Pairing the right hydraulic press with your application

October 11, 2005 | By Jay Douglas Hartzell

Choosing the right hydraulic press for your application is crucial. Identifying the right press capability up front can eliminate additional costs and startup delays. Four primary hydraulic press return capabilities are return on position, return on pressure, return on pressure with dwell capability, or combinations of the three. Shown is a press with return on pressure capabilities.

Blanking questions have you on the edge?

October 11, 2005 | By Young Seo

Reducing the damaging effects of fractures, burnishing, burrs, and rollover improves subsequent forming processes. The blanked edge condition can be improved by adjusting the punch and die clearance tolerance, shaving the area of the defected blanked edge, designing an appropriate contact profile of the tool and die, and understanding the mechanical properties of the sheet metal used.

Taking a look at automated spray control:

September 13, 2005 | By William J. Kohley

Spray systems often are regarded as simple on-off valve and regulation systems. In reality, though, spray nozzles are precision components designed to yield very specific performance under specific process conditions. Just because nozzles are spraying doesn't mean that they are spraying precisely, and precision spray performance makes a difference in throughput, quality, and bottom-line profits

Pressing through power failures:

September 13, 2005 | By John Meyer

When BMW Dingolfing (Germany) decided to modernize one of its transfer presses, the desired benefits included increased line availability, increased production through the use of an electronic transfer system, and reduced maintenance. However, one of its highest priorities was to minimize or eliminate the risk of production loss caused by interruptions to the power supply.
