Deep drawn stainless steel parts are seamless, cup-shaped or cylindrical components formed by progressively drawing flat sheet metal blanks into a die cavity through one or more tooling stages. Manufactured on single-action and multi-stage transfer presses from SS 304 and SS 316 sheet, deep drawn parts eliminate weld seams that would otherwise create corrosion initiation points or leak paths, making the process the preferred method for producing seamless cans, housings, and shells in critical electrical and process applications.

Deep Drawn Cylindrical Cans & Canisters

Seamless SS cans and canisters from 10 mm to 200 mm diameter are deep drawn in single or multiple stages for filter canisters, aerosol cans, battery casings, and process equipment containers. The seamless side wall eliminates weld-related corrosion and leak risks common to rolled-and-welded cylinder construction.

Deep Drawn Motor & Sensor Housings

Cup-shaped SS housings for electric motor end shields, proximity sensor bodies, and encoder housings are deep drawn to precise internal diameters for bearing and sensor component fitment. Seamless construction provides consistent wall thickness for EMI shielding and mechanical strength in rotating equipment applications.

Deep Drawn Filter Housings & Canister Shells

Multi-stage deep drawn filter canister shells and housing cups are produced for hydraulic filters, fuel filters, and process filtration cartridges where internal pressure resistance and weld-free construction are essential for filtration system integrity and burst pressure ratings.

Deep Drawn Connector Bodies & Electrical Shells

Cylindrical and stepped-diameter SS shells for electrical connector bodies, cable gland shells, and terminal housings are deep drawn with precision internal and external diameters for threaded connections and gasket sealing surfaces in outdoor and hazardous-area electrical equipment.

Multi-Stage Deep Drawn Components

Complex parts requiring a high draw ratio (depth-to-diameter) are produced through multiple redraw stages with intermediate annealing to relieve work hardening between draws. Progressive transfer press tooling produces high-volume multi-stage parts with consistent wall thickness and dimensional repeatability.

Deep Drawn Battery Cans & Cell Casings

Precision-drawn SS battery cans and cell casings for industrial battery packs and specialty cell applications are produced to tight internal diameter and wall thickness tolerances, critical for cell assembly automation and thermal management performance.

Custom Deep Drawn Parts to Drawing

Custom deep drawn components are produced to customer drawings and 3D models for OEM-specific housings, shells, and enclosures. Tooling is engineered for the specified draw ratio, wall thickness, and secondary features (flanges, piercings, threads) required by the application.

Deep Drawing Process Stages (Draw Ratio, Redraw, Ironing)

The limiting draw ratio (blank diameter to punch diameter) for SS 304/316 is typically 1.8–2.1 per draw stage before redrawing is required. Redrawing progressively reduces diameter and increases depth across multiple die stations, while ironing controls final wall thickness by controlled clearance reduction between punch and die.

Material Selection: SS 304 vs SS 316 for Deep Drawing

SS 304 offers excellent deep-drawing formability with high elongation and moderate work-hardening rate, suited to general housings and cans. SS 316 provides superior corrosion resistance for filter housings, chemical process cans, and marine electrical enclosures, though its higher work-hardening rate requires more conservative draw ratios and additional annealing stages.

Wall Thickness Control & Thinning

Deep drawing inherently thins the sidewall relative to the blank thickness, most pronounced at the punch radius transition. Process simulation and controlled blank holder pressure minimize excessive thinning, ensuring the finished part meets minimum wall thickness requirements for pressure-retaining or structural applications.

Surface Finish for Deep Drawn Parts

Deep drawn parts are supplied in mill finish, bright annealed, or polished finish as required. Internal surface finish is particularly important for filter housings and battery cans where smooth surfaces reduce particulate entrapment and improve assembly consistency.

Dimensional Tolerances in Multi-Stage Drawing

Progressive transfer tooling maintains diameter tolerances of ±0.05 mm to ±0.15 mm and depth tolerances of ±0.1 mm to ±0.3 mm depending on part size and draw stage count. Dimensional stability is verified through SPC sampling during production runs.

Secondary Operations (Trimming, Piercing, Flanging)

Deep drawn parts typically require trimming to final height, piercing of mounting or ventilation holes, and flanging or curling of the open end for assembly or gasket retention. These secondary operations are performed in-die on progressive tooling or as separate finishing operations for lower-volume parts.

Manufacturing Process

SS coil is blanked into circular discs sized for the target draw ratio, then drawn through the first die stage on a hydraulic or mechanical press with controlled blank holder pressure to prevent wrinkling. Parts requiring greater depth are progressively redrawn through additional die stations with intermediate process annealing to restore ductility lost to work hardening. Finished parts are trimmed to length, pierced or flanged as required, cleaned, passivated, and dimensionally inspected before packing. Heat number traceability is maintained from coil to finished batch.

Frequently Asked Questions

What is the maximum draw ratio achievable in a single stage?
SS 304/316 typically achieves a limiting draw ratio of 1.8–2.1:1 per stage; greater depths require redrawing through multiple stages.

Why choose deep drawn parts over welded cylindrical parts?
Deep drawn parts are seamless, eliminating weld-related corrosion initiation points and leak paths, and offer more consistent wall strength than rolled-and-welded construction.

Which grade is recommended for filter housings?
SS 316 is recommended for filter housings and process cans requiring chemical or chloride resistance; SS 304 is suitable for general indoor applications.

Can you manufacture custom deep drawn parts to drawing?
Yes. Custom tooling is engineered to customer drawings or 3D models for OEM-specific housings, shells, and enclosures.

What diameter and depth ranges can you produce?
Standard capability covers 10 mm to 200 mm diameter; larger and deeper parts are evaluated on a project basis.

Do you provide wall thickness certification?
Yes. Wall thickness and dimensional inspection reports along with EN 10204 3.1 Mill Test Certificates are supplied with every order.
