Stamping is a high-precision metal forming process that uses dies and stamping presses to transform flat metal sheets or coils into desired shapes and components. This manufacturing method is widely recognized for its efficiency, consistency, and ability to produce complex geometries at high volumes.
Our stamping products are engineered to meet the rigorous demands of various industries, including automotive, electronics, aerospace, medical devices, and home appliances. By utilizing advanced press technologies and high-quality tooling, we deliver parts that excel in dimensional accuracy, surface finish, and structural integrity.
| Characteristic | Description |
| Process Definition | A cold-forming method that uses a press and die to cut or shape sheet metal by separating material along a predetermined contour1. |
| Common Operations | Includes punching (creating holes), blanking (cutting out parts), piercing (tearing holes without slugs), and shearing (straight-line cutting)2. |
| Material Thickness | Typically applied to materials thinner than 6.35mm (referred to as "sheet"), with thicker materials classified as "plate"3. |
| Design Considerations | Avoid sharp external/internal corners (R ≥ 0.5T, R ≥ 0.8mm) for safety and mold durability1. Minimize narrow slots/arms (depth/width ≥ 1.5T) to strengthen die edges2. |
| Material Types | Common materials include SPCC (cold-rolled steel), SECC (electro-galvanized steel), SGCC (hot-dip galvanized steel), and stainless steels (e.g., SUS301, SUS304)4. |
| Equipment | Involves presses, dies, CNC punching machines, laser/plasma cutters, and bending machines45. |
| Advantages | Enables high-volume production, cost efficiency, and complex geometries while maintaining material strength45. |
| Aluminum | AL5052, AL6061, AL6063,AL7075 etc. |
| Stainless steel | SS201, SS303, SS304, SS316 etc |
| Brass | C36000 (C26800), C37700 (HPb59), C38500 (HPb58), C27200 (CuZn37), C28000 (CuZn40) etc |
| Bronze | C51000, C52100, C54400, etc. |
| Iron | 1213, 12L14, 1215 etc |
| Steel | Q235, 20#, 45# etc. |
Q1: What are stamping parts?
A: Stamping parts are metal components manufactured through a stamping process, where flat sheet metal is placed into a stamping press and formed into specific shapes using a die and high pressure. This process is widely used for high-volume production of precise and durable parts.
Q2: What are the advantages of stamping parts?
A: The key benefits include:
High production efficiency and speed
Low per-unit cost for large volumes
Excellent repeatability and tight tolerances
Ability to create complex shapes and features
Good material strength and durability
Q3: What industries use stamping parts?
A: Stamping parts are essential in automotive, electronics, appliances, aerospace, medical devices, construction, and consumer goods industries.
Q4: What is the basic stamping process?
A: The basic process involves:
Feeding sheet metal into a stamping press
Using dies to cut, bend, or form the material
Ejecting the finished part
Secondary operations (if needed) like welding, assembly, or finishing
Q5: What metals can be stamped?
A: Commonly stamped materials include:
Cold rolled steel (CRS)
Hot rolled steel (HRS)
Stainless steel (SS)
Aluminum alloys
Copper and brass
Pre-plated or coated metals
Q6: What is the difference between progressive die stamping and compound die stamping?
A:
Progressive Die Stamping: Metal strip moves through multiple stations in one die, producing a complete part with each press stroke
Compound Die Stamping: Performs multiple operations (cutting, forming) in a single press stroke at one station
Transfer Die Stamping: Parts are mechanically moved between different dies in a press line
Q7: What are important design considerations for stamping parts?
A: Key factors include:
Material selection and thickness
Bend radii (minimum recommended: 1x material thickness)
Hole and slot sizes (minimum diameter: 1.2x material thickness)
Tolerance requirements
Part complexity and tooling feasibility
Burr direction specifications
Q8: What are typical tolerances for stamped parts?
A: Standard tolerances are typically ±0.1mm to ±0.25mm (±0.004" to ±0.010"), depending on material, thickness, and part complexity. Tighter tolerances are possible but increase cost.
Q9: How do I minimize costs in stamping part design?
A: To optimize costs:
Use standard materials and thicknesses
Design for manufacturability
Specify realistic tolerances
Minimize secondary operations
Consider tooling complexity during design
Q10: What is tooling/die cost?
A: Tooling cost is the one-time expense for designing and manufacturing the specialized dies used in stamping. While initial costs can be significant, they are amortized over production volumes, making per-part costs very economical for large runs.
Q11: How long does tooling take to manufacture?
A: Tooling lead times typically range from 4-12 weeks, depending on:
Die complexity
Part size and precision requirements
Material specifications
Current workload
Q12: Can I get prototypes before mass production?
A: Yes, several options exist:
Soft Tooling: Quick, lower-cost tooling for prototype quantities
Laser Cutting & Forming: For very low volumes
3D Printed Prototypes: For form and fit checking
Samples from Production Tooling: First articles for final approval
Q13: What is the minimum order quantity (MOQ)?
A: MOQs vary by manufacturer but typically start at 10,000+ pieces for standard stamping due to tooling costs. Lower quantities may be available with surcharges or using different production methods.
Q14: What finishing options are available?
A: Common finishing processes include:
Plating: Zinc, nickel, chrome, or tin
Painting & Powder Coating
Anodizing (for aluminum)
Deburring & Tumbling
Heat Treatment
Silk Screening & Laser Marking
Q15: What quality control measures are implemented?
A: Standard QC includes:
First Article Inspection (FAI)
In-process inspections
Statistical Process Control (SPC)
Final audit before shipment
Material certifications
Dimensional verification with CMM
Q16: What certifications do stamping manufacturers typically hold?
A: Common certifications include:
ISO 9001:2015 Quality Management
IATF 16949 (for automotive)
ISO 14001 Environmental Management
RoHS/REACH compliance
Q17: What information is needed for a quotation?
A: Please provide:
Detailed drawings (2D/3D CAD files)
Material specifications
Annual volume requirements
Surface finish requirements
Special packaging needs
Quality standards
Q18: What file formats are preferred for part designs?
A: Preferred formats include:

2D: DWG, DXF, PDF (with complete dimensions)
Q19: Can you help with design optimization?
A: Yes, our engineering team provides Design for Manufacturability (DFM) feedback to optimize your design for stamping, reduce costs, and improve quality.
