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.
DANIELSON, CT—Spirol International Corp., a leading producer of coiled spring pins, slotted spring pins, disc springs, inserts, shims and other fastening components, has received the 2020 General Motors Supplier Quality Excellence Award.
When a press application requires 1,000 pounds of force or less, manufacturers increasingly prefer an electromechanical servo press to a manual or pneumatic one.
Evolution is inherent to the materials and equipment used in assembly, regardless of the product being made. For example, semi- and tank trailers increasingly feature composite-material components, along with those made of traditional steel or aluminum.
In the classic game Pin the Tail on the Donkey, players use a push pin to attach the tail to the donkey. On a metal or plastic toy donkey, however, a push pin would be unable to hold the tail in place, especially if it needs to move in some way. A better choice for this application is a solid metal dowel pin.
Diabetes is on the rise worldwide. Some 10 million people are diagnosed with the disease every year. That unfortunate statistic has led to increased demand for insulin pens. These medical devices are used by diabetics to inject insulin.
