Deep Drawn Metal Pressing Component

A deep drawn metal pressing component is a seamless shell formed by pulling flat sheet into a die under controlled draw ratios, producing cups, housings, covers and pockets without a welded seam. It is produced from DC03 deep-drawing cold-rolled steel, SUS304 or 6061 aluminum, with the grade selected for its draw ductility against the required depth. Stock thickness runs 0.5-4.0 mm across a 0.3-5.0 mm range, and the part is formed to keep the draw radius at least equal to sheet thickness so corners draw without cracking or splitting. Three-dimensional outer dimensions are held to +/-0.15 mm while inner cavity fit is tightened to +/-0.1 mm for precision assembly, and post-processing options include brushing, anodizing, powder coating or electroplating for the required appearance and corrosion level. The process covers irregular shells, brackets and cavities that would otherwise need multiple welded pieces, and tooling is built directly from the customer's 3D drawing or a physical sample. The process covers irregular shells, brackets and cavities that would otherwise need several welded pieces, and a physical sample can be reverse-modeled into a forming die when no CAD data is available.

The key purchase risk in deep drawing is split walls or uneven thinning when depth outruns the material's ductility. Because we select draw-grade strip per part and confirm geometry on a sample from the customer's 3D data, the draw radius, blank holder and deep-draw sequence are tuned to the actual shell depth - turning a part that could crack on the first hit into a repeatable formed component with stable wall thickness.
