Qu'est-ce que la fabrication métallique ?
Metal fabrication is a process for creating structures and parts from various metal materials. It involves cutting, bending, shaping, and assembling metals to form custom products. It covers various techniques used to make everything from car frames to electronic enclosures.
It helps create both custom prototypes and high-volume parts. Fabrication allows manufacturers to achieve accuracy, consistency, and cost savings across different projects.
Types of Metal Fabrication Processes
Metal fabrication includes various processes, each serving a specific purpose. These processes help create parts with the proper shape, strength, and size for different applications.
Coupe
Cutting is one of the most common methods in metal fabrication. It involves dividing a metal piece into smaller sections. Traditional methods, like sawing, are still used today. However, modern techniques like power scissors, jet d'eau, laser, et coupage au plasma offer greater precision. These methods are efficient for shaping metal or preparing it for further processing.
Cutting can be done in various ways, using power, manual, or CNC cutters. Depending on what’s needed, it can be the first or the last step in the process. Die cutting, where sharp-edged tools are used to slice metal, is another popular cutting method.
Pliant
Pliant is used to create curved shapes in metal. It’s a key part of fabrication de tôles. Machines like press brakes apply force to bend the metal into the right shape. The bending method depends on factors like the material’s thickness, shape, and angle.
This process is essential for making supports, boîtes, and ducts. It can also be used to create more intricate designs. A challenge in bending is to avoid cracking or deforming the material during the process.
Soudage
Soudage involves joining metal pieces by melting them and adding a filler material, creating a strong bond between them. There are different types of welding, such as Soudage MIG (Métal Inert Gas), Soudage TIG (Tungsten Inert Gas), et soudage par bâtons. Each type is suited to different materials and uses.
Welding is commonly used to make heavy-duty parts and structures. It’s vital in industries like construction, automotive, and aerospace. The quality of the weld is crucial for ensuring the strength and durability of the final product.
Estampillage
Estampillage is a process where a metal sheet is pressed into a die to form a shape. It is excellent for high-volume production because it can create complex shapes quickly and accurately. The die is designed with sharp edges to ensure clean cuts.
Stamping is often used in the automotive and electronics industries to make parts like brackets, covers, and panneaux. It’s an efficient and cost-effective method for large-scale production runs.
Usinage
Machining is removing material from a workpiece to shape or finish it. Tools like drills, lathes, and Machines CNC are used to cut, moudre, or polish the metal. Machining is ideal for producing precise parts with tight tolerances.
It’s often used for making detailed and intricate components. The process works well with many materials, such as metals, plastics, and composites. Its main advantage is the ability to create complex, precise parts.
Extrusion
Extrusion is a method where a material, usually metal, is forced through a die to create a continuous shape with a fixed cross-section. The material is heated before being pushed through the die, shaping the final product.
This process makes long products like pipes, rods, and beams. Depending on the die, the shape can be customized, making extrusion versatile for simple and complex profiles.
Fonderie
Fonderie involves pouring liquid metal into a mold, allowing it to cool and harden. The mold’s shape determines the final product. This method helps create large or complex shapes that are hard to achieve through other processes like machining or stamping.
Casting is commonly used for parts that need to be strong and durable, such as engine blocks and industrial machinery components. Metals like aluminum, steel, and bronze are often used in casting.
Formant
Formant is a broad category of processes that shape metal without removing material. These methods use force to bend, stretch, or compress the metal into the desired form. Standard forming techniques include rolling, forging, and deep drawing.
Forming is ideal for making parts that require high strength and durability. It’s used in industries like automotive manufacturing to create body panels, cadres, and structural components. The main advantage of forming is that it keeps the material’s integrity while creating complex shapes.
La fabrication additive
Additive manufacturing, or 3D printing, involves building up layers of material to create a part. This method is commonly used for rapid prototyping and low-volume production. It can produce highly complex and customized parts that would be difficult to create with traditional methods.
This technology is growing in aerospace, automotive, and medical devices. Additive manufacturing allows for lightweight structures and detailed designs while minimizing material waste.
