What are the skills of sheet metal processing
With the continuous increase of sheet metal processing products, the development speed of the sheet metal processing industry is getting faster and faster, and the scope of use is becoming wider and wider. Due to the wider and wider use conditions of products, consumers pay more attention to the level of sheet metal processing technology. . Mechanical engineers must be proficient in the skills of sheet metal parts, so that sheet metal not only meets the requirements of product function and appearance, but also makes stamping die manufacturing simple and low cost. Below, the editor of Boyuan Hardware will share the processing skills of sheet metal processing.

The skills of sheet metal processing are as follows:
- In order to prevent the broken debris from hurting people, install a transparent baffle in a suitable position.
- Band-shaped debris will occur under normal working conditions of sheet metal processing. The shape is long debris. It should be cleaned up immediately with a hook. Be careful not to pull it directly by hand.
- It is not allowed to put tools and fixtures on top of it, as well as on the speed change equipment. In the case of running, you must concentrate your thoughts, and you cannot control fatigue, many people and smoking.
- When it is suitable to use gauze to grind the surface of parts, move the tool to a stable position, and pay attention not to let hands and clothes touch the surface. In the case of holes in the grinding, you can’t use your fingers to hold the gauze, you must use something else instead, and the speed should not be too fast.
The above content is shared here. During sheet metal processing, in order to achieve the purpose of reducing investment, it is necessary for the staff to strictly follow the production specifications to complete the work process. Before each processing, the application of the material needs to be reviewed. , without approval, can not be processed casually.
Many people wonder about the difference between sheet metal stamping and deep drawing. There are many differences between the two manufacturing techniques. Read on to learn more about the differences and basic information like production costs and quality.
Sheet metal stamping
The sheet metal stamping process is accomplished by stamping hot-rolled or cold-rolled steel sheet into the shape required to manufacture the part. The technology allows for the simultaneous production of a large number of components, but can also result in about 15 points of raw material becoming waste. This method uses equipment that requires less space than other methods, so if you’re limited in space, this build may be best for your business. There are three main types of dies for sheet metal stamping – cutting, punching and bending.
Cutting involves cutting parts from sheet metal. This is done by stamping sheet metal with a die. The die cuts the sheet metal into the desired shape. There will be burrs on the edges of stamping parts, which need to be flattened or processed before use.
Stamping involves placing a metal sheet between two dies, pressing them together, and punching holes in the metal sheet.
Bending is the use of die pressure to deform metal. This stamping is often used to make parts with curves.

Advantage
low cost
Sheet metal stamping is a low-cost manufacturing technique. Its cost is generally lower than other methods and is ideal for small businesses with limited budgets. It is also considered low cost by many as this method does not require molds or tools to create the part or parts. However, free tools for sheet metal stamping can sometimes make it more expensive because you pay for someone’s layout and design instead of using standardized tools.
mass production
Sheet metal stamping can make thousands of identical parts at a time, so this type of manufacturing allows you to efficiently manufacture large numbers of products while maintaining quality standards. This advantage mainly applies to parts with simple shapes that do not require mass customization.
easy to use
Shears, punches, and bending dies make up most of the tools for sheet metal stamping, so this type of fabrication is relatively easy to learn. If you have employees who are familiar with basic machine operations, they probably know how to punch sheet metal without too much trouble.
Multifunction
Sheet metal stamping is a very common manufacturing technique that can produce parts of various shapes and sizes. This makes it a good choice for businesses that need mass production. Also, this type of stamping can create and complex parts.
Disadvantage
Scrap
Sheet metal stamping has an inherently high rejection rate. Stamping dies require smooth sheet metal surfaces to function properly. If the sheet is uneven, the effect will be poor and the metal bixu will be scrapped. Because this manufacturing process requires a large area of sheet metal, you can waste a lot of small parts that don’t meet quality standards. Obviously, mass production will increase your waste count.
Not easy to customize
Simple and clear machine parts are rarely customized, and sheet metal stamping technology works best. Simple shapes and curves make manufacturing easy and cheap. However, you may have to pay more when using the technology on custom projects or highly detailed parts due to the design fees and additional labor costs required to complete the project.
Limited design and size options
Sheet metal stamping is the best method of manufacturing simple parts, but if you need more complex or detailed parts, it may not be the best option for manufacturing. Stampings used in sheet metal stamping are not prone to tight curves or intricate details, so if you have a complex part design, you may need to find another approach.
Production is slow
Sheet metal stamping is labor-intensive and generally slower than other manufacturing techniques. This can be a significant downside if you need a significant amount.

What is deep drawing?
Deep drawing is a manufacturing process in which a sheet of metal is forced into a mold, where the material is drawn into its final shape. Its main advantage is the ability to create complex shapes quickly and efficiently. This type of stamping can be an ideal choice because it can accommodate almost any design constraints, while deep-drawn parts are more durable than stamped parts because they wear out slightly during production.
Advantage
mass production
Drawing can produce large quantities of high-quality parts quickly and efficiently. This makes it an attractive option for businesses that need to create many products in a short period of time.
easy to use
The deep drawing process is relatively simple and ideal for businesses looking to save on labor costs. This stamping does not require the expertise of other methods, so it is relatively easy for your employees to learn how to operate the machine.
Adapt to complex designs
As mentioned earlier, deep drawing can easily create complex parts without design constraints. This makes it a good option for businesses that need unique or custom metal parts without paying extra for a design.
flexibility
The advantage of deep drawing is that various material types can be used. This can be especially beneficial if you’re trying to reduce costs or improve product quality by switching from one metal type to another.
multifunctional industry
If you need help with a mechanical problem or more information about the manufacturing process, you can contact more experts to help you with your work, as deep drawing is already used in many industries.
Disadvantage
Risk of high rejection rate
Deep drawing can lead to high waste rates if the wrong material is used or the metal is not adequately prepared before fabrication. For deep drawing to be successful, the metal needs to have no scratches, bumps or other irregularities. If the part is defective in any way, it needs to be scrapped and replaced with a new part.
higher cost
Dies and tooling are more expensive than sheet metal stamping due to the complexity of the deep drawing process. This can be challenging to produce high-quality parts at a reasonable cost.
short lifespan
Deep drawing can reduce the life of parts because they are not as durable as parts made by other manufacturing methods of sheet metal stamping, such as bending. Deep-drawing parts are subject to continuous tension during the deep-drawing process, and are prone to surface deformation and bending. This requires careful inspection of each part after production, which adds additional labor costs to the overall manufacturing budget.
