Chanxan Laser Provided Laser Engraving Equipment for the Beijing 2022 Winter Olympic Torch

The Beijing 2022 Winter Olympic torch, named "Flying" (飞扬), became one of the most iconic industrial designs of the Games. Officially unveiled by the Beijing 2022 Organizing Committee, the torch combines traditional Chinese aesthetics with advanced engineering technology. Its spiraling ribbon structure symbolizes the fusion of ice and fire, while the carbon-fiber body delivers lightweight strength and high-temperature resistance.

Behind the elegant appearance of the torch stood a series of highly demanding manufacturing processes. Among them, the precision laser engraving of the handle's snowflake texture and decorative patterns represented a major technical challenge due to the torch's asymmetrical conical geometry and carbon-fiber material characteristics.

As a laser engraving equipment provider for both the Beijing 2022 Winter Olympic Torch and Winter Paralympic Torch projects, Chanxan Laser successfully developed an asymmetric laser defocusing 3D engraving solution to achieve high-precision rotating marking on the torch surface. This project demonstrated the company's advanced customization capability, engineering innovation, and reliability in supporting national-level projects.

Challenge: High-Precision Engraving on an Asymmetrical Conical Surface

The Beijing 2022 torch adopted a complex tapered spiral structure rather than a standard cylindrical body. The surface continuously changes in curvature and focal distance during rotation, making conventional rotary laser marking methods unsuitable.

Several key technical difficulties had to be overcome:

· Asymmetrical conical geometry created unstable focal positioning during engraving.

· Carbon-fiber composite material required precise energy control to avoid thermal damage, discoloration, or surface delamination.

· The handle's snowflake and decorative textures demanded extremely high consistency and clarity over a continuously curved surface.

· The torch's premium aesthetic standards required flawless visual uniformity without distortion or overlap.

Traditional 2D rotary marking systems could not maintain stable laser focus across the varying surface heights of the torch. Even slight focal deviations would lead to inconsistent engraving depth, blurred textures, or visible defects. At the same time, the project carried national-event quality requirements and strict supplier evaluation standards, demanding both engineering reliability and process repeatability.

Chanxan Laser Solution: Asymmetric Laser Defocusing 3D Engraving Technology

To solve the engraving challenges of the Winter Olympic torch, Chanxan Laser independently developed an asymmetric laser defocusing 3D engraving technology specifically designed for rotating marking on irregular conical surfaces.

The customized solution integrated a two-dimensional manual slide table, a servo rotary axis, an electric lifting mechanism, a fiber laser system, and an air-blowing and smoke-extraction module to support stable engraving on the torch's asymmetrical conical surface.

The servo rotary axis enabled synchronized rotation of the torch body during processing, while the electric lifting structure adjusted focal height according to the continuously changing surface geometry. Combined with the two-dimensional manual slide table, the system achieved accurate positioning and stable marking alignment across the tapered carbon-fiber surface.

The fiber laser system delivered high-precision engraving of the torch's snowflake textures and decorative patterns with excellent clarity and consistency. Meanwhile, the integrated air-blowing and smoke-extraction system effectively removed processing residues and minimized thermal effects, helping preserve the integrity and appearance of the carbon-fiber material.

The technology successfully achieved:

· Uniform engraving depth

· Clear and consistent micro-pattern rendering

· Stable processing on asymmetrical tapered surfaces

· Reliable repeatability for batch production

· Clean non-contact processing with minimal thermal impact

This project further demonstrated Chanxan Laser's capability to rapidly develop customized laser solutions for highly complex industrial applications rather than relying solely on standardized equipment platforms.

As official information from Beijing 2022 noted, the torch design emphasized the integration of "sports, culture, art, and science," while advanced industrial technologies played a critical role in bringing the design into production reality.

Significance of the Project

The successful implementation of the Beijing Winter Olympic torch engraving project carried significance far beyond a single manufacturing application.

First, it demonstrated that Chinese laser equipment manufacturers could support highly complex, internationally visible projects requiring exceptional quality standards and process stability.

Second, the project validated Chanxan Laser's technical capabilities in advanced 3D laser processing, particularly for irregular surfaces and high-value composite materials. The ability to engrave intricate textures on asymmetrical rotating components represents an important breakthrough for precision laser manufacturing.

Third, the project reflected Chanxan Laser's strengths in:

· Customized solution development

· Independent R&D capability

· Engineering problem-solving

· Precision automation integration

· Stable delivery for high-standard applications

The successful selection as a Winter Olympic and Winter Paralympic torch laser engraving equipment provider also demonstrated that Chanxan Laser met the stringent supplier qualification and quality screening standards associated with national-level projects.

Beyond the Olympic torch itself, the underlying technology has broad application potential in industries requiring high-precision surface processing on complex geometries, including:

· Aerospace components

· Medical devices

· Automotive interiors

· Consumer electronics

· Premium industrial products

· Carbon-fiber composite processing

Conclusion

The Beijing 2022 Winter Olympic torch project represented both a technological challenge and a symbol of advanced manufacturing capability. Through the development of asymmetric laser defocusing 3D engraving technology, Chanxan Laser successfully solved the complex problem of precision rotating engraving on asymmetrical conical carbon-fiber surfaces.

As a laser engraving equipment provider for both the Beijing Winter Olympic Torch and Winter Paralympic Torch, Chanxan Laser demonstrated its ability to combine innovation, customization, and engineering precision under the demanding standards of a world-class event.

Driven by a consistent commitment to customer-oriented innovation, Chanxan Laser continues to focus on solving complex industrial laser processing challenges with reliable and customized solutions — transforming difficult manufacturing requirements into achievable production results.
