WHY SEESUN
As a sunglasses manufacturer in China, SEESUN helps global eyewear brands move from design to reliable production through in-house R&D, complex eyewear engineering, faster sampling and flexible lean manufacturing.
Our experience covers acetate, metal, titanium and mixed-material eyewear, with close control of fit, construction, finishing and production consistency.
01
Approved designs can lose accuracy when translated into production.
In-house product development helps optimize construction early and control proportions, fit and critical details from sample to production.
02
Complex structures and mixed materials increase manufacturing risk.
Experienced in acetate, metal, titanium and mixed-material constructions, including demanding structures and intricate design details.
03
Slow sampling and repeated revisions delay product launches.
15–20 DAYS*
Typical development time for standard acetate samples.
04
High-mix, lower-volume orders make scheduling, consistency and delivery harder to control.
60-75 DAYS*
Lean production management and flexible scheduling support multiple styles and smaller runs while maintaining stable quality and delivery.
*Lead times vary by design complexity, materials, finishing requirements, order quantity and production mix.

OUR FACTORY
Our China eyeglasses factory supports OEM & ODM production for sunglasses and optical frames, from precision machining and hand finishing to inspection and packing.
Precision CNC machining for frame components, prototypes and production parts with consistent dimensions and structural accuracy.
Barrel tumbling removes CNC cutting marks and rough edges from acetate frame components before further finishing.
Skilled hand polishing refines surfaces, edges and details for a smooth, high-quality finish.
Skilled assembly and fitting ensure proper alignment, smooth hinge operation and consistent frame structure.
Each finished frame is checked by the operator before careful packing and preparation for the next quality-control stage.
Finished eyewear undergoes final inspection for appearance, alignment, function and overall quality before shipment.
