Under pressure?
It's one thing to manufacture a tube; it's another to test it to verify its characteristics. Regardless of the raw material or the production method used to make the tube, pressure testing can be a necessary step in verifying the tube's quality. Whether the tubing is used for structural...

Stamper, prototyper, assembler, or fabricator
Tooling build takes as little as a week. Quasar designs the tooling, keeps an extensive variety of raw materials in its inventory, and does all the machining. Outsourcing. Offshoring. Layoffs. Plant closings. Newspapers and business magazines are filled with stories on the decline of... Read more...

The problem with quality
The companywide scores, which represent the number of problems per 100 vehicles, are as follows: Considerable variation exists among individual divisions of some OEMs. At GM, for example, Cadillac's results prove to be the second best in the survey (103), while Hummer's are the lowest (225)....

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...

Getting it Straight
Before coiled material can pass through a die to produce an acceptable part, it must be straightened. Coil straightening is accomplished by bending a strip of material around sets of rollers that alternately stretch and compress the upper and lower surfaces so that the material's yield...

Improving perforating die performance
To perforate the part material, the material must fail. The harder the part material, the greater the forces on the punch and matrix become, resulting in sudden shock, excessive wear, high compressive loading, and fatigue-related failures. During impact and penetration, the cutting edges... Read more...

Merging research with manufacturing
It doesn't take vast financial resources, though, to gain access to modern research. By partnering with a university's engineering program, a manufacturer can benefit from the knowledge and experience of professors and students at a fraction of the cost of hiring researchers and... Read more...

Monitoring laser beam performance
In the last 20 years, the use of industrial lasers for cutting, drilling, welding, marking, and cladding has increased dramatically. Industrial lasers, unlike their laboratory cousins, are not designed with continuous monitoring in mind. The laser often is assumed to be operating at peak... Read more...
