INJECTION / PLASTIC SUNGLASSES
Injection-Molded Sunglasses Built for Consistency at Scale
A production-focused frame approach designed for repeatable geometry, dependable structure, and stable supply across scalable programs.
Frames only. Lenses are not included.
Overview
What Injection / Plastic Sunglasses Mean
Injection / plastic sunglasses are frames produced through molding processes that prioritize repeatable shape and dimensional control.
This category is often selected for programs where stable batches, consistent appearance, and predictable production planning matter.
For brands running long-term SKUs or high-volume releases, injection-molded frames support reliable scaling without sacrificing structural clarity.
Why Injection
Why Injection-Molded Frames Are Chosen
Predictable geometry
Mold-controlled shape supports consistent production outcomes.
Program-friendly scaling
Suitable for planned releases, recurring orders, and long-term supply.
Clear production planning
Tooling-based manufacturing supports repeatable schedules and stable batches.
Advantages
Key Advantages for Scalable Sunglasses Programs
Repeatable Shape Control
Designed to keep frame geometry consistent across batches.

Consistent Design Extensions
Supports colorways and series development without reinventing the structure.
Material Comparison
Injection Plastic Compared to TR90 and Acetate
Different materials are selected for different goals — flexibility, texture, or repeatable production.
| Feature | Injection Plastic | TR90 | Acetate |
|---|---|---|---|
| Primary value | Batch consistency and scaling | Flex and resilience | Rich texture and premium feel |
| Shape repeatability | High | Medium | Medium |
| Flexibility | Low–Medium | High | Medium |
| Visual character | Clean and controlled | Functional and minimal | Deep, expressive |
| Best for | Long-run SKUs and volume programs | Active-use programs | Lifestyle and premium lines |
