Product Features

CP Injection Sunglasses are produced using injection-molded plastic frames and pin-insert temple structures, offering an optimal balance between cost efficiency, structural stability, and mass-production scalability.

Compared with traditional acetate or metal frames, CP injection sunglasses provide lighter weight, consistent dimensions, and faster production cycles, making them ideal for wholesale, private label, and OEM sunglasses programs.

Key features include UV400 lens compatibility, uniform surface finishing, stable hinge performance, and flexible color customization through injection molding. These advantages allow eyewear brands and distributors to maintain competitive pricing while ensuring reliable quality across large-volume orders.

CP injection sunglasses are widely chosen by global buyers seeking factory-direct sunglasses manufacturers capable of supporting bulk orders, custom logos, private label packaging, and long-term supply partnerships for international markets.

CP Pin Injection vs Full Injection vs Acetate Sunglasses

Buyer-Oriented Material Comparison

1.CP Pin Injection Sunglasses

Best balance between cost, stability, and scalability

CP pin injection sunglasses combine injection-molded plastic frames with reinforced pin-insert temple structures, delivering better durability than full injection frames while maintaining efficient mass production.

They are widely chosen by sunglasses wholesalers and private label brands seeking reliable quality, stable hinges, and competitive pricing for bulk and repeat orders.

2. Full Injection Sunglasses

Maximum cost efficiency for large-volume programs

Full injection sunglasses are manufactured as a single molded piece, offering the lowest unit cost and fastest production cycle.

This option is ideal for promotional sunglasses, entry-level retail programs, and buyers prioritizing price, fast delivery, and large-scale production consistency over premium detailing.

3. Acetate Sunglasses

Premium appearance and design flexibility

Acetate sunglasses are produced from laminated cellulose acetate sheets, allowing greater design depth, layered colors, and a higher-end tactile feel.

They are best suited for fashion brands and retailers focused on design differentiation, retail presentation, and premium positioning rather than maximum cost efficiency.

Buyer Recommendation 

If you are sourcing sunglasses for bulk wholesale or private label programs, CP pin injection sunglasses offer the best balance of durability, consistent quality, and cost control.

For extremely price-sensitive, high-volume orders, full injection sunglasses provide the lowest unit cost and fastest production.

If your priority is premium appearance and design flexibility, acetate sunglasses remain the preferred choice despite higher cost and longer lead times.
