Fine Blanking on Thick Aluminum Alloy

The luggage rack is made from a 4mm-thick aluminum alloy, which presents a challenge due to the material's thickness. To create side slots and central slots without tearing cuts, we utilize fine blanking. This process requires precision to handle the thick material while ensuring clean, accurate cuts. Fine blanking allows for a precise finish that maintains the material's structural integrity while delivering a professional-quality result.

CNC Machining with Full Perimeter Chamfering

After fine blanking, the rack undergoes chamfering along its entire perimeter, smoothing out all edges. This process not only enhances the product's appearance but also ensures that all edges are safe to handle, eliminating any sharp corners. The smooth, rounded edges contribute to both the aesthetic and the practical function of the luggage rack.

Surface Treatment: Brushing and Anodizing

The final stage of production includes a meticulous surface treatment. We start by brushing the aluminum alloy in a specified direction, giving it a sleek, uniform finish. Afterward, the rack undergoes anodizing, a treatment that not only improves its corrosion resistance but also enhances the overall aesthetic. These finishing steps not only protect the product from environmental wear but also give it a premium look, ensuring long-lasting performance.

Manufacturing Capabilities and Application Scope

This type of luggage rack is a structural component that also serves an exterior function. It is commonly produced using thicker metal sheets, which tend to create noticeable tearing cuts during punching and cutting operations. These tearing cuts can affect edge quality, assembly accuracy, and overall structural reliability. Shih Yeh has extensive experience working with various metals and thick-plate stamping. Based on part geometry and application needs, we can apply fine blanking processes to effectively reduce tearing cuts, achieving cleaner edges and more consistent hole quality for stable mass production.

These manufacturing capabilities are well suited for components that must withstand load bearing, vibration, and long-term outdoor use, such as motorcycle luggage racks, support brackets, mounting bases, and structural parts for transportation equipment. In real operating environments, these components are exposed to continuous mechanical stress, cyclic motion, and environmental factors, which place clear demands on thick-plate stamping stability, edge quality control, assembly consistency, and long-term structural durability. For transportation industry applications that require reliable structural performance, Shih Yeh provides process planning and mass production support based on customer drawings and actual application conditions, ensuring consistent forming quality and stable production performance.
