Quality control in glass manufacturing is notoriously difficult due to the material’s transparent and brittle nature. Here, we address the five most frequent challenges reported by our global partners and how Jeffoptics technology solves them.
Q1 How do we handle "Spontaneous Breakage" in high-rise buildings?
The Problem: Nickel Sulfide (NiS) inclusions can cause tempered glass to shatter months after installation. The Solution: While Heat Soak Testing is standard, measuring the residual surface stress with our JF-1 series ensures the tempering process hasn't created excessive tension, which exacerbates the NiS risk.
Q2 Why is my stress measurement inconsistent across the same sheet?
The Problem: Uneven cooling in the tempering furnace. The Solution: Use a multi-point measurement strategy. Our portable stress meters allow operators to quickly check the center and all four corners, providing a map of the furnace's cooling efficiency.
Q3 Measuring curved glass is difficult; the sensors won't sit flat.
The Problem: Standard refractometers require a flat surface for a proper optical seal. The Solution: Jeffoptics has engineered specialized curved-surface adapters and flexible optical interfaces for our JF-3 series, allowing for accurate readings on automotive sidelites and architectural curved glass.
Q4 We are moving to thinner glass (under 2mm). Can we still measure stress?
The Problem: Thin glass creates complex interference patterns that overwhelm standard meters. The Solution: The JF-2E Digital Stress Meter uses a higher frequency optical path and specialized algorithms to isolate the surface stress in ultra-thin glass used in electronics and solar panels.
Q5 How can we reduce the time taken for QC reporting?
The Problem: Manual data entry is slow and leads to transcription errors. The Solution: Our devices feature Bluetooth and USB connectivity. Data is pushed directly to a centralized database, generating a PDF certificate of compliance instantly.
