How Sheet Metal Fabrication Works?
Sheet metal fabrication involves a series of steps including material selection, design, cutting, forming, joining, machining, and finishing to transform flat metal sheets into complex and functional components. IDEAL managing each step and adhering to safety and quality standards, manufacturers can produce precise and durable parts for a wide range of applications. Here's a detailed overview of how sheet metal fabrication works:
Material Selection, Design & Planning
Metal Type: Choose the type of metal sheet based on the application and requirements. Common metals include steel, aluminum, stainless steel, copper, and brass.
Thickness and Gauge: Determine the thickness or gauge of the sheet metal, which affects the strength and flexibility of the finished product.
Blueprints and CAD Models: Develop detailed designs using computer-aided design (CAD) software. This ensures precision and accuracy in the fabrication process.
Cutting Patterns: Create cutting patterns or layouts to maximize material efficiency and minimize waste.
Cutting & Forming
Shearing: Straight-line cuts are made using a shear machine. This method is efficient for cutting large sheets into smaller pieces or basic shapes.
Laser Cutting: Uses a high-powered laser beam to make precise and complex cuts. Ideal for intricate designs and high precision.
Waterjet Cutting: Employs a high-pressure jet of water mixed with abrasives to cut through thick or sensitive materials without heat.
Plasma Cutting: Uses a plasma torch to cut through electrically conductive metals. Suitable for thicker sheets and less precision compared to laser cutting.
Bending: Changes the shape of the metal by bending it along a straight line using a press brake. This process creates angles or curves in the sheet.
Stamping: Uses dies and punches to shape or emboss the metal. This process is commonly used for high-volume production of parts with repeating features.
Deep Drawing: Involves drawing the metal into a die cavity to create deep or hollow shapes. Useful for making complex shapes with a single piece of metal.
Joining & Secondary Machining
Welding: Fuses metal pieces together by melting and re-solidifying them. Common welding methods include MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and spot welding.
Riveting: Joins metal parts by inserting and fastening rivets. Suitable for situations where welding is not practical.
Screws and Bolts: Mechanical fasteners used for assembling metal components, allowing for disassembly and adjustment.
Drilling: Creates holes in the sheet metal using drills or CNC machines. Essential for adding mounting points or other features.
Milling: Removes material from the sheet metal to shape or finish parts using a rotating cutter.
Deburring: Removes sharp edges or burrs left from cutting or machining processes to ensure safety and a smooth finish.
Grinding: Smoothens and refines surfaces or edges using abrasive wheels or belts.
Sanding and Polishing: Further smoothens and refines the surface to achieve a desired texture or shine.
Coating: Applies protective or decorative coatings such as powder coating, painting, or anodizing to enhance appearance and performance.

High Precision Tolerances: ±0.05 mm or even tighter can be achieved with advanced punching equipment and well-maintained tooling.
Bending
Bending is a manufacturing process used to shape metal or other materials into desired angles and curves by applying force. It's a fundamental technique in metalworking and fabrication, employed to create various components and products across industries.
Types of Bending
Air Bending: The bend angle is controlled by the depth of punch penetration and the material's springback. Suitable for a range of bend angles and radii.
Bottoming (or Coining): The punch makes complete contact with the die, reducing the impact of material springback. Provides high precision and consistent bend angles, ideal for complex and tight-radius bends.
Wipe Bending: The punch moves across the material's surface to create the bend. Useful for creating large-radius bends or bends in very thin materials.
Rotary Bending: Utilizes a rotating tool to bend the material around a set radius. Suitable for creating smooth, continuous bends in tubes and profiles.
Roll Bending: Involves passing the material through a set of rollers to achieve a curved shape. The rollers apply gradual pressure to create bends. Ideal for large-radius bends and cylindrical shapes.
Press Brake Bending: Uses a U-shape or V-shaped die and a punch to create bends. Commonly used for standard bends and provides good precision for a range of angles.
General Tolerances
Standard Tolerances: Ranges from ±0.5 mm to ±1.0 mm. Thicker and harder materials require more force and can be more challenging to bend precisely, and the tendency of the material to return slightly to its original shape after bending affects final tolerance
High Precision Tolerances: for critical applications the tolerance ranges from ±0.2 mm to ±0.5 mm. Tighter tolerances are achievable with advanced equipment and careful process control.
Stamping
Stamping is a versatile and efficient manufacturing process used to create a wide range of parts and components. With various techniques such as blanking, punching, embossing, and forming, stamping can handle diverse material types and produce high-precision, high-volume parts.

Sheet Metal Fabrication Tolerances
IDEAL produce high quality fabrications ranging from wall dispensers to radar housings; from protective covers to generator cabinets; from air conditioning housings to brackets. To maintain our high standard of quality we use the latest technologies including CNC Laser Cutting, CNC Punch machines, CNC Bending machines, Robot Welding, Automated and Manual Powder Coating lines, etc.
Experienced engineers and purchasing officers will know, however, that the tolerances specified in drawings have a direct correlation to the manufacturing price of the part or product. Unnecessary blanket tight tolerances on a drawing may well double or treble the manufacturing cost!
This is why we work to two or three different levels of tolerances so that purchasers can benefit from lower prices where looser tolerances permit. This does not mean a drop in quality - simply a broader tolerance where applicable and where specified by our customers. This is how the grades affect pricing:
Grade A - Tightest tolerances
- Higher scrap rate allowance
- Greater and more frequent QC inspections
- Better tooling and jigs
- More specialized QC equipment
Grade B - Standard tolerances
- Standard scrap rate
- Standard QA inspections
- Standard tooling
- Standard QC equipment
Grade C - Broader tolerances
- Low scrap rate allowances
- Random sample QC inspections
- Possible low cost tooling
- Limited QC equipment required
