I describe, from my decades of experience in optical manufacturing, the step-by-step lens edging and fitting workflow used in a modern eyewear factory. The article covers inspection, blocking, CNC edging, beveling, rimless techniques, coatings handling, quality control against industry standards, and troubleshooting to ensure reliable fit for custom and mass-production frames.

I describe practical, production-proven injection molding workflows used inside an eyewear factory, covering mold design, material selection (PC, TR90, acetate), machine setup, process control, common defects and fixes, QC per industry standards, and how a vertically integrated OEM/ODM like Karuson optimizes throughput and reliability.

I explain, from material science to shop-floor practice, how an eyewear factory cuts and shapes acetate frames. The article covers acetate properties, step-by-step factory processes (CNC, laser, hand finishing), tooling, quality control against ISO standards, production comparisons, and recommendations for brands seeking OEM/ODM partners.

As an experienced eyewear factory consultant, I walk you through the complete production flow—from trend research and CAD design to prototyping, tooling, molding/CNC, finishing, QC and logistics—explaining materials, tech choices, standards and cost-quality trade-offs, with practical tips for OEM/ODM partners.
