Deep Drawn Metal Oil Pan / Tray

Serving as a bottom protective carrier for powertrain or energy storage systems, this rectangular deep-drawn structure forms a sealed containment space in a single成型 operation. The perimeter flange features evenly distributed circular mounting holes for bolted connection to the main housing. Large radius transitions at the side wall corners effectively disperse stress concentration, preventing cracking under long-term vibration conditions.

The internal base plate is designed with three parallel transverse stiffening ribs (embossments). This structural feature significantly enhances the bending stiffness of the thin-walled sheet over large spans and optimizes bottom flatness to avoid assembly interference. The manufacturing process strictly controls material thinning rates and springback deformation caused by deep drawing, ensuring flange flatness meets sealing requirements while maintaining precise relative positioning of mounting holes for automated assembly.

Leveraging Suzhou Shuangyue Precision Sheet Metal's IATF 16949 quality management system, our factory is equipped with multiple hydraulic stretching presses and 3D laser cutting equipment. We can handle the delivery of aluminum or stainless steel structural components from prototype verification to small-batch trial production. Combined with inspection methods such as blue light scanners and CMMs, we accurately verify the profile tolerance of complex surfaces and key mounting hole positions. We also provide surface treatment services including anodizing, powder coating, or electroplating to meet the stringent appearance, corrosion resistance, and dimensional consistency standards of the automotive and new energy industries.
