There are several different types of metal stamping processes. These include punching, deep drawing, and compound stamping. Using each of these methods requires specialized tooling, and they require high investment costs. In addition, changing part designs can be difficult. In this article, we'll cover all of these types. Learn more about each type of metal stamping process. And be sure to check out our other articles on metal stamping, including punching and deep drawing.
Punching
Punching and metal stamping are processes of forming metal parts that create specific shapes. These methods make it possible to meet very tight tolerances because they use significant pressure and precise programming. Compared to other methods, these techniques are quicker and leave a small amount of waste. The punching process uses a variety of presses to create a specific shape. It can also be used to make corners in the metal. Here are some examples of metal stamping and punching processes:
Punching is a process that creates a hole in a metal workpiece by forcing a punch through it. A punch press forces a punch into the workpiece, creating a hole that is shaped by shearing. The slug of metal left behind after punching is either recycled or discarded. Punching is often the quickest and simplest way to create a hole in sheet metal. It also allows multiple usable parts to be made from the same piece of metal.
Deep drawing
The process of deep drawing when metal stamping is performed by using tangential and radial pressure to shape the base material of a blank. Specialized punches and dies reduce the diameter of the blank and increase its length. The resulting piece can be cylindrical, hollow, tapered, or combination of both. The design of the end product is the basis for every stamping operation. The manufacturer determines the dies and the desired stamping techniques based on these specifications.
The deep drawing process is a highly cost-effective method, especially for high-volume manufacturing. The process involves minimal maintenance, repairs, and adjustments of tooling, resulting in lower per-unit costs. Deep drawing also reduces scrap material because the workpiece and strip are separated during the first operation. The resultant parts are highly precise and durable while also being lightweight. Deep drawing is an excellent choice for high-volume manufacturing, especially because it reduces the amount of scrap material.
Deep-drawing
The process of deep-draw metal stamping involves radially drawing flat sheet metal into a die. This process is ideal for producing components with greater depth and length than can be achieved with traditional stamping techniques. Deep-draw stamping is also a cost-effective option compared to turning metal parts. Several dies are used to produce the final part. Deep-draw metal stamping requires less technical labor and reduces production time.
It is a cost-effective manufacturing solution, particularly for high-volume production. The process involves less downtime, and the tooling cost is lower than that of progressive die stamping. Furthermore, deep-drawing is a good choice for products that need considerable strength and minimal weight. It is also a good choice if other manufacturing processes cannot produce the product. This article will explore the two main benefits of deep-drawing and how it can be advantageous for your business.
Compound stamping
Compound stamping is a type of metal stamping that involves the use of a set of dies. A compound die set is designed to cut multiple features into a workpiece in one downward stroke. The parts produced by a compound die set are much more accurate than single-die stamps and can achieve very close dimensional tolerances. Compound stamping is an excellent choice for medium to high-volume production runs.
Compound die stamping involves the use of a series of individual operations in a single stamping stroke. Compound dies are designed to achieve 0.001″ tolerances for concentricity and a wide range of other qualities. They can produce complex shapes in a single pass, and can often save a great deal of money over progressive dies. In addition, these types of dies are usually more durable than progressive dies and are more accurate.
Embossing
In metal stamping, the process of creating raised or indented 3D graphics is called embossing. The term is used in both specialized and general design applications. Embossers are mechanical devices that create unique designs by applying pressure to a metal surface and then engrave the design. In addition, these machines can produce unlimited patterns and are used in medium to high-volume productions.
The growing production of automobiles will drive metal stamping demand. Many automobile components are made using this method, including transmission and interior structural components. Environmental concerns are also driving automobile consumers toward more fuel-efficient and lightweight vehicles. A recent report by LMC Automotive predicted that the number of light-vehicle sales in the U.S. would hit 14.5 million by 2020 and 15.8 million by 2022. Metal stamping plays an important role in various industries, including aerospace, automotive, and jewelry.
