Hand Made

Hand Made Cellulose Acetate Sunglasses

1. Material Preparation:

   • Cellulose Acetate Sheets: Large sheets of cellulose acetate, derived from wood pulp and cotton fibers, are manually cut into smaller pieces for frames.
   • Color and Pattern Selection: Craftsmen select and cut sheets based on desired colors and patterns, often aligning patterns meticulously.

2. Cutting and Shaping:

   • Manual Cutting: Frames are cut from acetate sheets using saws or CNC machines, then individually shaped and smoothed by hand.
   • Heating and Forming: Frames are heated and bent manually to achieve the correct curvature and fit.

3. Polishing:

   • Multi-step Polishing: Frames undergo multiple rounds of polishing using tumblers, cloth wheels, and hand polishing techniques to achieve a smooth, glossy finish.

4. Assembly:

   • Precision Assembly: Components like hinges are meticulously attached by hand, ensuring precise alignment and durability.
   • Custom Adjustments: Frames are adjusted for comfort and fit, often tailored to individual specifications.

Traditional Plastic Sunglasses

1. Material:

   • Injection Molding: Sunglasses are made from liquid plastic injected into molds, typically using materials like polycarbonate or nylon.

2. Mass Production:

   • High Volume Production: Frames are produced in large quantities rapidly, with minimal variation in design and quality.

3. Finishing:

   • Basic Polishing: Post-molding, frames may undergo basic machine polishing, lacking the intricate finishing of handmade acetate.

4. Assembly:

   • Automated Assembly: Hinges and other components are often attached using automated processes, prioritizing speed over precision.

Key Differences

• Material Quality: Cellulose acetate is more durable, flexible, and hypoallergenic compared to many injection-molded plastics.
• Craftsmanship: Hand-made acetate sunglasses involve extensive manual labor and quality control, resulting in unique, high-quality products.
• Customization: Handmade sunglasses offer greater scope for custom designs and adjustments.
• Production Scale: Traditional plastic sunglasses are designed for mass production, leading to lower costs but also a larger negative impact on the environment.
