Custom Deep-Drawn Rectangular Enclosure

Single-Stage Deep Drawing & Precision Trimming Process

This custom deep-drawn rectangular enclosure demonstrates Runyuan’s advanced capabilities in precision metal forming and complex sheet metal manufacturing. Produced through a high-tonnage single-stage deep drawing process combined with precision trimming and punching, the component is engineered to achieve excellent dimensional stability and structural consistency.

Through optimized tooling design and controlled material flow, Runyuan effectively addresses common challenges in rectangular deep drawing, including sidewall deformation, corner cracking, uneven thinning, and bottom surface wrinkling.

Technical Profile & Manufacturing Solutions

Sidewall Stability Control – Preventing Deformation After Deep Drawing

During single-stage rectangular deep drawing, uneven material flow, tensile stress distribution, and springback effects can cause sidewall distortion after part release.

Runyuan’s engineering team optimizes die geometry, forming clearance, and material flow control to balance internal stresses throughout the drawing process. This ensures straight, rigid sidewalls with reliable dimensional accuracy for precise assembly requirements.

Reinforced Corner Forming – Preventing Cracking & Material Failure

The upper corner radius (R-angle) is one of the most critical areas during rectangular deep drawing, where concentrated tensile stress may lead to thinning or cracking.

By analyzing material behavior and optimizing blank design, punch radius, and die radius, Runyuan ensures smooth material transition into the forming cavity. This controlled forming process improves corner strength while maintaining consistent wall thickness and surface quality.

Bottom Surface Optimization – Achieving Smooth, Wrinkle-Free Forming

A successful deep draw requires precise control of material retention and compression forces. Excessive material flow into corner areas can result in wrinkles or uneven surfaces.

Runyuan utilizes optimized blank holder force settings, controlled press parameters, and precision-machined tooling clearances to minimize material accumulation and achieve a smooth, uniform bottom surface.

Precision Trimming & Integrated Punching – Ready for Final Assembly

After the deep drawing operation, the enclosure undergoes automated precision trimming and punching processes to achieve accurate dimensions and clean edges.

Advanced tooling control ensures burr-minimized cutouts, accurate hole positions, and consistent part geometry, making the enclosure suitable for downstream applications such as electronic housings, industrial equipment covers, and mechanical assemblies.
