Product Selling Points

1.  TR90 Front with CP Core Wire Temples

The front frame uses TR90, while the temples are made from CP with an internal wire core spring structure. This mixed-material construction gives the frame different functional roles: TR90 keeps the front lightweight, while the reinforced temple core provides structural support and flexibility around the temples.

2.  Spring-Action Temples for Everyday Flexibility

The wire core inside the temples works together with the spring mechanism to allow additional movement when the temples are opened and worn. Compared with a completely rigid plastic temple, this structure provides more flexibility around the side of the head and can make repeated daily opening and closing more comfortable.

3.  Layered Two-Color Frame Design

A deeper decorative layer is combined with a lighter main frame to create visible depth across the front and temple area. The layered color treatment gives the square frame more dimension without relying on an oversized or heavily decorated silhouette.

4.  Metal Temple-End Detail

A square metal accent is integrated at the end of the temple, adding a defined finishing detail to the otherwise molded construction. The small metallic element provides a visual transition between the CP temple body and the temple tip.

5.  Square Unisex Profile

The straight-line square frame keeps a structured appearance while remaining neutral enough for both men and women. Its 51-18-140 mm size supports a compact everyday optical format for commuting, office wear, and casual styling.

What Is a Core Wire Temple?

A core wire temple contains a metal wire structure inside the temple material. The internal core helps support the temple and allows it to be shaped or adjusted while maintaining the outer appearance of the molded temple. Core wire systems are commonly used when a plastic temple needs additional structural support and fitting flexibility.

In this model, the wire core is combined with a spring-style mechanism rather than using a simple rigid temple. This gives the side structure more movement while keeping the outer CP surface clean and consistent.

Why Combine TR90 and CP?

Using one material throughout the entire frame is not the only way to build a lightweight optical frame. The CP Core Wire Temple Unisex Casual Frames use TR90 for the front and CP for the temples so that the two sections can perform different roles within the same design.

TR90 provides a lightweight front structure, while the CP temple accommodates the internal wire core and spring construction. The result is different from an all-plastic frame with fixed temples and also avoids the full-metal construction traditionally associated with more rigid optical frames.

This material combination is particularly suitable for frames that require a clean molded appearance together with additional movement and structural support around the temples.

Appearance & Styling

The frame uses a relatively restrained square outline, but the layered color structure keeps it from appearing visually flat. A darker decorative layer can be paired with a lighter transparent or solid base, creating different levels of contrast across the front and temples.

The metal temple-end accent adds another material detail without changing the overall casual character of the frame. This makes the design suitable for collections positioned between basic everyday optical frames and more fashion-focused styles.

Lens Compatibility & Everyday Use

The frame is supplied with demo lenses and can be fitted with prescription lenses according to the required optical configuration. Its square proportions make it suitable for everyday prescription eyewear, office use, commuting, and casual styling.

The wire core spring temples also provide useful flexibility for regular wear, while the compact 51-18-140 mm format keeps the design visually neat rather than oversized.

Fit & Wearing Considerations

The 51 mm lens width, 18 mm bridge, and 140 mm temple length should be considered together when selecting the appropriate fit. A suitable frame is determined not only by face shape but also by facial width, bridge position, temple length, and the amount of lens coverage preferred.

The square silhouette creates a more defined outline around the eyes. It can work well for wearers who prefer a structured frame, while the relatively compact dimensions make it less visually dominant than oversized square styles.

Core Wire Temple vs. Rigid Plastic Temple

A conventional rigid plastic temple has a fixed structure with limited flexibility beyond the hinge area. A core wire temple adds an internal metal element that can support the temple structure and provide greater shaping flexibility.

For this model, the spring construction adds another level of movement at the temple. This makes the design particularly relevant to eyewear collections that emphasize a flexible wearing structure without moving to a fully metal frame.

Color & Customization

The transparent frame base provides a clean visual foundation for different color combinations. The decorative layer, temple color, metal accent, and other visible details can be coordinated to create different versions while preserving the same basic frame architecture.

OEM/ODM development can cover colors, logo application, packaging, and other product details. Customized versions can also be developed from physical samples or technical drawings, allowing the frame structure and appearance to be confirmed before formal production.

Production Process Behind the Temple Structure

The manufacturing process involves injection molding for the frame and CP temple components, together with the integration of the internal temple core and spring structure. Surface treatment and finishing are then carried out according to the selected appearance, followed by assembly and inspection.

Core wire processing is particularly important for this type of temple because the position and shape of the internal wire affect the temple's final structure and adjustment characteristics. The outer CP material must also maintain a consistent appearance after molding and finishing.

Development from Samples or Drawings

Existing samples or technical drawings can be used as the starting point for customized development. This is useful when adjustments are needed to frame proportions, temple construction, colors, branding details, or packaging.

Production Arrangement

Sample services are available for new development. The MOQ specified for this model is 100 pcs per color and 400 pcs per model, allowing different color combinations to be arranged within the production program.

Care & Maintenance Notes

Clean the frame regularly with suitable eyewear-cleaning materials and avoid placing it directly against hard or abrasive surfaces. When opening or closing the temples, use the normal range of movement of the spring mechanism instead of applying excessive force.

The internal wire core contributes to the temple structure, so unnecessary bending or repeated manual reshaping should be avoided. If the temple becomes loose or the spring mechanism develops unusual movement, professional adjustment is recommended.

Q&A

Q: What does “core wire temple” mean?

A: It refers to a temple with an internal wire structure inside the outer CP material. The wire supports the temple and allows additional shaping and flexibility compared with a simple rigid molded temple.

Q: Is the wire core visible from the outside?

A: The wire core is integrated inside the CP temple, so the main outer appearance remains molded and clean rather than exposing the internal reinforcement.

Q: What is the difference between the TR90 frame and CP temples?

A: TR90 is used for the front frame, while CP is used for the temples. The different materials allow the front and temple sections to be designed around their respective structural and processing requirements.

Q: What is the purpose of the spring mechanism in the temples?

A: The spring mechanism allows additional movement at the temple area when the glasses are opened and worn. It provides more flexibility than a completely fixed temple structure.

Q: Can the transparent frame color be changed?

A: Yes. The frame color is listed as customizable. Different color combinations can also be developed for the frame and decorative sections according to the final design.

Q: Can the metal detail at the temple end be customized?
