Abstract
Low profile SMC is extensively used for high gloss, painted exterior automobile parts. In this application there are many secondary operations. First, there is inspection and scrapping of a normally few percent of blistered, cracked, and nonfilled moldings. Next, there is deflashing, punching, studding, and occasionally grit blasting and adhesive bonding of subassemblies. Then, parts with imperfect surfaces pass through a filling, sanding, painting, and inspection repair line until appearance is acceptable. Finally, parts are shipped to customers for top-finishing and further assembly.Keywords
