Cost recovery · Save value already in the lite
Recover suitable finished glass before a surface defect becomes scrap, remake time or a missed shipment.

WHY EVALUATE RESTORATION
For suitable conditions: lower total cost, faster resolution, controlled quality
These are decision criteria, not universal promises. Confirm the glass, condition, access and acceptance requirements through a representative trial.
Compare restoration with remake, handling and disruption costs for suitable panes.
Evaluate a recovery path before committing to remake lead time.
Set acceptance with QA, then inspect and document the result.

THE DECISION
A practical restoration decision
A late-stage surface defect can trigger a hold, rework or a remake. Evaluate restoration before writing off the value already in the part.
FROM ASSESSMENT TO ACCEPTANCE
Move one held lite from defect record to disposition
Use a bounded plant trial to answer a real QA question before restoration is added to production work.
- Record the lite, glass build and defect at the point it is found.
- Select a representative held lite and write the acceptance check.
- Run the approved trial with a trained operator and controlled setup.
- QA records restore, rework, escalate or remake - then decides whether to repeat.
TECHNICAL DETAIL
Use the decision model in this work environment
Prevention cost
Training, handling controls, washer maintenance and process changes intended to keep the defect from occurring.
Appraisal cost
Inspection, sampling, classification and the time required to decide whether a lite meets the requirement.
Internal failure cost
Held inventory, in-plant handling, restoration trials, rework and remakes found before shipment.
External failure cost
Field discovery, replacement logistics, schedule effects and stakeholder coordination after shipment or installation.

YOUR NEXT MOVE
Cost recovery · Save value already in the lite
Start with one recurring defect and one held-lite trial. GlassRenu can help frame the pilot, operator requirements, inspection record and equipment path; larger programs can also use a paid technical assessment or consulting engagement.
COMMON QUESTIONS
Before a pilot or project begins
Is every production defect a restoration candidate?
No. Glass construction, coatings, damage location and acceptance requirements must be identified first. Keep a clear escalation and replacement pathway for unsuitable conditions.
What should a pilot measure?
Record setup and repair time, inspection outcome, rework, consumables and the comparable remake scenario. Use observed results rather than a generic savings promise.
READY TO CONTINUE?
Recover suitable finished glass before a surface defect becomes scrap, remake time or a missed shipment.
Give QA and production teams a controlled restoration pathway for selected surface damage.
