😎 Ever wondered why acetate frames feel so different from regular plastic glasses?
It's all in the process.
A pair of acetate glasses goes through 7 precise steps before it reaches your customer — from raw cellulose sheet selection, to CNC milling, to 48 hours of barrel tumbling, to hand polishing, to a 5-point QC check.
Skip the tumbling? The frame feels rough. Rush the polishing? The gloss is uneven. There's no shortcut.
At JM Optical, we've been making acetate frames in our Wenzhou factory for 20 years. Here's the full process — from raw sheet to finished frame.
If you're sourcing eyewear from China, understanding this process helps you:
• ✅ Set realistic lead times (60–90 days for OEM, 7 days for stock)
• ✅ Evaluate supplier capability — ask about their polishing process
• ✅ Explain pricing to your retail customers with confidence
