Advanced Tire and Wheel Bead Seating System

Kokusai was
approached by a European company that outsources tire and wheel assemblies for
a European car manufacturer. Their
interest was in Kokusai’s bead seating operation, as their current suppliers
had issues with effectiveness and potential damage to tire & wheel
assemblies. Initially, Kokusai was not
an approved supplier for either the outsourcing company or the final
manufacturer. In order for Kokusai to
become certified, they had to run bead seating operations on the car
manufacturer’s tire and wheel assemblies, followed by various tests to ensure
successful operation. The first test run
was at an existing Kokusai customer’s location in the middle of the night,
while operations were shut down in between their second and first shifts. The outsourcing company then took the tire
and wheel assemblies and ran them through their measurement equipment to verify
proper bead seat. Preliminary results
were acceptable; however, the customer requested additional real world tests. A large number of wheels and separate tires
were then shipped to Kokusai. For the
next test, Kokusai mounted and inflated the tires and wheels in a very short
time period prior to the bead seating operation, as they would in production
mode. The customer’s personnel reviewed
the tests on the latest version of the all-electric servo bead seater
model. These assemblies were then sent
back for measurement verification. After
this process, the European car manufacturer approved the Kokusai bead seat
machine and process. The Kokusai current
bead seating model would normally transfer the tire and wheel assemblies using
an overhead transfer system, but the car manufacturer would not allow the wheel
face to be touched, even though previous models showed no marking. Kokusai redesigned the transfer mechanism to
hold on to the outside of the tire rather than holding the wheel surface, thus
avoiding any issues.
