LINDBERG

Brand Introduction: Founded in 1983, it is renowned for designing the world's first titanium rimless eyewear frame.
Hinge Features: The patented spiral hinge design is its classic signature, doing away with screws, rivets, and other traditional welding parts. For example, the original hinge system used in the air titanium and air titanium rim series has been in use ever since. The spirit titanium rimless series, with its spiral hinge, boasts far greater stability than ordinary rimless frames. The striptitanium series, thintanium series, Buffalo titanium series, and the famous item 9704, etc., adopt hinges with a simple design that blend well with the overall modernist style. The hinges of the n.o.w. titanium series make the connection between titanium and acetate seamless. However, due to the pursuit of ultimate lightness, the connection part is small, and one needs to be careful when wearing it. The simplified dot hinge design of the thintanium ultra-thin titanium series reflects minimalism.

KLENZE & BAUM

Brand Introduction: A cutting-edge brand from Munich, Germany, specializing in producing customized 3D printed frames.
Hinge Features: It has an original patented spherical hinge that is convenient, easy to disassemble, and durable. If the connection of the frame is under excessive force or the glasses are over-stretched, it can pop out to prevent the glasses from being damaged. Users can simply snap it back together within seconds, making it very easy to replace the temples.

MARKUS T

Brand Introduction: Founded in Germany in 1999, it was created by the young German designer and founder, Markus Temming.
Hinge Features: It is famous for its globally unique screwless rotating hinge structure, which has no redundant parts, being perfectly lightweight, low-key, and elegant. For example, the DOT MONO series features the iconic dot formed by the dot-shaped hinge, making the horizontally flipping temples blend functionality and modern aesthetics perfectly. The DOT NEO FIT titanium infinity series, with a full titanium frame matched with the DOT MONO structure, has temples that are only 0.6MM wide from the side view, presenting extremely delicate lines.

999.9

Brand Introduction: A leading brand in the sales of high-end handmade eyewear in Japan, it is extremely persistent about wearing comfort.
Hinge Features: It has developed various patented hinges such as "Inverse R", "S", "Bellows", and "Balance". These hinges can improve the force balance of the glasses, ensure the horizontal viewing angle of the lenses, keep the temples flexible and elastic when opening and closing, withstand greater tensile force at the same time, easily bear the weight of high-index lenses, and will not deform after long-term use.

OBE

Brand Introduction: A well-known German eyewear hinge brand, it is a top-notch hardware manufacturer. It enjoys a high reputation in the eyewear industry and is often regarded as a representative of high-quality hinges, just as iconic as the YKK zipper in the clothing industry.
Hinge Features:

• High Durability: Its products undergo strict quality control and testing. For example, the OBE hinge on the Tianbolai smart audio glasses has passed the violent opening and closing test for 10,000 times, while the national standard only requires 3,000 times. It can withstand frequent use for a long time and is not prone to problems such as damage and deformation.
• Excellent Elasticity: It adopts a double-core spring design, which endows the glasses with smooth and natural elasticity when opening and closing. The operation of opening and closing the temples feels comfortable, and it can effectively buffer external impacts, reducing damage to the frame. It also brings a better user experience to the wearer. For example, one can feel a soft and even rebound force when opening and closing the glasses.
• Exquisite Craftsmanship: It reflects the rigor and fineness of German manufacturing. Every link from material selection to production and processing is strictly controlled to ensure that the product quality and performance meet high standards. This makes the connection between the hinge and the frame and temples tight and stable, and the appearance is also relatively delicate, which can enhance the overall texture of the glasses.
  

Visottica Group

Brand Introduction: A well-known Italian eyewear accessory supplier.
Hinge Features:

• Innovative Design: For example, the 2D Hinge has a unique two-dimensional motion design. Through a patented solution, in addition to realizing the opening and closing of the temples, it also allows the temples to move up and down. Compared with traditional elastic hinges, this design greatly improves the bending resistance.
• Excellent Compatibility: Its WA Flex Hinge series is specially designed for frames made of materials such as wood, aluminum, titanium, and carbon fiber. It is suitable for frames that cannot undergo conventional soaking and welding operations. It can blend well with temples and frames of various materials, without affecting the overall design of the glasses, and can be laser-customized as needed.
• Reliable Quality: Take the WA Flex Hinge as an example. It has passed strict tests and has good strength performance. For example, the bending test can reach ±15° cycle 30 times, the tensile resistance is 250N, the additional opening force is 50N, and the opening and closing test can reach 40,000 times, demonstrating a high degree of durability.
• Convenient Installation: The Oreplus series hinge has a patented easy-twist system, which is convenient for the assembly of the front part of the frame, reducing production time and cost, and also simplifying the after-sales maintenance process. Moreover, there are 4 different sizes to choose from, equipped with soft and hard springs to adapt to different application scenarios, and it is easy to weld to the temples and wire core.
