## Frequently Asked Engineering Questions (FAQ)

### Do you sign mutual NDA before reviewing 3D CAD designs?
Yes, absolutely. A mutual Non-Disclosure Agreement (NDA) is standard protocol at KONAR prior to receiving any drawings, 3D models, or product specifications.

### What is the minimum batch size for custom OEM production at KONAR?
A cost-effective production run begins at 50 to 100 units per model, optimizing CNC setup time and delivering competitive factory-direct pricing.

### Do you produce prototype units prior to mass production?
Yes, every OEM contract begins with 1–2 master prototypes shipped to the client for dimensional validation, upholstery fitment, and finish sign-off.

### How is batch quality assured before dispatch?
We implement AQL (Acceptable Quality Limit) Level II sampling, including cross-cut adhesion tests (ISO 2409) for lacquered surfaces and trial assembly of 5% of each production batch.
