Aluminum Alloy Deep Drawn Housing

This metal housing with deep cavity features is formed using an integral deep drawing process. The top design includes three parallel groove stiffeners, effectively enhancing the bending stiffness and compressive strength of the thin-walled structure. The flange extending from the bottom is equipped with multiple circular mounting holes for secure connection and positioning with the main equipment body. This integrated flanged structure is common in electronic or mechanical components that require both lightweight design and sealed protection.

The core of manufacturing such parts lies in controlling material flow and wall thickness uniformity during the drawing process to prevent cracking or wrinkling at the R-corners, while ensuring the flatness of the flange surface to meet assembly gap requirements. The top groove features are typically obtained through mold shaping or secondary stamping, which relies heavily on mold precision. Given the ductility of aluminum materials, springback-induced dimensional deviations must be strictly controlled during processing to ensure hole coordinates and outer contours comply with drawing tolerances, avoiding subsequent assembly interference.

Leveraging Suzhou Shuangyue Precision Sheet Metal's IATF16949 and ISO 9001 certified systems, our factory is equipped with multiple deep drawing hydraulic presses and CNC stamping equipment, capable of handling deliveries from prototype verification to small-batch trial production. Combined with blue light scanners and CMMs, we can accurately verify the profile of complex surfaces and key mounting hole positions. We support surface treatments such as anodizing and powder coating based on application scenarios, meeting the stringent standards for appearance, corrosion resistance, and structural strength required by automotive parts, new energy battery packs, and energy storage equipment.
