Exhaust from diesel engines is a major source of air pollution. Nitrogen oxides (NOx), particulate matter (PM) and other pollutants from diesel exhaust are known to impair human health, causing cancer, heart and lung damage, and impaired mental functioning.
An automatic transmission case is a complex casting that includes a sophisticated valve body with many channels and passages. These channels and passages must be precisely connected to ensure smooth, accurate shifting.
An autoinjector is a medical device designed to deliver a dose of a particular drug. The devices were designed to overcome the hesitation associated with self-administration of a needle-based drug delivery device.
At first glance, press-fit assembly would seem to be much simpler than, say, welding or installing threaded fasteners. However, there’s a lot more to the process than simply jamming one part into another part.
We tend to think of press fit assemblies as being relatively small. For example, a bushing for an automotive control arm assembly is typically less than 2 inches in diameter. But, much larger assemblies can also be accomplished with press fits, too.
Every process change made by a manufacturer brings with it one or more unique challenges. Consider, for example, the challenges involved when switching from manual or pneumatic presses to servo models for low-force-pressing applications.
