TR90 Aluminum Alloy Hollow Temple Glasses

When planning optical frame procurement, Hongtu Eyewear supplies the TR90 Aluminum Alloy Hollow Temple Glasses in a 56-14-140 mm unisex size with demo or prescription lens options. The temples use precision-cut perforations to reduce material weight and add a distinctive geometric detail, while the TR90 front keeps the overall frame lightweight and flexible for everyday optical use.

Product Specifications

Product Characteristics

1. Perforated Aluminum Alloy Temples

The defining feature of TR90 Aluminum Alloy Hollow Temple Glasses is the hollow aluminum alloy temple structure. Geometric perforations are cut through the middle section of the temples to remove excess material while retaining the main support structure of the aluminum alloy. The open pattern also creates a visible metallic detail that adds depth to the side profile.

2. Lightweight 18–22 g Frame

The combination of a TR90 front and perforated aluminum alloy temples keeps the frame weight at approximately 18–22 g excluding lenses. Based on the supplied product data, this is about 30% lighter than full-metal glasses with equivalent specifications, making weight reduction a central design characteristic of the model.

3. TR90 Front Frame

The front frame is made from TR90, providing a lightweight polymer structure for the square optical shape. The material complements the aluminum alloy temples by reducing the amount of metal used across the overall frame construction.

4. Square Optical Profile

The front uses a structured square silhouette with clean lines suited to business and professional optical collections. The relatively restrained front design also allows the perforated temples to become the main visual detail of the frame.

5. Multiple Prescription Lens Options

The frame is available with demo lenses or prescription lenses and supports common optical configurations including myopic lenses, blue-light-blocking lenses, and photochromic lenses. Final lens specifications can be selected according to the required optical configuration.

Hollow Temple Design: Function and Appearance

The perforated temple structure serves both a functional and visual purpose. Removing material from the central temple section helps lower the weight contributed by the aluminum alloy, while the geometric openings create a recognizable side profile under different lighting conditions.

Instead of using a solid metal temple throughout its length, this design combines an open aluminum alloy structure with a TR90 front. The result is a mixed-material construction that keeps the frame visually structured without relying entirely on a full-metal frame.

Size and Lens Configuration

The frame measures 56-14-140 mm, referring to a 56 mm lens width, 14 mm bridge width, and 140 mm temple length. These dimensions provide a useful reference for optical frame selection and lens fitting.

The square shape is commonly considered for round, square, and oval face shapes, but the actual fit depends on facial width, bridge position, temple length, and individual wearing preference. For prescription applications, lens type and optical parameters should be confirmed before production.

Applications

The TR90 Aluminum Alloy Hollow Temple Glasses are designed for optical collections that require a lightweight frame with a structured square front and more distinctive temple detailing. The combination of TR90 and aluminum alloy makes the model suitable for business eyewear, office use, professional commuting, and general everyday prescription applications.

The perforated metal temples also make the model suitable for collections looking for a more technical or contemporary visual element without changing the overall square frame profile.

Lens Options

The frame can be supplied with demo lenses for display or fitted with prescription lenses. Available lens configurations include myopic lenses, blue-light-blocking lenses, and photochromic lenses, subject to the final lens requirements.

For prescription production, the required optical parameters should be confirmed before processing to ensure the lens specification matches the intended application.

Factory Capabilities

About Hongtu Eyewear

Our factory is located in Taizhou, China and has more than 15 years of experience in the research, development, and production of eyeglass frames. The factory operates three production lines with standardized workshops and quality inspections covering key production stages from incoming materials to finished assembly.

The production range includes TR90, CP, and PC injection-molded frames, together with metal eyewear, sunglasses, and children's glasses. For mixed-material designs such as Model YD251015, the available production processes support both molded frame components and aluminum temple structures.

Production Process and Quality Control

The production workflow covers raw material inspection, injection molding, surface treatment, component assembly, and finished-product inspection. TR90 production can involve CP pin injection molding, TR90 injection molding, and insert injection molding, while dedicated surface-treatment equipment supports effects such as gradient colors and multi-color spot coatings.

Quality inspections are performed throughout the production process to help maintain consistent appearance, assembly, and batch quality. For this model, the production system is applied to the TR90 front, aluminum alloy temple components, surface treatment, and final assembly.

OEM/ODM Customization

Hongtu Eyewear supports OEM/ODM customization for applicable logo, color, lens, and packaging requirements. Customized development can be discussed based on samples, drawings, or brand specifications.

The standard MOQ is 100 pcs per color and 400 pcs per model. Specific requirements for customized colors, logos, lenses, or packaging should be confirmed before production.

Quote and Sample Support

Hongtu Eyewear aims to provide a detailed quotation within 24 hours after receiving an inquiry. Samples are available with a sampling fee based on the actual design and quantity requirements. Once production is confirmed, the sample fee can be refunded or deducted from the order amount according to the agreed arrangement.

Use and Care Notes

Clean the lenses and frame with suitable eyewear-cleaning materials and avoid abrasive cloths or surfaces that may scratch the lenses or finish. When opening or closing the temples, use the normal hinge movement and avoid excessive force on the aluminum alloy sections.

For long-term use, periodic inspection of the temple connection and frame assembly can help identify looseness or other visible changes at an early stage.
