TR90 Frames for Lightweight & Flexible Custom Eyewear
TR90 is commonly considered for eyewear projects requiring lightweight frame construction, practical flexibility and a different production route from sheet-based acetate or metal eyewear.
Frame geometry, wall thickness, hinge design, color and production feasibility should be reviewed together before sample development.
Why Consider TR90 for Eyewear Frames?
TR90 is often selected when brands want a lightweight and practical frame direction that differs from traditional acetate and thin metal construction.
Lightweight
TR90 can support eyewear designs where reduced frame weight is an important product objective.
Flexible Structure
Appropriate frame designs can take advantage of the material's flexible characteristics.
Practical Design
Suitable for everyday, active and selected children's eyewear concepts.
Molded Construction
TR90 uses a different manufacturing route from CNC-machined acetate frames.
Flexibility Depends on Material and Frame Geometry
A flexible material does not mean every finished frame can be bent without considering its structure.
Rim thickness, bridge geometry, temple dimensions, hinge connections and molded details all influence how the finished TR90 frame behaves.
- Frame-front wall thickness
- Bridge construction
- Temple cross-section
- Hinge integration
- Integrated nose-pad geometry
- Overall frame structure
TR90 Should Match the Intended Eyewear Application
Material choice should match the intended product, target wearer, frame geometry and manufacturing method.
TR90 may be considered for lightweight everyday frames, selected children's eyewear and active-use concepts, subject to sample validation.
- Optical eyewear
- Sunglasses
- Kids eyewear
- Lightweight everyday frames
- Selected active-use eyewear
- OEM and private label collections
TR90 Frame Profile
TR90 vs Acetate Eyewear
TR90 and acetate use different material systems and manufacturing routes, so they should not be treated as interchangeable frame materials.
| Area | TR90 | Acetate |
|---|---|---|
| Typical Direction | Lightweight, flexible and practical eyewear. | Premium, fashion, color and pattern-led eyewear. |
| Manufacturing Route | Molded frame construction. | Sheet preparation, CNC machining and polishing. |
| Appearance | Clean molded surfaces and practical frame profiles. | Rich patterns, transparency, polishing and material depth. |
| Flexibility | Can support flexible structures depending on geometry. | Generally used for more rigid sheet-based structures. |
| Collection Positioning | Everyday, lightweight, kids or active-use concepts. | Designer, fashion, premium and lifestyle collections. |
TR90 Uses a Molded Manufacturing Route
Unlike acetate frames machined from sheet material, TR90 frame structures are produced through a molding-based manufacturing process.
Mold geometry, material processing, demolding, trimming and later assembly all contribute to the final frame quality.
- Raw material preparation
- Injection molding
- Controlled demolding
- Trimming and finishing
- Component assembly
- Dimensional inspection
From TR90 Frame Design to Finished Eyewear
Frame geometry, molding structure, component installation and quality control should be considered as one development process.
Frame Development
Review frame geometry, dimensions and structural requirements.
Mold & Process Review
Evaluate how the approved frame translates into the molding process.
Sample Production
Produce samples to evaluate structure, fit, color and assembly.
Assembly & QC
Inspect dimensions, hinges, lens fit, alignment and finish.
Where Can TR90 Frames Be Used?
The best application depends on frame structure, target wearer, lens requirements and collection positioning.
Optical Frames
Lightweight optical frame concepts designed for everyday use.
Sunglasses
Practical sunglass frames for lightweight collection directions.
Kids Eyewear
Lightweight and flexible concepts can be considered for children's frames.
Active Eyewear
Selected active-use concepts where practical frame structure is important.
What Should Be Confirmed Before Sampling?
TR90 projects should begin with clear frame structure, material, color and product-use requirements.
Frame Geometry
Confirm lens shape, bridge structure, frame width and temple design.
Wall Thickness
Component thickness should suit the frame design and intended flexibility.
Hinge Design
Hinge construction should integrate correctly with the molded frame structure.
Color Direction
Confirm required colors, finish and collection consistency.
Lens Compatibility
Lens shape and groove structure should be reviewed with the intended lens type.
Branding
Logo placement and private label requirements should be included during development.
Lightweight Frames Still Require Precise Inspection
Flexible positioning does not remove the need for dimensional accuracy, stable hinge operation, controlled alignment and consistent surface quality.
Finished frames should be checked against the approved sample and relevant project specifications.
- Frame front dimensions
- Lens width and height
- Bridge dimensions
- Temple length
- Hinge function
- Frame alignment
- Flexibility review
- Surface quality inspection

TR90 Eyewear FAQ
What is TR90 eyewear?
TR90 eyewear generally refers to frames produced from a lightweight thermoplastic material used for molded frame structures. The exact material specification should be confirmed for each project.
Are TR90 frames flexible?
TR90 can support flexible frame designs, but actual flexibility depends on frame geometry, component thickness and structure.
Is TR90 lighter than acetate?
TR90 is often selected for lightweight frame concepts, while actual finished-frame weight depends on dimensions, wall thickness, hardware and lens design.
Can TR90 be used for kids eyewear?
TR90 can be considered for selected kids eyewear projects where lightweight and flexible frame characteristics suit the intended product.
Can TR90 be used for sunglasses?
Yes. Suitable TR90 frame structures can be developed for sunglasses depending on lens shape, dimensions and product requirements.
