Precision sheet metal fabrication entails forming raw metal sheets into fully completed parts and components, which will be assembled into a final product. It produces an infinite variety of assemblies and other elements, ranging from small pieces used in agricultural machinery to large steel frames for construction purposes.
Many processes are required to complete a product, such as cutting, bending, surface treatment, and assembly. This article will discuss the fundamentals of precision sheet metal fabrications, including their applications and advantages.
What Is Precision Sheet Metal Fabrication?
Precision sheet metal fabrication is a manufacturing process to create highly accurate and intricate components. This method enables engineers and metalworkers to produce complex parts in various sizes and shapes, depending on the required configuration. In addition, computer numerical control (CNC) technology can also be integrated to achieve the highest possible precision.
Most sheet metal fabrication techniques are essential to producing parts and components for various industries. They are widely utilized in the entire transportation industry — automobiles, airplanes, trains, buses, and ships — and are used in the following sectors:
- Agricultural machines and tools manufacturing
- Building and construction
- Consumer products manufacturing
- Electronics and telecommunications
- Medical device and equipment production
- Robotics and automation
Advantages of Precision Sheet Metal Fabrication
Precision is one of the most important determinants of the functionality and durability of a fabricated component. CNC technologies have enabled seemingly unachievable levels of accuracy over the years, allowing the fabrication of metal sheets with the tightest possible tolerances.
Aside from precision, the advantages of sheet metal fabrication include the following:
Repeatability
Precision sheet metal fabrications guarantee that components and parts are perfectly identical to the original design and one another. This is crucial in reducing variances among features on a single production run and ensuring that all succeeding cycles utilize the same CAD/CAM drawing and program.
High-Capacity Production
Sheet metal fabrication enables high-capacity production, which is ideal for businesses that require bulk manufacturing. It also expedites the distribution of completed components to a larger market in a short period.
Reduced Production Costs
Although CNC services have higher upfront costs than traditional processes, they feature inherent cost savings. For instance, a single piece of CNC machine can perform multiple operations simultaneously and allows for the design of machining and fabrication processes. This results in accelerated production and reduced waste.
Wide Range of Surface Finishes
Precision sheet metal fabrication provides various surface finishes that improve the aesthetic value of the part or component. Some of the most common finishes include sandblasting, polishing, grinding, powder coating, plating, and others.
Types of Sheet Metal Fabrication
The following are some of the most commonly used methods in sheet metal fabrications:
Thermal Cutting
Thermal cutting involves using various forms of energy to cut nearly any shape from sheets or large slabs of iron and nonferrous materials. Laser cutting is the preferred method for sheet cutting due to its speed and accuracy, while plasma cutting is used for thicker materials.
Sheet Metal Stamping
The metal is formed simultaneously or with a progressive die during sheet metal stamping. This method is appropriate when there is a recurring, high-volume demand for a product, as it allows for the rapid production of multiple units.
Bending and Forming
Sheet metal bending and forming using CNC or press brakes is the most cost-effective method for creating 2- and 3-dimensional shaped pieces. It is also used to make small alterations to the final product.
Robotic Welding
Robotic welding is a highly developed form of automated welding in which welders continue to control and supervise the welding process. It enables precise and rapid results, less waste, and increased safety.
