Glass Fabricators Speak to Sold out Event in Pittsburgh
Despite stormy weather in the Northeast, members of the glass
industry found good reason to travel into Pittsburgh today for the
start of Glass Fabrication 2007. The Glass Association of North
America (GANA) sponsors the insulating, laminating and tempering
educational seminars, which sold out this year.
Glass Fabrication is geared toward individuals who are first entering
the industry. This morning's session offered some basic information
to provide a level playing field for attendees who have been in
the industry five years or less and those few individuals in attendance
who have been part of this industry for more than 30, and even 40,
Scott Hoover of Pilkington first offered an overview of the history
of glass. Chuck Beatty of Edgeworks Inc. spoke next on the principles
and fundamentals of glass cutting. He discussed carefully scoring
glass with cutting wheels.
"What I'm suggesting is that glass has a skin," Beatty
said, "and that layer of skin is protecting a layer of tension
within the glass." He added, "It's the release of tension
that breaks the glass."
Beatty explained that it is necessary to choose the right tool
for the job and to know how much pressure to apply with the tool--as
well as the correct angle to use--to create only the desired fissure
and not subsurface breaks that can weaken the glass. He also encouraged
his audience to frequently change their cutting wheels.
Bob Lang with Billco Manufacturing Inc. also spoke about the importance
of maintaining tools. Specifically he stressed the importance of
proper maintenance for glass washing machines, as well as the importance
of using quality water for the rinse. As Lang noted, "The thing
to remember, if the inside of the glass washer is dirty, it can't
produce clean glass."
In addition to using quality water, Lang noted that more companies
are looking to use less water. "In more and more areas of North
America, companies are being asked to conserve water," he said.
He suggested re-circulating rinse systems or a closed loop water
filtering system to help use less water.
Tom Parseghian of Power Brushes Inc. also looked at cleaning the
cleaning equipment. He focused more specifically on maintaining
brushes. "It's tough to clean a brush," he said.
He warned people away from using power washers because it can permanently
bend and damage the brushes. He also warned that if storing brushes,
they should be stored so that the bristles are not fully supporting
the brush and so the bristles don't touch. "All brush material
has a memory, like carpet," he said.
If stored poorly, he suggested giving it some time and adding moisture
so that it returns to its original state.
Glass Fabrication continues through tomorrow at the Hyatt Regency
Pittsburgh International Airport.
