Case Study
Water Tightness Validation On A Container And Closure Pair
A customer project documented on our original site under the heading Water Tightness, covering a molded container and its matching closure.
Project Challenge
The Problem On The Table
A container and a closure can each pass dimensional inspection and still leak together, because the seal is a property of the pair and not of either part alone.
Customer Pain Points
- Leak failures appearing only after assembly and transport
- No single supplier able to change both halves of the interface
- Dimensional reports that proved nothing about sealing performance
Our Solution
What We Did
Both parts were held on tooling in our own plant, so the sealing land could be adjusted on one side or the other without a supplier negotiation. Water tightness testing was carried out on assembled pairs rather than on individual components.
Manufacturing Process
- Mold design covering both parts
- Cavity machining and EDM in house
- Cavity by cavity sampling
- Assembly and water tightness testing
Supply Chain
How It Was Coordinated
Holding both cavities in one plant removed the second supplier from the loop entirely, which is what made a same week correction possible.
Quality Control
Testing was done on assembled pairs, with results recorded against tool and lot in our ERP system.
Final Result
A container and closure pair validated together rather than separately, with the tooling for both under one roof for future corrections.
Customer Benefit
One supplier to call, one place to correct a seal, and a test result that reflects the product as it actually ships.
