Definition of Sheet Metal
In its simplest form, sheet metal is a thin, flat piece made from the more prominent metal roll. The metal sheet is uniformly thin, no more than 6mm thick. This makes it flexible and ideal for different manipulation techniques. Metal sheets come in many other materials, such as stainless, aluminum, brass, and copper. Each material has its unique properties.
We often work with different alloys, sizes, and grades of sheets at Shengen to meet the needs of industries from aerospace to automotive. Sheet metal, whether it is the lightweight flexibility and strength of aluminum or the durable power of steel, has a lot of potential. It just needs the right design.
Sheet Metal Design: It’s Important
Sheet metal is not only beautiful in its raw state but also in its transformational potential. Sheet metal designers realize this potential during the design phase. Designing sheet metal involves conceptualizing, planning, and creating objects from these thin sheets. We can transform these thin sheets by cutting, bending, and punching.
Look at the sheet metal components in the car or plane you use. We have worked with many clients with different requirements. When Jack Garcia wanted gold-plated parts, it wasn’t about aesthetics but durability and functionality.
Basic Principles of Sheet Metal Design
To truly understand and utilize sheet metal’s potential, it is essential to learn its fundamental principles. Explore these basic principles with me.
Material Selection and Properties
Selecting a suitable material is at the core of any successful sheet metal design. Each metal has unique properties, from tensile to malleability to corrosion resistance and thermal conductivity. Understanding these properties is essential.
- Roestvrij staal: This material is known for its corrosion and staining resistance. People primarily use it in outdoor applications and the medical industry.
- Aluminium: Aluminum is lightweight and malleable. The aerospace industry often uses it for parts needing less weight but requiring a reasonable degree of strength.
- Copper and Brass： People use them in decorative and electrical elements due to their malleability and conductivity.
Material properties are not just about function. They also impact the fabrication process, the tooling required, and the cost. At Shengen, before bringing any design to life, we consult our clients to grasp their requirements and recommend the best materials.
Geometry and structural considerations
The magic of sheet-metal design unfolds when you transform a two-dimensional metal piece into a three-dimensional object. This transformation also brings with it the need to be very careful.
- Buigen: You must consider the bend radius and ensure that it is compatible with the thickness of the material. Metal can crack if the bend is too tight.
- Hole Location: To prevent tearing, you should place holes at least the thickness of the material away from any edges.
- Formed Features: Features such as louvers or embossments require enough space between themselves and other elements to avoid structural problems.
Geometry and structure aren’t just about functionality. It’s also about optimizing the design for manufacturing, reducing costs, and minimizing waste. This delicate balance requires expertise and experience.
Tolerance and precision
Even a millimeter makes a difference in the world of sheet-metal design. Understanding and setting appropriate tolerances is vital to ensure that parts fit together. This principle ensures that pieces fit together and maintain functionality, particularly in sectors such as automotive and aerospace, which depend highly on precision.
- Fit & Function: You might need a tighter tolerance for parts requiring a smooth fit without play.
- Kostenoverwegingen: Tighter tolerances may increase production costs. It’s essential to strike a balance between precision and economic efficiency.
We invest in the latest technology and training to ensure our final products and designs are always tolerable. This provides high-quality and reliable components for our clients.
Sheet Metal Design: Key Processes
Transforming a simple metal sheet into a sophisticated component with a purpose involves many processes. We’ve perfected and refined these processes to ensure that each piece leaving our workshop represents our commitment to excellence. We’ll take a journey to learn about the critical stages of sheet metal design.
Bending and folding Techniques
The art of folding and bending gives sheet metal its shape. We transform flat sheets into dynamic three-dimensional components.
- Vbending: Pressing the sheet against a V-shaped die and punch is one of the most common methods we use for bending.
- U bending: The sheet is turned into a U shape using a U-shaped energy and die.
- Coining： Coining is a high-tonnage procedure that controls the bend radius by embedding a punch shape in the sheet.
These techniques allow us to achieve intricate designs with precise angles and ensure the structural integrity of the final product.
Cutting and Shearing Techniques
You must cut the sheet metal into the desired form before bending and folding it. We’ve used various techniques over the years and always put precision first.
- Laser Cut: This method uses a high-power laser beam to cut intricate designs.
- Turret Punching: Engineers designed this machine for repetitive, high-volume tasks.
- Shearing: Shearing is a straightforward process where you cut large sheets into smaller sizes before detailed cutting or punching.
Shengen chooses the best cutting method for each project based on its requirements. This ensures efficiency without compromising quality.
Joining and fastening approaches
After shaping the components, assembling or joining them is often necessary. Our expertise in joining techniques is what makes us stand out.
- Lassen:In welding, you fuse two pieces using heat. TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) are our workshop’s two most common welding techniques.
- Klinkend: These rivets are ideal for joining heavy sheet metal components without heat.
- Puntlassen： Spot welding involves applying an electric current at specific points to form a welded joint.
Surface Finishing Treatment
The final touch ensures not only the aesthetics but also the functionality of the component.
- Poedercoating: Powder coating is a dry finish with a durable and attractive appearance.
- Plating: An electrolytically deposited layer of another metal, such as nickel or gold, enhances corrosion resistance.
- Anodiseren: This process increases the wear resistance on aluminum parts and creates a more adhesive surface for paints and glues.
Software Tools and Digital Advancements
While deeply rooted in centuries-old traditions, the highest quality digital technologies have enhanced the symphony sheet metal design. These innovations reflect our commitment to innovation and providing unparalleled value to clients.
Computer-Aided Design in Sheet Metal
CAD software has revolutionized how we design sheet metal. Our design team is no longer limited to paper sketches or manual calculations. Instead, they use CAD software and its incredible precision to bring ideas to life.
- 3D and 2D Modeling:CAD lets you see your design in three and two dimensions.
- Design refinement: You can make rapid iterations digitally before you start any physical work. This saves both time and resources.
- File-sharing: Working with clients such as Jack Garcia is seamless. Designs can be shared and reviewed in real time and even modified.
Finite Element Analyses for Structural Integrity
Although aesthetics matter, you must ensure the structural integrity of sheet metal components. Finite Element Analysis is the tool that we use.
- Stress Test:FEA simulates the forces and stresses a component may experience during its lifetime, ensuring that it does not fail under pressure.
- Material Optimization: By understanding stress points, we can adjust the material thickness or reinforce certain areas, achieving an equilibrium between strength and material conservancy.
- Voorspellende analyses: This tool provides insight into possible wear and tear. It allows us to address potential vulnerabilities proactively.
Sheet Metal Prototyping using 3D Printing
Including metals in 3D printing marks a significant leap forward for prototyping.
