Do your welds pass muster?

November 25, 2008

By:

For a job shop or manufacturer, maintaining weld quality begins with consistent shielding gas in the gas metal arc welding (GMAW) process. Consistently delivering the correct blend ensures proper arc characteristics and weld quality. Mixing technology, supply gas density, and gas usage patterns can affect the on-site gas blending system's ability to deliver a consistent blend.

Keeping consumables from consuming welding profits

January 15, 2008

Like every manufacturer these days, truck and trailer manufacturer Tico Manufacturing Inc. can't afford to waste any time on non-value-added activities. It recently switched its welders to Centerfire™ nonthreaded contact tips manufactured by Bernard®. These tips require replacement about once every two weeks; the previous tips were replaced three times a day. And because they are unthreaded, the tips take much less time to replace.

Programmable lubricant application accelerates stamper's die changes

October 9, 2007

Red Rock Stamping, Chandler, AZ, airbag and seatbelt components manufacturer, looked for ways to improve its die change processes to handle the anticipated business volume increases. A lot of cleanup had been required around the machines as a result of the lubrication system. By installing a new fluid application system by UNIST, the stamper gained more control over the spray volumes and locations and reduced die change times. Fluid disposal was eliminated as well.

New lube gives the slip to stamper's slips, trips, and falls

October 9, 2007

By:

KI USA, a division of KI Japan, stamps and produces sub-assembly parts for Toyota, Honda, Nissan, and other "transplant" automotive OEMs. The stamper wanted to improve plant safety by reducing incidents of slips and falls. Petroleum-based stamping lubricants that had been used created a slippery environment at the press and other sites. Changing the stamping lubricant system to a synthetic lubricant from MS Fluid Technologies not only improved plant safety and appearance, it produced cost savings and reduced the plant's impact upon the environment.
