Metal stamping is a common manufacturing process that involves forming flat metal sheets into various shapes and sizes. The process can produce high-quality and consistent metal parts with precise dimensions and tolerances that are widely used in daily life. In this article, we will discuss the process characteristics of metal stamping parts and how they are manufactured.

Metal stamping is a process that involves a series of operations to transform flat metal sheets into complex shapes and sizes. The process includes cutting, bending, stretching, and punching the metal sheet with a stamping press. The stamping press applies pressure to the metal sheet using a die and punch set, which creates the desired shape of the metal part.
The process can be performed on various types of metals, including steel, aluminum, copper, and brass. The thickness of the metal sheet used in the process can range from thin foils to thick sheets.
There are several process characteristics of metal stamping parts that make it an ideal manufacturing process for producing high-quality metal parts. These characteristics include:
Metal stamping can produce highly precise and accurate metal parts with tight tolerances. The process can be controlled to achieve the desired dimensions and shapes of the metal part.
The product quality is stable and the interchangeability is good. The metal stamping die is used to form the product. There are a few factors affecting the change in product quality and the degree of harm is low. Some factors can be corrected by taking appropriate measures so that the quality of the product is controlled within the ideal range, and the stability of the product quality can effectively ensure its interchangeability. Good interchangeability is the basic guarantee for mass production of the assembly line. At the same time, it is also conducive to the maintenance and replacement of products.
Metal stamping is an efficient manufacturing process that can produce large quantities of metal parts in a short time. The process can be automated to increase production rates and reduce labor costs.
The number of parts or process content completed per unit of time is several times higher than that of ordinary processing methods, even hundreds of times. Moreover, the metal stamping process can further improve production efficiency by using one mold with multiple pieces and multiple process contents combined processing on a set of molds.
Through different layout methods, such as cross, oblique, multi-row, mixing, nesting, and even non-waste layout, the utilization rate of materials can be effectively improved and the material cost of products can be reduced.
The material does not need to be heated. Under normal circumstances, the material does not need to be heated during the stamping operation. This can not only save energy, reduce the occupation of heating equipment and space, but also avoid the unstable shape and size of products caused by surface oxidation, burns, and deformation caused by heating. It is also possible to prevent adverse effects on the mold due to temperature rise.
Metal stamping can produce consistent metal parts with uniform shapes and sizes. The process can be repeated to produce identical metal parts with the same dimensions and tolerances.

Metal stamping can be used to produce a wide range of metal parts with different shapes and sizes. The process can be customized to meet the specific requirements of each metal part.
The mechanical properties of punching parts are improved. Affected by the hardening phenomenon of metal stamping, the surface structure of punching parts is tight, the hardness and wear resistance is increased, and the strength and rigidity of punching parts are also improved.
There are many products suitable for stamping and forming. It can solve many processing contents that cannot or are difficult to be completed by general machining, especially for the processing and forming of some thin, soft, difficult, strange, micro parts, or parts of non-metallic materials, metal stamping forming is almost only one method of processing and forming.
The manufacturing process of metal stamping parts involves several steps, including:
The metal stamping process is a cost-effective, efficient, and versatile way to produce high-quality metal components in large volumes. The process involves several steps, including design, material selection, cutting, forming, and quality control. Proper maintenance and safety precautions are essential for the longevity and safety of the stamping equipment. The future of metal stamping process is expected to include more advanced technologies and materials.

There is much more to metal stamping than most people take into consideration.
Complex parts often require a series of several different steps to create. Parts that may seem simple at first glance rarely need only one stamping step to be considered properly completed.
Confusion is often found when determining the appropriate process for metal stamping. When selecting a metal stamping process, one should consider:
Disregarding steps such as design and prototyping, which are necessarily performed prior to stamping, there are nine primary processes involved in the actual stamping of metal parts.
When required, blanking is the first step of the stamping process. Blanking is the process of cutting larger sheet or coils of metal into smaller, more manageable pieces. Blanking is usually performed when a stamped metal piece will be drawn or formed.
If a part requires slots, holes, or other cutouts, piercing can be employed. Piercing, which can be performed simultaneously with blanking, punches the requisite shapes out of the metal sheet.
Drawing is the actual stamping in the metal stamping process. A punch forces a section of metal through a die, providing the primary shape of the part. When the depth of the part is less than the primary opening, it is considered shallow drawing; parts with a depth greater than the opening are deep drawn.
Bending is a fairly self-explanatory process. The part-in-progress is placed on a specially designed die and a ram pushes against the metal, providing the required bend. Bending is performed after drawing, as attempting to punch an already bent piece of metal causes the entire part to deform.
Air bending is when the flat surface of a part is bent by a punch into a die, often V-shaped. The space between the punch and die is larger than the metal thickness, resulting in a bend that relaxes slightly when the part is released. Air bending uses less power and pressure than other bending methods.
Bottoming and coining are bending processes are similar to air bending, but use anywhere from two to 30 times the pressure and the material is forced fully into a tight-fitting die, resulting in a more permanent bend.
Forming is a bending process similar to bending, bottoming, and coining. It creates parts with multiple bends, such as U-bends, in one step.
Pinch trimming is a method of cutting a piece from the metal sheet, separating it from the scrap metal. It is an unconventional process: the metal is pinched against a flat vertical surface. It is often, but not exclusively, used to cut deep drawn round cups from the sheet.
A unique process, lancing is a type of metal cutting used to make vents or tabs. A section of a part is cut along three edges and simultaneously bent. This creates the opening or hook-like feature required but eliminates a scrap collection or secondary machining step.
There are many different processes involved in the stamping process and, clearly, not every process is the best, or even required, for every part. With a full understanding of the processes, you can better design parts to minimize scrap, create cost savings, and increase production speed without ever sacrificing quality.
