Assembling one part to another usually requires a third material, screws, rivets, adhesive or filler metal, but it doesn't have to. In fact, sometimes all you have to do is bend, fold or deform a feature on one part to capture the other.

A press fit is an assembly in which one part is inserted tightly into a hole in another part. The inserted part is typically 0.001 to 0.002 inch larger than the mating hole. The assembly stays in place through friction and the force of the two parts pushing against each other.

Global automotive supplier IFA Group makes driveshafts and other components for cars, trucks, tractors and industrial machinery. The company has assembly plants in Germany, Poland, China and the United States.

Promess, Inc. has introduced a new servo-based electro-mechanical actuator intended for applications requiring programmable rapid non-stop motion at frequencies not well suited for ballscrew-type presses.

The Promess Platen Press is designed for assembly and material preparation applications in battery manufacturing, aerospace component production and similar areas requiring precise application of high force over a large area.
