Metal stamping parts play a vital role across diverse industries such as automotive, electronics, and aerospace. These metal parts are shaped and formed using a stamping press and tool and die surface. To meet the specific project requirements of our customers, Xinzhu Hardware offers custom metal stamping services tailored to various shapes and sizes. The tooling can be adjusted to create a versatile manufacturing process, allowing for the efficient production of customized parts.
The Metal Stamping Processes
The metal stamping process involves several stages to shape and form metal sheets.
Tooling Manufacturing
Tooling is a crucial aspect of metal stamping as it determines the final shape and features of the stamped part. Before the production process begins, the tooling must be manufactured. At Xinzhu Hardware, our experienced toolmakers design and create the tooling in-house, considering factors such as bending, blanking, forming, and other required operations for the specific project. The tooling undergoes rigorous testing to ensure it meets the requirements and produces accurate and consistent parts.
Following the preparation of the tooling, various processes are used for custom metal stamping. These processes include blanking, bending, pressing, drilling, welding, surface treatment, assembling, and more. Simple metal parts may only require 1-2 processes, while complex parts may require multiple processes during production.
Blanking
In metal stamping production, the first step is blanking. During this stage, the sheet metal is placed in a stamping press, and a tool and die surface apply force to deform the metal and cut it into the desired shape. Blanking involves cutting the sheet metal into a flat shape, leaving behind the desired outline of the part.
Bending
After blanking, the next stage is bending. Bending involves deforming the metal sheet to create angles or curves according to the part’s design. A bending die is used in conjunction with the stamping press to apply pressure and shape the metal. Precision and accuracy in the bending process are essential to ensure that the final part meets the required specifications.
Pressing
Pressing is a fundamental step in metal stamping that involves applying force to the metal sheet to create features such as embossing, ribbing, or raised sections. The metal sheet is fed into the stamping press, and the die exerts pressure on the sheet, shaping it into the desired form. This process requires precision and control to achieve consistent results.

Other Processes for Custom Metal Stamping Parts
Drilling
In some cases, additional holes or openings may be required in the stamped part. Drilling is the process of creating these holes using specialized drilling equipment. The position and size of the holes are carefully determined based on the part’s design requirements. Drilling ensures that the final part is ready for assembly or further processing.
Welding
Welding is a commonly used technique in metal stamping to join multiple stamped parts together. It involves melting and fusing the metal surfaces to create a strong and durable bond. Welding can be performed using various methods such as spot welding or arc welding, depending on the materials and specific requirements of the parts being joined.
Surface Treatment
Surface treatment is an essential step in the metal stamping process. It involves applying a coating or finish to the stamped parts to enhance their appearance, protect against corrosion, and improve their overall durability. Common surface treatment methods for metal stamping include plating, powder coating, painting, anodizing, passivation, and mechanical finishing.
Assembling
The final step in the metal stamping process is assembling the stamped parts. This may involve joining multiple stamped components together, attaching additional hardware or fasteners, or integrating other non-stamped parts. Assembling ensures that the final product is complete and ready for use or further processing.
Materials
Various metals can be used for stamping, including steel, stainless steel, aluminum, brass, and galvanized steel. The choice of material depends on the specific requirements of the part and its intended application.
By understanding the different stages involved in custom metal stamping, you can appreciate the intricacies of this process and make informed decisions for your manufacturing projects. Partnering with experienced metal stamping service providers like Xinzhu Hardware ensures the successful realization of your project’s requirements and the production of high-quality stamped parts.
