Convox pitches Korean tech and China scale for optical lenses

Jiangsu Convox Optical is highlighting a cross-border manufacturing model that pairs South Korean optical engineering with China-based OEM production. The company says the setup is meant to give labs, chains and distributors high-performance lenses with faster replenishment and lower unit costs.

Why it matters: - Optical buyers want two things at once: advanced lens performance and large-scale supply. - Convox is positioning its manufacturing model as a way to reduce the trade-off between precision coatings, custom prescriptions and mass availability. - The pitch targets independent laboratories, optical chains and global distributors that need predictable inventory and faster delivery.

What happened: - Jiangsu Convox Optical described a sourcing model built around South Korean technical collaboration and China-based OEM manufacturing. - The company said its joint venture was established in 2007. - Convox said its facility in China produces premium resin lenses for international markets. - The company listed a corporate website at more information and an email contact at sales@convox.cn.

The details: - Convox said its production setup uses 16 Korean NVC vacuum coating machines for multi-layer anti-reflective and super-hydrophobic lens stacks. - The company said the coating process adds scratch resistance, hydrophobic and oleophobic performance, and anti-static characteristics. - Convox said its material lineup includes CR-39 at 1.499, 1.56 high-index polymers, 1.60 MR-8, 1.67 and 1.74 high-index resins. - The company said the 1.60 MR-8 material has an Abbe value of 41 and high impact resistance, making it suitable for rimless and nylon-compression frames. - Convox said 1.74 resin is designed for very thin lenses in strong prescriptions. - The company said it uses LOH VFT-Orbit fully automatic RX prescription equipment for digital freeform progressive lenses. - Convox said the same production line supports photochromic spin-coating systems and myopia-management lens options, subject to local regulatory requirements. - The company said its daily output capacity is 50,000 pairs of premium resin lenses across two automated production lines. - Convox said it keeps ready stock of single vision, bifocal, progressive, blue-block and anti-fog lenses across major refractive indices. - The company said its warehouse system holds finished single vision lenses and semi-finished blanks from 1.50 to 1.74. - Convox said its quality process includes five inspection steps for curvature and structural consistency before blanks move to coating or storage.

Between the lines: - The announcement is as much about supply-chain positioning as it is about lens chemistry. - Convox is selling a hybrid message: Korean engineering credibility plus China’s manufacturing scale. - That combination is aimed at buyers who want premium specifications without the lead times and cost structure of smaller specialty labs. - The emphasis on inventory depth suggests the company is also trying to compete on service reliability, not just product performance.

What's next: - Convox is inviting wholesale buyers to request technical data sheets, product sample kits and consultations for bulk OEM container distribution. - The company is also framing rapid replenishment as a key selling point for overseas distributors during peak demand periods. - The sourcing model appears designed to expand international procurement partnerships as demand for custom and high-index lenses grows.
