| In
a business where every second counts, ITT Bell and Gossett finds
a way to cut down months of production time, without cutting
down on quality. Continuous process improvement is part
of their managerial philosophy. One of the manufacturing
groups within this dynamic company, Domestic Products,
was able to eliminate production inefficiencies, while
enhancing overall quality.
Domestic Products produces boiler feed, condensate
return and industrial vacuum units. These high temperature
water systems require special 2 foot NPSHR pumps. These
packaged units and pumps go through a series of performance
and operational tests, before ITT Bell and Gossett will
put its name on them. The quality and durability of these
products is critical to their effectiveness in HVAC systems
in schools, hospitals, and residential buildings.
Each pump goes through rigorous hydraulic
testing before a nameplate is affixed containing all the
pump's specifications. Formerly, a test technician dealt
with a flood of paperwork for each test unit. "When
you consider the number of nameplates we make, this wound
up costing the company months in lost production time.
The process was an obvious opportunity for process optimization," said
Chief Product Engineer for Domestic Products, Chris Mah. "The
nameplates that were produced were not the desired result
of something that consumed so much time," continued
Mah.
Mah began to take a critical look at their
testing procedures and formed a task team to automate the
process. The team consisted of Product Engineer, Brian
Schnelzer, I.S. Mike McCabe and Mah the project leader.
After carefully mapping out the order of the specification
data stream and actual test data flow, the team began to
review marking companies. When reviewing these companies,
ITT Bell & Gossett was looking for a company that would
not only provide a product, but also a project partner
who felt a vested interest in their success. Geo. T. Schmidt,
Inc. fulfilled both needs.
In reviewing the internal test procedures,
the team found two complications that quickly eliminated
vendors. One was the varying size of nameplates containing
varying data strings. The other was the masking that covers
the nameplate face. This mask protects the data on the
nameplate from paint that is applied to the unit before
shipment. Schmidt's Styliner Mark4 was the only system
that did not tear the masking.
The Styliner Mark4 is both flexible and fast.
The Styliner uses a computer controlled stylus tip, made
of carbide, that acts as a mini jack hammer that can mark
a wide variety of parts at varying speeds and character
heights. It can also mark logos, serialize part numbers,
date codes, and store a large number of files.
Today in the Domestic Products factory, all
order specifications are electronically passed to overhead
PC monitors at the pump test racks. A technician enters
the order information into the Styliner system and with
one keystroke, the test data is captured and automatically
analyzed. If approved, the test procedure advances the
automated test to the next stage of testing. Once testing
is complete a nameplate with a minimum of 18 fields containing
test information is produced in seconds. Every nameplate
that is produced has characters that are even, straight,
of uniform depth, height and clearly visible. In addition
the nameplate remains flat, which provides a uniform system
for adhesion and a professional appearance.
Aside from the reduction in overall
handling time and virtually eliminating marking errors,
ITT Bell & Gossett has been able to expand the accessibility
of test results. "Using the database and data acquisition
cards we are able to greatly simplify the collection
and analysis of test data. In addition, we are able to
have on line viewable test sheets through out the building," says
McCabe explaining some of the benefits of the new nameplate
system. This enables anyone to readily access a specific
order's test results. ITT Bell & Gossett is in the
process of making these records available to their salesforce
through the Internet. This will enable the salesmen to
quickly access order history and replacement part information
from the field.
