Precision
Acetate Line
Our acetate line transforms cellulose acetate sheets into finished frames through a precise sequence of heating, CNC machining, bending, and assembly. Each stage is designed to preserve the material’s natural characteristics while maintaining the dimensional consistency that brand specifications demand.

How Every Pair Gets Made
Every frame moves through a defined production sequence — from raw material intake to final inspection — with quality controls built into each stage of the process.
Reality Features
Brief received, specifications confirmed, and samples developed for client approval. Full Customization.
Material Sourcing
Components and raw materials sourced and inspected against quality standards before entering production.
Manufacturing
Frames produced on dedicated production lines with automated equipment and process controls in place.
In-Process QC
Strict and fully In-Process Quality Control checks carried out at critical stages throughout the production run.
Final Inspection
Every finished pair is cleared through 100% individual inspection before leaving the production floor.
Packaging & Delivery
Orders packed to client specifications and shipped on the agreed timeline, with all necessary documentation.
The Equipment Behind Our Output
Our facility runs on advanced automation equipment maintained and operated by a team of experienced engineers and technicians — the hardware that makes consistent, high-volume production possible.
