The sheet metal stamping process works by stamping hot or cold rolled steel sheets into the shapes needed to make the part. The technique allows for a large number of components to be produced at once, but it can also result in about 15% of the raw material becoming waste. The equipment used in this method requires less space than other methods, so if you have limited space, this type of manufacturing may be best suited for your business. There are three main types of dies used in sheet metal stamping – cutting, metal spinning,punching, and bending.
Cutting involves cutting parts from sheet metal. This is done by punching the sheet metal with a die. The die cuts the sheet metal into the desired shape. Stamped parts will have burrs on the edges that need to be flattened or machined before use.
Stamping is the process of placing a sheet of metal between two dies, pressing them together, and punching holes in the sheet metal.
Bending is the process of deforming the metal using the pressure of a die. This type of stamping is often used to make parts with curves.
Sheet metal stamping is a low-cost manufacturing technique. It is generally less expensive than other methods, making it a good choice for small businesses with limited budgets. Many people believe that it is also low-cost because this method does not require dies or tools to create the part or parts. However, the free tools for sheet metal stamping can sometimes make it more expensive because you are paying for someone’s layout and design rather than 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 make large quantities of products while maintaining quality standards. This advantage mainly applies to parts that are simple in shape and do not require mass customization.
Ease of Use
Shears, punches, and bending dies make up most of the tools for sheet metal stamping, so this type of manufacturing is relatively easy to learn. If you have employees who are familiar with basic machine operations, they probably know how to stamp sheet metal without too much trouble.
Versatile
Sheet metal stamping is a very common manufacturing technique that can make parts of a variety of shapes and sizes. This makes it a good choice for businesses that need to mass produce. In addition, this type of stamping can create and intricate parts.
Disadvantages
Scrap
Sheet metal stamping has an inherently high rejection rate. Stamping dies require a smooth surface of sheet metal to work properly. If the sheet is uneven, the results will be poor and the metal will be scrapped. Because this manufacturing process requires a large area of sheet metal, you may waste a lot of small parts that do not meet quality standards. Obviously, mass production will increase your waste volume.
Not Easy to Customize
Simple and straightforward machine parts that are rarely customized work best with sheet metal stamping technology. Simple shapes and curves make them easy and cheap to manufacture. However, you may have to pay more when using this 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 choice for a method of manufacturing simple parts, but if you need more complex or detailed parts, it may not be the best choice for manufacturing. The stampings used in sheet metal stamping are not easy to produce tight curves or intricate details, so if your part design is complex, you may need to find another method.
Slow Production
Sheet metal stamping is labor-intensive and generally slower than other manufacturing techniques. This can be a significant disadvantage if you need large quantities.
What is Deep Drawing?
Deep drawing stamping is a manufacturing process that forces sheet metal into a die, with the die stretching the material 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, and deep drawn parts are more durable than stamped parts because they wear slightly during the production process.
Advantages
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.
Ease of Use
The deep drawing process is relatively simple, making it an ideal choice for businesses that want to save on labor costs. This type of stamping does not require expertise like other methods, so it is relatively easy for your employees to learn how to operate the machine.
Accommodates Complex Designs
As mentioned earlier, deep drawing can easily create complex parts without design constraints. This makes it a good choice for businesses that need unique or customized metal parts without spending extra money on design fees.
Flexibility
The advantage of deep drawing is that a variety of material types can be used. This can be particularly beneficial if you are trying to reduce costs or improve product quality by switching from one metal type to another.
Versatile Industries
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 has been applied in many industries.
Disadvantages
Risk of high rejection rate
Deep stamping can result in high waste rates if the wrong material is used or the metal is not adequately prepared before manufacturing. To successfully deep stamp, the metal needs to be free of scratches, bulges, or other irregular surfaces. If the part has any defects, it needs to be scrapped and replaced with a new one.
Higher cost
Due to the complexity of the deep stamping process, dies and tools are more expensive than sheet metal stamping. This can make it challenging to produce high-quality parts at a reasonable cost.
Short lifespan
Deep stamping reduces the lifespan of parts because they are not as durable as parts made by other manufacturing methods such as bend forming for sheet metal stamping. Deep stamped parts are subject to continuous tension during the deep stamping 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.
Gaoduan factory
Deep stamping requires specialized equipment, so it is usually only used by Gaoduan machine factories. If you switch from sheet metal stamping to deep stamping, you may need to invest in new or upgraded equipment, which may be too expensive for some businesses.
Longer Production Time
Deep stamping requires more steps and time than other manufacturing processes such as injection molding and thermoforming. This can make it challenging to stay competitive when meeting tight deadlines or production quotas.
What is the difference between sheet metal stamping and deep stamping?
Cost
The main difference between sheet metal stamping and deep stamping is cost. Sheet metal stamping costs less than deep stamping because it requires more tooling and setup time. This also makes it an economical choice for businesses that need to produce a large number of parts quickly.
Durability
Parts made by sheet metal stamping are more durable than those made by deep stamping. This is because the material is not subjected to as much tension during production, reducing the possibility of surface deformation or bending.
Ease of Use
Compared to deep stamping, sheet metal stamping is a simple process and does not require as much highly skilled labor to operate the machine. This is a good option for businesses to save on labor costs.
Shape and Size
Sheet metal stamping jinxian Deep stamping can produce parts of considerable complexity, detail, and/or size in simple designs as long as the dimensions meet the machine’s capabilities.
Tolerance
Deep drawing tolerances are not as high as sheet metal stamping precision. This means that the dimensions of deep drawn parts vary greatly, which can be a problem for businesses that require tight tolerances. At the same time, the technical requirements are higher.
Material Types
Deep drawing is the most effective for sheet metal, making it a good choice for industries that work primarily with metal. Sheet Metal Stamping Parts can be made of any material, which broadens its appeal across a variety of fields.
