge when trying to connect items of different materials; like metal to glass or plastic to steel.
From an engineering standpoint, it is difficult to drill holes in metals, plastics, and glass. In addition, dissimilar parts expand at different rates due to heat and pressure. This causes stress on the bond and warping to the materials which could lead to problems and possible failure of the parts.
