Compound Die Metal Stamping
Custom compound die stamping for flat precision metal parts requiring accurate inner and outer profiles, stable flatness, and repeatable batch production.
- Simultaneous blanking and piercing in one press stroke
- Custom compound die design and manufacturing
- Suitable for washers, shims, gaskets, rings, plates, and flat components
- Stainless steel, carbon steel, aluminum, copper, brass, and silicon steel
Precision Flat Parts in a Single Press Stroke
Our compound dies perform blanking, piercing, and profile cutting at one station during a single press stroke. Producing the inner and outer features in the same operation helps maintain their positional relationship and reduces variation caused by transferring the part between multiple stations.
This process is commonly used for flat metal parts such as washers, shims, rings, gaskets, plates, retainers, and motor laminations.
Our Compound Die Manufacturing Capabilities
Custom Die Development
Compound dies are designed according to the part profile, hole positions, material thickness, tolerance requirements, and production quantity.
Single-Station Multi-Operation Cutting
Blanking, piercing, notching, and profile cutting can be combined within one press stroke.
Flatness and Positional Control
Die structure, material support, stripping, and part ejection are planned to reduce distortion and maintain stable feature positions.
Tool Trial and Optimization
Tooling is tested and adjusted before sample approval and volume production.
Compound Die or Progressive Die?
| Feature | Compound Die | Progressive Die |
| Stations | Single Station (All-in-one) | Multiple Stations (Sequential) |
| Operation | Performs all cuts in one stroke. | Parts move along a strip for step-by-step processing. |
| Precision | Superior (Best for concentricity). | High (But limited by strip movement/feeding). |
| Flatness | Excellent (No bending stress). | Moderate (Prone to slight warping during movement). |
| Production Speed | Slower (Manual or semi-auto). | Very Fast (Fully automated high-speed). |
| Complexity | Best for flat, 2D parts. | Capable of 3D forms, bending, and drawing. |
| Tooling Cost | Generally Lower. | Higher (Due to multiple stations/complexity). |
Which One Should You Choose?
Choose Compound Die Stamping if:
Your part is flat (like a washer, gear, or shim).
You require extreme concentricity between the inner holes and the outer diameter.
The production volume is medium, and you want to keep tooling costs manageable.
Choose Progressive Die Stamping if:
The part requires bending, deep drawing, or multiple forming steps.
You have high-volume orders (millions of parts) where speed is the priority.
You want a fully automated process to reduce labor costs.
Why Choose Our Precision Stamping Services?
We deliver high-performance metal components with a focus on accuracy, speed, and cost-efficiency.
Ultimate Precision: Our Compound Die technology ensures $\pm 0.02$mm tolerances and perfect concentricity in a single stroke.
Superior Flatness: Ideal for shims, gaskets, and gears where zero warping is critical.
Cost-Effective Tooling: Lower upfront mold costs for medium-to-high volume production.
Expert DFM Analysis: We optimize your designs for better manufacturability and lower per-unit costs.
FAQ
For most compound dies, tooling fabrication and initial samples are usually completed within 15 to 25 days, depending on the part complexity.
We are flexible with order volumes. While we specialize in medium to high-volume production, we also support small batch runs for specialized industrial components or market testing.
Beyond stamping, we offer a full suite of finishing services, including deburring, heat treatment, plating (zinc, nickel, chrome), and powder coating to deliver assembly-ready parts.
We implement strict ISO-standard protocols, including first-article inspection (FAI), in-process sampling every hour, and final dimensional reports using CMM and optical measurement systems.
Yes. We accept all major file formats, including STEP, IGES, DWG, and PDF. If you only have a physical sample, our team can perform reverse engineering to create the necessary technical drawings.
