Metal Fabrication Guide: Custom Cut Sheet Processes, Applications, and Services

Custom sheet metal fabrication cutting is a fundamental aspect of modern manufacturing. It involves shaping and cutting flat metal sheets into specific parts or products that are tailored to meet particular requirements. The process is used across a variety of industries, including automotive, aerospace, construction, electronics, and more. By utilising different techniques and methods, manufacturers can produce high-quality metal components that are both functional and durable.

This article explores the various methods of sheet metal cutting, the applications of custom-cut metal parts, and the range of services available to businesses and industries in need of custom sheet metal solutions.

Key Methods of Custom Sheet Metal Cutting

Sheet metal cutting can be achieved through a range of processes, each suited to different types of metal, thicknesses, and design complexities. Below are the key methods commonly used in the industry.

• Laser Cutting

Laser cutting is one of the most widely used methods for custom sheet metal cutting. It uses a high-powered laser beam to cut through the metal, which melts, burns, or vaporises the material. 

The precision of laser cutting is unparalleled, making it ideal for intricate designs and small parts. The laser beam can be controlled via computer programming, which ensures precise cutting with minimal human intervention.

Advantages of Laser Cutting:

• Precision: Achieves tight tolerances with minimal deviation.
• Complex Shapes: Capable of cutting highly intricate designs.
• Minimal Material Waste: The laser’s fine beam reduces waste by cutting with high efficiency.
• Clean Edges: Produces smooth, burr-free edges that require little post-processing.

At Kirmell Ltd, our laser cutting services are suitable for materials such as mild steel, stainless steel, and aluminium. We employ advanced fibre laser machines to handle custom thickness requirements while ensuring minimal waste and clean finishes every time.

• Presswork

Presswork involves using a die and a press machine to shape or cut metal. This process typically uses a punch and die to cut out parts from a metal sheet. It is commonly used for producing high-volume, uniform metal parts, such as washers, brackets, and frames. Presswork can be used for both blanking (cutting a metal sheet into parts) and forming (shaping the metal into specific forms).

Advantages of Presswork:

• Speed: Ideal for high-volume production runs.
• Cost-Effective: Especially for the mass production of simple parts.
• Versatility: Can be used for cutting, bending, and forming metals into specific shapes.

Presswork is most effective for parts that have consistent, simple shapes. It is widely used in industries like automotive manufacturing, where mass production of parts is needed. Discover the Advantages of Metal Presswork in Manufacturing for high-volume production efficiency

• CNC Machining

CNC (Computer Numerical Control) machining is a precise method that uses computer software to control cutting tools, allowing for accurate and intricate cuts. It is ideal for creating custom cut sheet metal parts with detailed features or complex geometries. CNC machines can work with a variety of tools, such as mills and lathes, to shape metal into desired forms.

Advantages of CNC Machining:

• Precision: Delivers high levels of accuracy, even for complex designs.
• Flexibility: Suitable for low-volume production and prototyping.
• Versatility: CNC machines can work with a variety of materials and cutting tools.

This method is ideal for components that require a high level of detail, such as custom gears, brackets, and other specialised parts used in high-tech industries.

• Shearing

Shearing is a mechanical process where a metal sheet is cut using two blades that move against each other. This method is used to cut straight lines or simple shapes in thin to medium-thickness metal. The shearing process is efficient and fast, making it ideal for cutting large quantities of material into smaller pieces.

Advantages of Shearing:

• Fast: Excellent for high-speed cutting of simple shapes.
• Economical: Requires less investment in equipment compared to laser or CNC machining.
• Minimal Tool Wear: The cutting blades do not undergo significant wear during operation.

Shearing is often used for cutting large sheets into smaller sections, and it is commonly applied in industries like construction and HVAC manufacturing.

• Bending and Folding

While not strictly a cutting method, bending and folding are essential processes that are often used in conjunction with cutting. These processes involve applying force to a metal sheet to create specific angles or shapes. Bending can be done using press brakes or roll forming machines, while folding is typically used for smaller bends or more complex shapes.

Advantages of Bending and Folding:

• Precision: Offers precise angle control for custom metal shapes.
• Flexibility: Can create a wide range of shapes and angles.
• Speed: Quick compared to more complex fabrication methods.

These methods are commonly used in industries like automotive manufacturing, where parts require specific bends or angles for structural integrity.

Key Considerations for Choosing a Custom Cut Metal Sheet​ Fabrication Partner

Selecting the right custom sheet metal fabrication partner is critical to the success of your project. The quality of the materials, precision of cuts, and speed of production can significantly impact both your product and your business operations. Here are key considerations to keep in mind when choosing a sheet metal fabrication partner:

• Experience and Expertise

A fabrication partner with years of experience in the industry is more likely to have the skills necessary to meet your unique needs. They should have a proven track record of delivering high-quality metal parts with the required precision and reliability. Look for a partner that specialises in the type of sheet metal work you need and has experience with the materials you require.

• Quality of Equipment

The quality of machinery and technology used by your fabrication partner plays a major role in the final product. Advanced equipment like high-powered lasers, CNC machines, and press brakes will ensure high-precision cuts, clean edges, and the ability to handle complex geometries. Choose a partner who uses state-of-the-art equipment to ensure your project is completed with minimal errors.

• Customisation and Flexibility

Custom sheet metal fabrication often involves creating parts tailored to specific dimensions or applications. The ideal partner should be able to offer a wide range of customisation options, including design flexibility, material choices, and surface treatments. Whether it’s intricate patterns or custom bends, they should be able to accommodate your needs with ease.

• Quality Assurance and Certification

Look for a partner that has a strong commitment to quality. Certifications such as ISO 9001:2015 or EN1090 indicate that the partner follows recognised quality management practices. This ensures consistency and reliability in the products they deliver. A quality assurance process should be in place to catch errors before the final product is delivered.

• Lead Times and Efficiency

Efficiency is key when it comes to custom fabrication, particularly if your project has tight deadlines. Discuss lead times upfront and ensure that your partner can deliver on time. A reliable fabrication partner will prioritise your deadlines and ensure the timely delivery of products without compromising quality.

• Cost and Value

While it’s important to consider cost, the cheapest option isn’t always the best. It’s crucial to balance cost with quality and precision. Look for a fabrication partner that offers competitive pricing but doesn’t compromise on quality. Be sure to get a detailed quote, including any additional charges for customisation, tooling, or surface treatments.

Applications of Custom Sheet Metal Cutting
