CNC machining often complements stamping for secondary operations, but is not the primary forming method.

Key Process Steps:

1. 1. Design and Engineering: The process begins with detailed CAD/CAM design of the part and the necessary tooling. This involves material selection based on mechanical properties, formability, and application requirements, as well as simulating the stamping process to identify potential issues like springback or tearing.
2. 2. Tooling Fabrication: Dies and punches, typically made from hardened tool steel, are custom-fabricated. The quality and precision of the tooling are paramount as they directly influence the final part's accuracy and the longevity of the production run.
3. 3. Material Preparation: Metal sheets or coils are selected based on the specified material (e.g., cold-rolled steel, stainless steel, aluminum, copper, brass) and cut to appropriate sizes for feeding into the press. Materials are chosen for properties such as corrosion resistance (e.g., stainless steel for petrochemical), strength, and ductility.
4. 4. Stamping Operations:
   • Blanking: Cutting the basic flat shape (blank) from a larger sheet.
   • Forming/Bending: Shaping the blank into a three-dimensional form, often involving multiple stages of bending or drawing.
   • Piercing/Punching: Creating holes or cutouts within the part.
   • Trimming: Removing excess material from the edges of a formed part to achieve final dimensions.
   • Coining: Pressing a metal blank in a die to produce fine details or a specific thickness.
5. 5. Secondary Operations: Post-stamping treatments may include deburring, cleaning, heat treatment, welding, machining (e.g., CNC milling for precise features), and surface finishing (e.g., powder coating, plating for enhanced corrosion resistance or aesthetics).
6. 6. Quality Control and Testing: Throughout the process, parts undergo rigorous inspection. This includes dimensional checks using CMM (Coordinate Measuring Machine), material hardness testing, visual inspection for defects, and functional testing to ensure adherence to specifications.

   Testing standards frequently followed include ISO 9001 for quality management systems, IATF 16949 for automotive components, and various ASTM and ANSI standards for material properties and testing methods.

7. 7. Assembly and Packaging: Finished oem stamping parts are assembled if required and then packaged according to client specifications for safe transit.

The service life of oem stamping parts is highly dependent on material selection, design, manufacturing precision, and the operational environment. For example, stainless steel components used in petrochemical environments are engineered for decades of corrosion resistance, while high-strength steel parts in automotive applications are designed to withstand millions of stress cycles.
