Glass Fabrication Wraps Up Today in Orlando
Glass Association of North America's Glass Fabrication 2006 will
conclude today in Orlando. Approximately 140 attendees are taking
part in the event, which is focusing on insulating, laminating and
tempering fabricating techniques and procedures.
This morning opened with a discussion on glass breakage from Bob
Maltby of R&D Reflections. Maltby covered the reasons glass
can break, such as tensile stress and cracks. He emphasized that
glass breaks in tension and when it has flaws. He said that glass
strength is probably not the same for two pieces of glass with the
same history. Maltby also covered different types of stress as well
as thermal breaks.
Following Maltby was a standards discussion led by Henry Gorry and
Kevin Olah, both of Guardian Industries, and Valerie Block of Dupont.
They talked about three ASTM standards: C 1036, Standard Specification
for Flat Glass; C 1048, Standard Specification for Heat-Treated
Glass; and C1172, Standard Specification for Laminated Architectural
Glass. In the presentation, the three explained the purpose of each
standard, as well as how and by whom they are used. Olah stressed
that standards are voluntary and do not take the place of any building
Rosie Hunter, also with Guardian Industries, followed with a discussion
on glass coatings in architectural design. She covered different
types of glass coatings and trends in the commercial market (such
as an increasing amount of transparency). She also showed pictures
of a variety of different applications that showed different types
of glass usage.
Julie Schimmelpenningh of Solutia spoke next on laminated glass.
She began with a description and explanation of what laminated glass
is and the applications for which it can be used. Application trends,
she said, include safety, security, sound, solar and style. The
style application has begun to be increasingly appealing to architects
due to the many options laminated glass affords, including color
choices and graphic design capabilities, Schimmelpenningh said.
The morning's final session was lead by Jill Nowak of Viracon who
talked about time studies and efficiency planning using lean manufacturing.
The purpose of a time study, she said, is to evaluate individual
process rates and to establish equivalencies. She explained that
following "lean" procedures is not about manufacturing
more quickly, but more efficiently.
"The goal of lean manufacturing is to eliminate waste in our
process, as seen through the eyes of the customers," she said.
Her reasons for doing time studies included: becoming more knowledgeable
about processes; establishing a baseline using the most common product
produced; creating equivalencies for each product in the process
based on the relationship to the baseline product; and creating
a process model.
"If we don't understand the process, we can't make knowledgeable
decisions moving forward," she said.
This afternoon Glass Fabrication attendees will again split into
break-out sessions to focus on their specific work focus areas,
be it insulating laminating or tempering.
Meetings will conclude today.
