Superior Air Parts Improves Push Rod Seal Design And
Manufacturing
Call it a simple 'fix'
for a persistent problem. Superior Air Parts' Product Integrity
Team (PIT), a group of employees representing all facets of the
company and responsible for identifying and solving product
performance and quality problems have recently developed a new push
rod seal that would provide a much better solution to the issue of
bad seating and fluid leaks.
"We had heard comments from some customers that our push rod
seals didn't install very well," explained Keith Blockus,
Superior's Sr. Director of Engineering and Product Development.
"They were hard to get seated and would sometimes leak."
"Our PIT Crew traced it
to inconsistencies in the manufacturing process," he continued. "We
had a meeting with the part's supplier and he understood the
problem and was very proactive in finding a solution."
Blockus said the solution was to switch manufacturing processes
away from the inconsistencies of machining the seals from a piece
of frozen rubber to a state-of-the-art injection molding system
that created a perfect circle every time. "The vendor produced some
samples of the injection molded part and we sent it along to our
customers for their review," he continued. "They thought it was
fantastic. It met all their needs perfectly."
"The PIT Crew led the entire year-long process from design
changes to manufacturing samples to customer testing and onto final
production," Blockus continued. "They even specified a new color so
there would be no confusion in the field. The old parts were white,
and the new ones are 'Superior Blue."
