L-Shaped Metal Mounting Bracket

The L-shaped metal mounting bracket is formed through multiple precision bending processes, with the vertical plate and horizontal base arranged at specific angles. The side walls feature regularly spaced circular and slotted through-holes for secure component connection and position adjustment. This structural design is commonly used in load-bearing connection points, such as automotive seat frame supports or internal fixtures for new energy battery packs.

During manufacturing, strict control of springback coefficients across multiple bends is essential to ensure the parallelism and perpendicularity of the mounting surfaces meet drawing tolerances. Punching features on the flanges are formed using CNC turret punches or laser cutting with dies, effectively preventing edge burrs and ensuring consistent hole spacing. For structural parts with complex spatial angles, the factory utilizes CNC press brakes and 3D laser cutters to precisely control the relative positional accuracy of each plane.

Leveraging Suzhou Shuangyue Precision Sheet Metal's IATF 16949 certified system, we perform 100% inspection of key dimensions using blue light scanners and coordinate measuring machines (CMM) to ensure delivery quality meets the stringent standards of the automotive and energy storage industries. We support surface treatment options such as electrophoresis, powder coating, or galvanization based on operating conditions to enhance corrosion resistance. We also accommodate non-standard sheet metal requirements, ranging from prototype verification to small-batch trial production.
