Product Overview – Stainless Steel Stamping & Stamped Parts

Stainless steel stamped parts are formed by applying compressive force through hardened tool steel dies to SS sheet or coil stock, permanently deforming the material into the required shape without removing metal. Stamping processes are classified as blanking (cutting), forming (bending/drawing), and combining operations. The process delivers high dimensional repeatability at production rates from hundreds to millions of parts per shift, making it the most cost-effective metal forming method for volume SS component manufacture.

Progressive Die Stamped Components

Progressive die stamping simultaneously performs multiple operations — blanking, piercing, bending, embossing, coining — in a single die set across a strip of SS sheet. Suitable for complex 2D and shallow 3D parts with tight tolerances. Applications include SS terminal brackets, contact clips, spring contacts, bus bar connection plates, relay housings, switchgear mounting clips, shielding plates, and chassis bracket sets for electrical OEM assemblies. Tolerances achievable: ±0.05 mm on critical dimensions.

Deep Drawn Stainless Steel Parts

Deep drawing converts flat SS sheet blanks into hollow cups, cylinders, boxes, cones, and complex enclosure forms through progressive die stages. Used for manufacturing SS sensor housings, instrument enclosures, food-grade containers, pressure vessel end caps, aerosol can bodies, automotive fuel filter housings, and medical instrument cups. Material draw ratios up to 2.2:1 achievable in austenitic SS 304/316. Wall thickness control and surface finish quality are critical deliverables in deep drawn SS parts.

Blanked & Pierced SS Components

Precision blanked SS discs, rings, washers, gaskets, shims, plates, and perforated components are produced from SS 304/316/430 coil on high-speed mechanical presses. Blanking tolerances of ±0.1 mm are standard; fine blanking achieves ±0.02 mm on critical shear-edge components. Used for SS washers, valve seat discs, orifice plates, shim sets, disc springs, diaphragm blanks, and filter element discs.

Coined & Embossed SS Parts

Coining and embossing operations in SS produce raised lettering, logos, dimensional datum features, stiffening ribs, identification marks, and precise thickness control on critical areas. Used for SS name plates, electrical enclosure identification panels, calibration shims, precision distance pieces, and decorative architectural SS components requiring defined surface relief patterns.

Multi-Stage Compound Die & Transfer Press Parts

Complex 3D SS stampings requiring multiple forming stages are produced on transfer press lines where blank parts are automatically transferred between stations. Applications include automotive exhaust flanges, heat shield stampings, structural brackets, large-format deep-drawn trays, and electrical panel chassis parts. Transfer press capability up to 400-ton press force for heavy-gauge SS components.

Post-Stamping Operations & Secondary Processes

In-house secondary operations include deburring (tumble/vibratory/manual), TIG and spot welding, resistance welding, tapping, thread insertion (PEM nuts, rivet nuts), passivation, electropolishing, laser marking, and assembly. These value-added services allow supply of complete sub-assemblies rather than loose stampings, simplifying customer supply chains and reducing inbound handling costs.

Precision Tooling & Dimensional Repeatability

All stamping tooling is designed and manufactured in-house using CAD/CAM and CNC machining of D2, DC53, and carbide punch/die steel. Tool life extends to 2–5 million strokes per maintenance interval on SS stampings. Progressive die sets include misfeeding detection sensors, die protection systems, and automatic strip lubrication for uninterrupted high-speed production. First-article approval drawing review available for OEM qualification processes.

Material Utilisation & Scrap Optimisation

Strip nesting software optimises blank layout in progressive dies, achieving 75–90% material utilisation rates on SS strip. Skeleton scrap is segregated by grade and sold as SS scrap at current market rates, reducing effective raw material cost. Material certification traceability from coil to finished part is maintained for aerospace and medical OEM customers requiring full material genealogy.

Surface Finish for Stamped SS Parts

Deep-drawn and formed SS parts retain their original 2B or BA mill finish on unexposed surfaces. Visible surfaces can be maintained at No.4 brushed or No.8 mirror finish using in-house polishing. Passivation per ASTM A967 improves the natural oxide layer for improved corrosion resistance. Electropolishing per ASTM B912 provides ultra-clean, low-Ra surfaces for pharmaceutical and biotech applications.

OEM Part Approval & Documentation

PPAP (Production Part Approval Process) level 1–3 documentation is available for automotive OEM customers. FAI (First Article Inspection) per AS9102 for aerospace and defence. Material Test Reports (MTR) per EN 10204 2.2 or 3.1 available. IMDS submission capability for automotive material data reporting. CMM measurement reports for critical-dimension stampings.

Food-Grade & Medical SS Stampings

SS 316L stampings for medical devices, pharmaceutical equipment, and food contact applications are manufactured under enhanced cleanliness protocols. No cutting oils with chlorinated additives, no carbon steel tooling contact, passivation to ASTM A967, and Ra surface measurement reports accompany each lot. Suitable for FDA 21 CFR and EU 10/2011 food-contact material compliance.

Manufacturing Process

SS coil is received with mill test certificates and slit to required strip widths in-house. Strip is fed into progressive die sets on mechanical or hydraulic presses. Progressive stations perform blanking, piercing, notching, forming, coining, and cut-off operations sequentially. Deep draw parts undergo multi-stage redrawing with intermediate annealing for high draw ratios. Post-stamping operations include deburring, vibratory finishing, TIG/spot welding, tapping, passivation, and electropolishing as required. CMM inspection of first articles and statistical sampling of production batches ensures dimensional conformance. Traceability records link each finished batch to the originating SS coil heat number.
