For automotive exterior and interior components, meeting stringent surface quality standards can be challenging. Key considerations include proper gate placement and preventing defects such as air traps, weld lines, shrinkage and warpage.
These components are commonly made from engineering plastics reinforced with glass fibers. Major challenges include dimensional tolerances and warpage caused by fiber orientation.
Automotive lenses demand exceptional optical quality, requiring tight control over birefringence and weld lines. For lamp housings, thermosets are often used in the injection molding process, where uniform heating and molding conditions are crucial.
