Hongtu Glasses Launches New-Generation Frames: TR90, CP and PC Injection-Molded Materials Upgrade Eyewear Performance

Hongtu Eyewear has expanded its injection-molded eyewear frame range with three material options: TR90, CP (cellulose propionate) and PC (polycarbonate). The new range is designed for different eyewear applications, including sunglasses, optical frames and children's glasses, giving distributors and OEM/ODM buyers more flexibility when selecting frame materials for different markets.

Frame material has a direct influence on weight, flexibility, impact resistance, surface appearance and wearing comfort. Instead of using one material across different product types, Hongtu Glasses offers TR90, CP and PC injection-molded frames to match different product requirements and target user groups.

TR90 Frames for Lightweight and Flexible Eyewear

TR90 is known for its low weight and flexibility, making it suitable for eyewear designed for extended daily wear. Its flexible properties allow the frame to withstand repeated bending during normal use, while its lightweight construction helps reduce pressure on the face.

These characteristics make TR90 frames suitable for everyday optical eyewear and children's glasses, particularly where flexibility and wearing comfort are important considerations.

CP Frames for Surface Finish and Color Options

CP, or cellulose propionate, is used for frames that require a smooth surface finish and a wider range of color combinations. Compared with more basic injection-molded materials, CP can provide a more refined appearance for frame fronts and temples.

Its balance of hardness and toughness makes CP suitable for fashion sunglasses and casual optical frames. It also provides flexibility for OEM and ODM programs that require different frame colors and visual effects.

PC Frames for Impact Resistance

PC (polycarbonate) is selected for applications where impact resistance and toughness are important. The material can better withstand drops and everyday collisions, making it suitable for frame designs that require higher resistance to accidental impact.

Hongtu Glasses uses injection molding to produce PC frames with consistent dimensions and wall thickness. This helps maintain product consistency across larger production runs and supports the requirements of export orders.

One Frame Range, Three Material Options

The three material options allow buyers to select frames according to product positioning, application and target users. TR90 can be used for lightweight and flexible eyewear, CP for appearance-focused designs with broader color options, and PC for applications where impact resistance is a key requirement.

Quality Control for Injection-Molded Frames

Hongtu Glasses applies quality checks throughout the production process, including incoming raw materials, injection molding and finished frames. Process control focuses on dimensional consistency, appearance and overall frame quality to support stable production for export orders.

The material-based product range also gives overseas buyers more options when developing eyewear for different price segments, user groups and market requirements.

OEM and ODM Frame Customization

The new TR90, CP and PC injection-molded frame range is available for OEM and ODM projects. Hongtu Glasses can develop customized frame shapes, colors and surface treatments according to customer requirements, helping buyers build frame collections for different eyewear categories and markets.

With multiple injection-molded material options in one product portfolio, Hongtu Glasses provides buyers with a more practical way to match frame construction with the intended application and product design.
