A key procedure in the assembly of automobile transmissions at the Volkswagen plant in Cordoba, Argentina, involves piecing together the top and bottom pieces of the transmission. A robot applies a sealant that helps join the two pieces. Smeared or irregular sealant lines, or sealant falling into the bottom block can result in a defective product.
In the summer, high temperatures can cause the sealant to soften, resulting in gaps in the sealant or sealant material dripping into the transmission block. Even when using a machine to keep it cool, the robot does not always function correctly. An effective seal is crucial to avoid transmission fluid leaks.
