When it comes to producing shapes or frames that will meet an industry’s demand, it is best to use precise methods that will yield the desired result. You will also notice that the various industries that deal with professional metal parts are looking for low-cost production methods.
Many businesses are aware that the cost of producing these shapes is high, so to save money, they use the efficient and cost-effective method of metal stamping. This method also allows these engineers or companies to reduce production costs while maintaining the expected quality.
What is Metal Stamping?
Metal stamping tooling, also known as pressing, is a low-cost, high-speed manufacturing process. It is capable of mass- production of identical metal components. Stamping operations are suitable for both short and long production runs. It can also work in conjunction with other metal forming operations. Stamping operations may include one or several specific processes or techniques, such as:
The most fundamental technique, blanking begins when the sheet or blank is fed into the press, where the die cuts out the desired shape. The resulting piece is referred to as a blank. The blank may be the desired part, also known as a fully finished blank, or it may proceed to the forming step.
Piercing, also known as punching, is a method of shearing a metal sheet or plate by punching a hole in it with a punch and die. In this process, the unused portion of the metal object is removed and becomes scrap.
Bending is the process of deforming a piece of metal so that the dimensions and width before and after remain the same. The process only modifies the metal piece’s shape.
The process of transforming flat metal into another shape by applying force is referred to as form. It is accomplished in one of several ways, depending on the part’s design specifications. The metal can be transformed from a relatively simple shape to a complex one through a series of operations.
Types of Stamping Operations
Progressive die stamping
This type of progressive stamping press consists of a couple of stations, each of which serves a specific purpose. The metal strip is first pressed and then unrolled into a die press. This is the stage at which each station performs a distinct cutting, punching, or bending function. Each station’s actions add to the work of the preceding stations, resulting in a complete part.
Transfer Die Stamping
Transfer die stamping is similar to progressive die stamping in that the part is separated from the metal trip early in the process and transferred from one stamping station to the next using another mechanical transport system, such as a conveyor belt.
Four-slide stamping is also known as multi-slide stamping or four-way stamping. This method is best suited for creating complex components with multiple bends or twists. It shapes the workpiece through multiple deformations using four sliding tools rather than one vertical slide.
Metal Stamping: Advantages
Stamping has several advantages over other processes, including lower die costs, lower secondary costs, and a high level of automation.
- Metal stamping dies are typically less expensive to manufacture and maintain than dies used in other common processes. Secondary costs, such as cleaning and plating, are also lower than for other metal fabrication processes.
- Stamping machines are relatively simple to automate and can use sophisticated computer-control programs to provide greater precision, faster production, and shorter turnaround times.
Metal Stamping: Disadvantages
Because this technique requires tooling in advance, low-scale and short-term production are costly and inefficient, because the development and manufacture of equipment take a long time, and if any changes are required, extra expenses and hardships in modifying the equipment may arise
In a nutshell:
The metal stamp technique’s rapidly developing and expanding technical capability is outpacing many metal formation techniques, particularly in the case of large-scale runs of highly accurate production.
The technique requires skills and expertise to create metal stamped components with tight tolerances and complex geometries. This is important for applications where metal part design plays a critical role in the functioning of equipment.
Therefore, most electrical and electronic manufacturing companies trust a metal stamping company like Eigen engineering which has a team of metal stamping experts who understand product requirements and design the tools to create highly precise metal parts.
