The pressure is on
The 400-ton pressure testing setup shows the die components and bumper blocks. The traditional method of measuring pressure distribution in stamping operations—the die spotting blue technique—indicates the pressure points but not how much pressure. This makes it difficult to... Read more...

Setup or cover-up?
Even though we are in the age of CNC machinery, the old phrase "the tools make the bend" is as relevant today as ever. As tube bending applications have become more ex-treme, tooling design, setup, and maintenance have returned to a position of central importance. In rotary draw bending, four... Read more...

Dealing with internal pressure in free hydraulic bulging
Finite element analysis (FEA) is a numerical process that treats a single item, such as a metal tube, as a large number of small, individual components, or finite elements. It performs calculations on each of the elements and uses the result to predict the deformation behavior of the... Read more...

Mill coolant system design
Coolants are used to wash away oils, oxides, slivers, and dirt generated during the forming, welding, and sizing of tubes and roll-formed profiles. These coolants are a mixture of water and refined chemicals that help cleanse the process, protect part finish, extend tool life, and inhibit rust... Read more...

The basic elements of tubular hydroforming
Tube hydroforming has been well-known since the 1950s. However, with recent advancements in computer controls and high-pressure hydraulic systems, the process has become a viable method for mass production, especially with the use of internal pressures of up to 6,000 pounds per square inch...
