Faster quoting
Clear tooling approach + process route in the first reply (die concept, stations, risks).
Better consistency
Controlled forming, burr direction, and critical features—built into the die, not “fixed later”.
Lower total cost
Right die for the job reduces secondary ops and rework across long production runs.
Finish-ready
Tooling accounts for plating/powder coat needs (racking, edges, masking constraints).
Surface Treatments for Custom Stamped Parts
Finishes impact corrosion resistance, appearance, electrical contact, paint adhesion, and assembly behavior. Selection should match the base material (carbon steel / stainless / aluminum), environment, and functional needs (e.g., conductivity, torque consistency, masking areas, post-weld cleaning).
Zinc Plating (Clear/Blue Passivation)
- Common choice for carbon steel stampings used in indoor or mild outdoor environments.
- Often paired with chromate conversion (e.g., clear/blue) for improved corrosion behavior.
- Good fit for brackets, clips, covers, and general assembly parts.
Our Metal Stampting Capabilities
Different stamping processes vary in forming principles, structural characteristics, and application scenarios. Selecting the appropriate process helps optimize performance, efficiency, and cost.
Blanking / Piercing Parts
The stamping process primarily involves shearing operations such as blanking and punching, which separate the metal material to obtain the desired shape or hole pattern. This process offers high production efficiency and good dimensional consistency, making it suitable for mass production.
Features: Low cost, high productivity, stable dimensions
Applications: Washers, connector plates, electrical contacts, mounting plates
Bending / Forming Parts
By bending, flanging, and ribbing, metal sheets are formed into specific three-dimensional structures while essentially maintaining the material thickness. This process is suitable for parts with high structural and assembly functional requirements.
Features: Flexible forming, diverse structures, wide applicability
Applications: Brackets, mounting parts, reinforcements, structural connectors
Deep Drawn Parts
The deep drawing process transforms flat sheet material into hollow or semi-hollow shapes with a certain depth. This process typically requires multiple steps and demands high material ductility and process stability.
Features: Deep forming capability, strong integrity, uniform walls
Applications: Metal housings, covers, containers, industrial enclosures
Progressive Stamping Parts
Progressive die stamping continuously performs multiple processes such as punching, forming, and trimming within the same die set, with automatic material feeding, making it suitable for high-precision, high-consistency mass production.
Features: High automation, high efficiency, excellent repeatability
Applications: Automotive parts, electronic hardware, precision stamped components
Combined Stamping Process Parts
Compound processes combine multiple processes such as blanking, forming, and deep drawing on the same part. This is suitable for stamping products with complex structures and high levels of functional integration, and requires extensive experience in mold design and manufacturing.
Features: High process integration, complex structures, tight tolerances
Applications: High-end industrial equipment parts, function-integrated metal components

Metal Stamping Applications: Case Studies
Automotive Bracket Manufacturing
A leading automotive supplier needed to produce 500,000 mounting brackets annually with strict tolerance requirements of ±0.1mm. By implementing progressive die stamping with in-die sensors for real-time quality control, we achieved:
- 35% reduction in production costs compared to previous machining process
- 99.8% first-pass yield rate
- Production rate of 2,000 parts per hour
- Material waste reduction of 42%
The high-strength steel brackets maintained consistent quality across production runs, meeting all automotive industry standards.
Medical Device Component Production
A medical device manufacturer required precision stainless steel components for a surgical instrument. Using deep draw stamping with specialized tooling, we delivered:
- Components with tolerances of ±0.025mm
- Surface finish of 0.4 Ra or better
- 100% compliance with FDA material requirements
- Elimination of secondary finishing operations
The seamless, burr-free components significantly reduced assembly time and improved device reliability.

FAQS
What information is required to get an accurate quote for custom metal stamping parts?
To generate an accurate and production-ready quotation, the following information is recommended:
2D drawings (PDF) or 3D files (STEP / IGES preferred)
Material grade and thickness
Estimated annual or project volume
Critical tolerances and functional requirements
Surface treatment or secondary processes
Delivery destination and target lead time
If drawings are incomplete, our engineers can assist with DFM optimization to improve manufacturability, reduce tooling cost, and avoid future production risks.
What materials are best suited for custom metal stamping parts?
Material selection depends on strength, formability, corrosion resistance, and application environment. Commonly used materials include:
Stainless steel (304, 316, 430)
Carbon steel (SPCC, Q235, AISI 1010–1020)
Aluminum alloys (5052, 6061)
Copper & brass
Spring steel
Choosing the right material directly affects tool life, stamping stability, and final part cost. Material recommendations are provided based on your industry standards and performance requirements.
What tolerance levels can be achieved in custom stamping parts?
Tolerance capability depends on part geometry, material thickness, and stamping process:
Standard stamping tolerance: ±0.1 mm
Precision progressive stamping: up to ±0.05 mm
Critical functional features: controlled via in-die forming or secondary machining
For tight-tolerance components, we apply process control, tool validation, and in-process inspection to ensure dimensional consistency across mass production.
How do I choose between progressive stamping and deep draw stamping?
The choice depends on part structure and production volume:
Progressive stamping is ideal for high-volume parts with multiple features, offering high efficiency and stable quality.
Deep draw stamping is used for deep, hollow components such as housings and enclosures, requiring uniform wall thickness and structural strength.
Our engineering team evaluates geometry, tolerances, and cost targets to determine the most suitable stamping process.
What is the typical lead time for custom metal stamping projects?
Typical project timelines are as follows:
Tooling design & fabrication: 15–30 days
Initial samples: 7–10 days after tooling completion
Mass production: 3–5 weeks depending on order quantity
For repeat orders using existing tooling, lead times are significantly shorter. Urgent projects can be supported with expedited production schedules.
Can custom metal stamping parts include secondary operations and assembly?
Yes. In addition to stamping, we provide integrated secondary services, including:
Deburring and polishing
Tapping and threading
Welding and sub-assembly
Heat treatment
Surface finishing (zinc plating, powder coating, anodizing, etc.)
Offering one-stop processing helps reduce supply chain complexity, control quality, and shorten overall delivery time.
