Grinding is one area where automation such as the use of this robotic equipment is providing numerous benefits.
about 130 now and, when the economy was roaring, about 190 employees.”
Sharing Information As the company expanded and added
capacity, communication with employ- ees became more important than ever. Automation increased significantly in the first phase of the company’s major expansion, which requires training on new practices for long-term employees as well as new and recent hires. “If you brought my grandfather
back and took him through the plant, he’d be pretty confused until he got to the grinding room,” Davies said, “because it’s the same as it used to be, while everything else is more automated now. Tat’s not some- thing people want to do, standing at a grindstone all day.” Te grinding room has six robotic systems, now, which don’t eliminate the worker from the line but make the work less physically demanding. “A couple years ago more than 50% was being ground on [the new systems], and it’s 70% to 80% now, by weight,” he said. On the SPO molding line, small
cores are set by hand and larger ones are set by hoist. “We want to do it as

STAINLESS STEEL CABINET
ALUMINUM MELTE RS! T.R.P. Vacuum Tester (True Reduced Pressure)
• Measures the absolute vacuum level, eliminating the need for daily/weekly/monthly calibration of the differential gage used on most RPT units.
• Fully automatic operation to pull the absolute vacuum to a target level, run a timed cycle, and dump the vacuum.
Typical One Month Variation in Unadjusted Test Chamber Vacuum Levels
• A special vacuum chamber is provided with a high temperature glass cover to permit observation of solidifying metal.
• The system utilizes a special cup to minimize variability in sample weight.
-25 “Hg, S.G.: 2.47
-26 “Hg, S.G.: 2.36
The plot shows the extent of testing errors created by not adjusting for changes in atmospheric pressure, as measured by traditional vacuum gages.
Replace subjective comparisons to visual standards with a proven method of quantifying Specific Gravity (S.G.) and % Porosity in vacuum test samples and casting sections.
