Spraying it right
For coil-fed applications, spray cabinets can be mounted to the feeder to accommodate passline changes. Most stampers understand the need for lubricants, but many apply as little as possible so they don't have to deal with the mess. Others take an opposite approach and flood the tool... 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...

Predicting the outcomes of laser thermal forming
Applying a laser or any other high-density heat source to the surface of a metal sheet for a short time will distort the metal. If this distortion could be predicted, the laser could be directed so that the sheet metal would form the desired shape. This idea opens up many possibilities,... Read more...
