| 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:
3D: STEP, IGES, SolidWorks, CATIA
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.
