How We Work
Your Vision, Our Engineering
At CHENGYE OPTICAL, every project starts with understanding your brand. We don’t stock catalogs — we build custom solutions. Whether you need a single prototype or 100,000 units, our team ensures every frame meets your quality standards and aesthetic vision.
01
Consultation
Share your brand identity, target market, and design direction. Our team analyzes feasibility and proposes material and construction options.
02
Design & Development
Our in-house designers create 2D/3D renderings and technical drawings. We iterate with you until every detail is perfect before prototyping.
03
Prototyping
Rapid sample production using CNC precision machining. We deliver physical samples for your review, testing, and approval before mass production.
04
Mass Production
Full-scale manufacturing with rigorous QC at every stage. From raw material inspection to final packaging, we maintain consistent quality across all units.
Our Facility
Workshop & Production Floor
State-of-the-art CNC machining centers and precision polishing facilities serving 28+ years of eyewear manufacturing excellence.
Material Mastery
Expertise Across Materials
We work with the full spectrum of eyewear materials — each demanding its own precision techniques. Our engineering team understands the unique properties, challenges, and possibilities of every material we handle.
Primary Material
Acetate Frames
Cellulose acetate is the gold standard for premium eyewear. Our craftsmanship shines in rich tortoiseshell patterns and sculptural round frames, sourcing from world-class suppliers including Mazzucchelli 1849 and Panlite, with over 500 colorways and textures.
- Multi-layer lamination and bio-acetate options
- Precision CNC cutting with hand-finished edges
- Custom color matching and pattern development
- Rich tortoiseshell, marble, and bio-acetate patterns available
- Metal-core reinforcement for structural durability
Metal Engineering
Our metal workshop handles everything from surgical stainless steel to Monel and advanced alloys. Each material requires specialized welding, soldering, and surface treatment expertise.
- Stainless steel (304/316L) and Monel alloy frames
- Laser welding and precision micro-soldering
- Electroplating: IP gold, IP rose gold, gunmetal, silver
- Rimless, semi-rimless, and full-rim constructions
- Hypoallergenic options for sensitive skin markets
Titanium & Beta-Titanium
Titanium represents the pinnacle of eyewear engineering — ultra-lightweight, corrosion-resistant, and hypoallergenic. Our CNC workshop achieves tolerances of 0.01mm for titanium frame components.
- Pure titanium and Beta-titanium construction
- 5-axis CNC machining for complex geometries
- Frames as light as 12 grams without compromising strength
- Japanese-standard beta-titanium wire bending
- Ideal for premium and medical-grade optical frames
