Stamping often receives criticism in precision manufacturing, but a well-designed progressive die stamping operation delivers exceptional consistency across high volumes at speeds and costs unmatched by CNC machining.
Stamping excels at producing flat or mildly formed sheet metal parts with consistent features, while our hybrid approach combines stamping efficiency with CNC precision for critical features requiring tight tolerances.
Our stainless steel stamped brackets and mounting plates are manufactured using progressive die stamping presses (60-400 tons) handling material thicknesses from 0.3mm to 3.0mm in stainless steel 304, 316, and 430, with secondary CNC operations for precision.
Key Features
Progressive Die Efficiency: Multi-station progressive dies produce complete parts at 30-200 strokes per minute, offering significant cost savings at volume
Material Range: Stainless steel 304, 316, 430 in thicknesses from 0.3mm to 3.0mm, plus aluminum, copper, and brass for non-corrosive applications
Hybrid Precision: Stamped bulk shape combined with CNC secondary operations for features requiring ±0.01mm or tighter tolerances
Consistent Quality at Volume: Identical parts with no tool wear drift or operator variability once dies are qualified
Surface Treatment Options: Passivation, electropolishing, powder coating, and plating available for specific requirements
Rapid Prototyping Without Dies: Laser cut and CNC bent prototypes from the same sheet material for design validation before tooling investment
Die Design & Simulation: Progressive die design with forming simulation software to verify material flow and springback compensation
Volume Cost Advantage: 40-60% cost reduction compared to CNC machining at volumes of 10,000+ pieces
IATF 16949 Quality: Automotive-grade quality system with PPAP documentation, SPC monitoring, and full material traceability
Complete Surface Treatment: In-house passivation and coordination with certified plating and coating suppliers
Manufacturing Process
Design & Feasibility: Part review for stamping feasibility, material selection, formability analysis, and cost comparison
Prototype (Laser Cut): Laser cut and CNC bent prototypes from sheet stock for fast design validation without die investment
Die Fabrication: Progressive die design and manufacture with forming simulation optimization
Progressive Die Stamping: Production stamping on 60-400T presses with in-process inspection at defined intervals
CNC Secondary Operations: Precision drilling, reaming, tapping, deburring, and chamfering for tight-tolerance features
Surface Treatment & Packaging: Passivation, electropolishing, powder coating, or plating with protective packaging for shipment
Frequently Asked Questions
What is your minimum order quantity?
For laser cut prototypes, 100 pieces. For progressive die stamped production, 5,000 pieces minimum. We'll advise on the most cost-effective manufacturing method for your volume.
Can you make prototypes before building stamping dies?
Yes. We laser cut and CNC bend prototypes from the same sheet material and thickness. The prototype matches the final stamped part geometry for design validation.
What thickness can you stamp?
Standard range is 0.3mm to 3.0mm in stainless steel. Up to 6.0mm for simpler geometries on heavier tonnage presses.
How does stamped cost compare to CNC machining?
At low volumes (under 5,000), CNC or laser cutting is cheaper. At 10,000+ pieces, stamping is typically 40-60% less per piece. We'll provide a cost comparison for your specific part and quantity.
Can you add tapped holes to stamped parts?
Yes. CNC tapping after stamping is a standard secondary operation for us. We can also install PEM inserts, weld studs, and other threaded fasteners.
Do you provide IATF 16949 documentation?
Yes. PPAP, control plans, PFMEA, and SPC data for automotive qualification. Full material traceability on every production run.
