Hinge Plastic Encapsulation

One of our vital pre‑tumbling protective procedures for premium eyewear frames.

Before frames go into barrel tumbling polishing, we encapsulate the precision hinge with protective plastic.

This custom shielding layer isolates hinges from friction and impact inside the tumbler drum, effectively avoiding micro‑scratches on delicate metal hinge surfaces, while maintaining original hinge tightness and metallic finish.

Tiny hinge scratches are easy to overlook, yet they ruin the quality of high‑end eyewear and trigger costly rework.

We take this extra protective step to stabilize yield and deliver consistent defect‑free frames for our brand partners.

Excellence is never an accident. It comes from every precaution built into our workflow.
