Sheet metal fabrication refers to the manufacturing process used when making complex parts. It involves modifying flat sheets of metal into desired shapes and sizes. Multiple techniques are employed to carry out this method.
Precision engineering services like these are used across various industries, such as aerospace, automotive, defence, construction and more. Whether you are an engineer, manufacturer or are simply interested in the domain, keep reading. This blog will cover everything from the basics of sheet metalwork to its processes, materials and benefits.
The Basics of Sheet Metal Fabrication
It is the process of sheet cutting, bending, sheet forming, welding and assembling applied to metals in order to curate and design functional components or products. These help in producing accurate and strong metal parts through precision tools. It involves both manual and automated techniques to bring about the desired shapes and sizes of metal sheets.
Sheet Metal Fabrication: Understanding the Process, Materials and Applications
Every metal fabrication company follows more or less the same process to shape metal sheets. It does not consist of a single main method but is, in fact, a series of techniques followed to derive the end results of functional parts.
1. Sheet Cutting
Cutting is one of the oldest processes used in metal manufacturing. The modern cutting stage involves removing unwanted or excess material from the sheet. It includes laser cutting that leads to tight tolerances and high accuracy. Harnam Engineering utilises the following to deliver high-quality results:
- Trumpf TruLaser 3040 4kW fibre optic laser
- Automatic pallet changer
2. Bending
An expert metal fabrication company, such as Harnam Engineering, covers your CNC bending needs. The bending is used to form the metals into V, U shapes or heavy folds. It consists of the following to deliver excellence with each component:
- Expert control system
- Folding machines
3. Sheet Forming
Forming is a critical stage in sheet metalwork, as it enables the production of complex component shapes. This method alters the shape of the product without removing any extra material, while maintaining the strength and sturdiness. Here’s what the sheet forming stage comprises:
- Stamping
- Deep Drawing
- Spinning
4. Welding
It refers to the joining of two parts using heat, pressure or by combining both. Harnam Engineering and its welding services promise reliable and accurate outcomes. They provide various welding services, including:
- Laser Welding
- MIG
- TIG
- Spot welding
5. Finishing
The last stage of finishing involves processes that contribute towards the enhancement of the appearance and functionality of the produced components. They work to elevate the longevity of the products. These methods include:
- Powder Coating
- Andonising
- Electro-plating
- Polishing and painting
Materials Used Commonly During Sheet Metalwork
Sheet metal fabrication can be applied to various metals, depending on the requirement and usage. Here are some metals that are used most commonly:
- Stainless Steel
It is corrosion-resistant and easy to work with, ideal for hygiene applications.
- Aluminium
Aluminium is widely used in the aerospace and automotive industries. It is lightweight and naturally corrosion-resistant.
- Copper
Copper has remarkable electrical and thermal conductivity, making it perfect for wiring and roofing.
- Brass and Bronze
They’re popular for their golden appearance and resistance to tarnish. Hence, both are suitable for architectural and artistic applications.
Applications of Sheet Metal Fabrication
Sheet metal fabrication is widely used in various industries and serves multiple purposes. It has revolutionised manufacturing, making production of components quick and cost-effective.
- Automative Industry
Precision engineering services like sheet metal fabrication play a significant role in the automotive industry. It assists in vehicle construction, including car body panels.
- Aerospace
Metal sheets are utilised for a number of complex parts from the aerospace industry, such as aircraft skin and structural components, as well as engine components.
- Construction And Architecture
Manufacturers use sheet metal fabrication to construct roofing, cladding, staircases and railings.
- Consumer Products
From kitchen appliances to computers and furniture, various consumer products make use of metal steelwork.
