With so many ways to formulate plastic to get just the right combination of color, texture, strength and durability, it’s easy to forget how the parts will be assembled. However, if the parts will be assembled with screws, overlooking such parameters as thread style, driver speed and boss design could spell disaster on the assembly line.
Additive manufacturing is no longer just for prototyping. More and more, the technology is being used to make production-ready parts. That's forcing engineers to begin thinking about joint designs and assembly processes.
Plastics and polymer composites are essential to a wide range of safety and performance parts in cars today. In fact, the use of plastic and polymer composites in light vehicles has increased from less than 20 pounds per vehicle in 1960 to 334 pounds per car in 2015.
