01 · The challenge
Northvale needed a second source for an actuator housing with 140 features and tight positional tolerances. Their previous supplier needed four setups and scrapped one part in twelve.
02 · Our approach
We redesigned the fixturing so the housing is finished in two setups on our 5-axis cell, and added in-process probing on the bore positions. First article was signed off at the first attempt.
03 · The result
Three years and over 7,000 housings later, no non-conforming part has reached Northvale. Lead time fell from ten weeks to six.
“Holloway took a part everyone found difficult and made it boring. That is the best thing I can say about a supplier.”
