From Uson, L.P.
International Truck and Engine Corp. produces commercial trucks, mid-range diesel engines,
school buses, chassis for motor homes and step vans, and diesel engines for the pickup truck,
van and SUV markets. The company's Advance Manufacturing Engineering Group had a system
for leak testing that was slow and not accurate enough.
"We primarily do mass-flow, pressure decay, vacuum decay and pressure-rise leak testing on our
diesel engines to make sure the components and assemblies don't leak beyond specifications,"
said Jim Bowman, senior manufacturing engineer for the Advance Manufacturing Group.
Leak testing speed and precision are both extremely important for companies like International
Truck and Engine, where even small leaks can mean the difference between product success
and failure.
"Cycle time is a huge factor," said Bowman. "The engines are on an assembly conveyor. As each
engine comes into the station you have an allocation of time to perform the work. You have 'x'
amount of time - usually a minute or less."
