Why Bead Volume — Not Just Width — Determines Adhesive Joint Quality
When your team talks about product quality, what comes to mind? For many manufacturers, the answer is long-term reliability — especially when it comes to adhesive and sealant joints. But ensuring that reliability requires looking beyond surface-level measurements.
Why Adhesive Volume Matters More Than Bead Width
It’s easy to assume that a wider adhesive bead means a better bond. But that assumption can be misleading. A wide, flat bead might look adequate, yet contain significantly less material than a narrow, taller one. The true indicator of joint strength is not width alone, but the actual volume of adhesive dispensed per millimeter.
Several variables affect this volume:
- Material viscosity
- Robot movement speed
- Nozzle wear and tear
- Dispensing system calibration
Even subtle changes can impact bead shape, and in turn, the amount of adhesive applied — directly influencing the durability and performance of your product.
The Solution: Real-Time 3D In-Line Inspection
To ensure consistent adhesive application and high joint integrity, manufacturers need precise, in-line bead volume measurement — not post-process inspections or visual checks. That’s where Coherix 3D technology comes in. Our in-line 3D inspection systems measure dispensed bead volume in real-time, right on the production line.
This allows your team to:
- Monitor and correct dispensing variability instantly
- Prevent weak joints caused by under-application
- Maintain consistent quality across every part
- Reduce material waste and rework costs
Eliminate Guesswork. Ensure Reliability.
With Coherix 3D, you gain true process control — not just the illusion of quality. Don’t leave adhesive performance to chance. Inspect what really matters: volume per millimeter.
