CSMFG produces custom stamped metal parts using blanking, bending, piercing, coining, drawing, progressive dies, and high-speed stamping. The service fits OEM buyers that need repeatable sheet metal parts with secondary finishing.
We are an American owned manufacturing company in China with strong capabilities in:
Normal stamping (Blanking, Bending, Forming, Piercing, Coining…) Progressive die- / high-speed stamping Robot stampingFrom low to high quantity items we are your preferred manufacturer for stamping products. We provide all secondary finishing processes such as welding, bending and surface treatment like powder coating and anodizing
| Our common stamping operations | |||||||
| Bending | The material is deformed or bent along a straight line | ||||||
| Flanging | The material is bent along a curved line | ||||||
| Embossing | The material is streched into a shallow depression. Used primarily for adding decorative patterns. | ||||||
| Blanking | A piece is cut out of the sheet of the material, ususally to make a blank for further processing | ||||||
| Coining | A pattern is compressed or squeezed into the material. Traditionally used to make coins | ||||||
| Drawing | The surface area of a blank is streched into an alternate shape via controlled material flow. | ||||||
| Stretching | The surface area of a blank is increased by tension, with no inward movement of the blank edge. Often used to make smooth auto body parts | ||||||
| Ironing | The material is squeezed and reduced in thickness along a vertical wall. Used for beverage cans | ||||||
| Reducing / Necking | Used to gradually reduce the diameter of the open end of a vessel or tube. | ||||||
| Curling | Deforming material into a tubular profile. Door hinges are a common example. | ||||||
| Hemming | Holding an edge over onto itself to add thickness. The edges of automobile doors are usually hemmed | ||||||
Each stamping operation has its advantages and disadvantages. We choose the most cost effective for your product!
One stop solution for all your steel products with all manufacturer possibilities inclusive tooling and mold design and execution in-house.
We can offer short manufacturing lead time for the manufacturing of new products and existing products from prototyping to mass production.
We have the capabilities to manufacture complex, high precision parts.
If you need secondary/finishing processes such as welding, riveting, powder coating, anodizing and/or assembly, our assembly lines will take care of it. We can deliver sub-assembly and finished products.
Our stamping process is highly automated and efficient with our robot-stamping equipment.

CSMFG produces custom stamped metal parts using blanking, bending, piercing, coining, drawing, progressive dies, and high-speed stamping. The service fits OEM buyers that need repeatable sheet metal parts with secondary finishing.
The page lists stamping operations and includes OEM project examples, including parts that also require bending, welding, and surface treatment.
For faster sourcing decisions, include the commercial context as well as the drawing package: target unit cost, expected order frequency, approval steps, packaging needs, destination market, and any standards the part must satisfy. This helps CSMFG compare tooling cost, process risk, inspection level, and production routing before quoting.
Buyers should also identify the part's end use, failure risks, cosmetic surfaces, and any regulatory or customer-specific requirements. Those details help align sampling, inspection reports, packing methods, and long-term production controls.
| Materials | Steel, stainless steel, aluminum, brass, copper alloys, galvanized sheet, and coated sheet materials selected to drawing requirements. |
|---|---|
| Tolerances | Stamping tolerances depend on material thickness, die design, bend geometry, springback, and secondary operations. |
| Batch sizes | Prototype and pilot parts are possible, while progressive tooling is strongest for medium and high-volume production. |
| Lead times | Lead times depend on tool complexity, material sourcing, sample approval, plating, powder coating, or assembly needs. |
| QC checks | First article inspection, in-process dimensional checks, finish verification, and final lot inspection before packing. |
| RFQ requirements | Send 2D drawings, flat patterns if available, CAD files, material, thickness, finish, quantity, and critical dimensions. |
Common operations include blanking, bending, flanging, embossing, coining, drawing, piercing, and progressive die stamping.
Low-volume stamping can be reviewed, but hard tooling is usually most cost-effective for repeat or higher-volume parts.
Yes. Stamped parts can be quoted with welding, bending, plating, powder coating, anodizing, and assembly.
