Advanced Forming Process by Stamping for Complex Design

The unique design of this mudguard requires precision during the forming process to prevent deformation, especially along its complex contours. By utilizing the latest stamping techniques, we ensure each part's design and shape adhere to the exact specifications. We use custom checking fixtures to inspect the dimensions, especially profile of a surface and profile of a line, ensuring they meet all required tolerances.

Overcoming Return Edge Challenges

One of the toughest challenges is creating the return edge on the curved sections. This process is particularly demanding with aluminum alloy, which tends to crack under bending process. However, with our advanced methods, we have successfully mastered this difficult step, ensuring a durable and accurate return edge.

Superior finishing for appearance

We apply a comprehensive polishing process to achieve a smooth and flawless surface finish for this fender, meeting strict appearance standards for cosmetic parts applied on motorcycles. The component can then be treated with clear anodizing for corrosion resistance, or custom anodizing in various colors to meet specific design requirements.

Manufacturing Capabilities and Application Scope

Shih Yeh offers mature precision metal stamping capabilities for aluminum components with complex curves and contoured surfaces. During forming, strict control of profile of line and profile of surface is applied to ensure precise fit with vehicle structures and surrounding parts. Dedicated checking fixtures are used to verify key dimensions and profiles, supporting stable quality and consistent mass production.

Aluminum material selection enables effective lightweight design while maintaining sufficient structural strength, making it well suited for vehicle and outdoor applications. Surface treatments such as brushed finish, polishing, and anodizing are applied to enhance corrosion resistance, weather durability, and surface appearance, ensuring reliable performance under varying environmental conditions.

These stamping and surface treatment technologies are particularly well suited for motorcycle components as well as outdoor and mobility equipment applications. In motorcycle products such as mudguards, covers, guards, decorative metal parts, and luggage racks, components must balance structural strength, precise fit, and consistent visual appearance, placing clear requirements on stamping stability and surface quality.

For outdoor and mobile equipment, metal cosmetic or protective parts are often exposed to long-term use and changing environmental conditions, making durability and surface consistency essential. Based on customer drawings and application requirements, Shih Yeh provides optimized process planning to support reliable mass production while ensuring forming accuracy, surface performance, and long-term product consistency.
