Sheet Metal Fabrication Services
Sheet metal fabrication turns flat metal sheets into functional parts using cutting, bending, and forming processes. It's fast, versatile, and great for brackets, housings, enclosures, and structural components. Whether you need prototypes or production volumes, sheet metal offers strength, durability, and excellent turnaround times for industrial and consumer products.
Comprehensive machining services for any complexity
Laser Cutting
Laser cutting is a precise, high-speed method for cutting metal sheets using a concentrated beam of light. It delivers clean edges, tight kerf widths and minimal distortion, making it suitable for both prototype and production components. Standard tolerances typically fall around ±0.2 mm, while precision suppliers can maintain ±0.1 mm depending on material thickness and geometry. Laser cutting is commonly used for enclosures, brackets, chassis parts, mounting plates, and any flat components that require accurate profiles with sharp internal features.
Bending / Press Brake Forming
Sheet metal bending uses controlled force to create angles, flanges and formed features in metal sheets. Accuracy depends on material thickness, grain direction and tooling selection, with standard bend tolerances around ±1° for angle accuracy and ±0.5 mm for bend location, while precision shops can achieve ±0.25 mm with the right tooling and setup. Bending is typically used to produce structural brackets, folded enclosures, battery trays, mechanical covers, U-channels, and a wide range of formed components used in assemblies and mechanical housings.
Punching (CNC Turret Punching)
CNC punching uses a computer-controlled turret and tooling set to create holes, slots, louvers and simple forms at high speed. It is efficient for medium-to-high volume parts with repeated features and offers standard tolerances of ±0.2-0.3 mm, with precision reaching ±0.1-0.15 mm depending on tooling quality. Punching is commonly used for ventilation panels, control boxes, chassis parts, mounting plates and components that benefit from fast, repeatable hole or feature creation across larger batches.
Sheet Metal (TIG, MIG, Spot Welding)
Sheet metal welding joins individual laser-cut or formed components into assemblies using TIG, MIG or spot welding methods. Dimensional accuracy depends on fixturing, heat input and part geometry, with standard welded assemblies holding ±0.5-1.0 mm, while precision jig-based welding can achieve ±0.25-0.5 mm. This process is widely used for frames, brackets, enclosures, mechanical assemblies, battery housings and structural components that require strength and permanence rather than removable fastenings.
Sheet Metal Stamping
Stamping is a high-speed forming and cutting process that uses dedicated dies to shape metal sheets into precise, repeatable components. It is best suited for medium to high-volume production where repeatability, cycle time and per-unit cost are critical. Standard stamping tolerances typically fall around ±0.1-0.2 mm, while fine-blanking or precision tooling can achieve ±0.05 mm on critical features. Stamping is widely used for brackets, clips, shields, terminals, enclosures, and structural components that require consistent geometry across large production runs.
Waterjet & Plasma Cutting
Waterjet and plasma cutting are high-efficiency methods for processing sheet and plate materials, chosen based on thickness, edge requirements and cost targets. Waterjet cutting uses a high-pressure water and abrasive stream to produce accurate profiles without heat, avoiding distortion and preserving material properties - typically achieving ±0.2-0.3 mm, with precision systems reaching ±0.1-0.15 mm. Plasma cutting, by contrast, uses an ionised gas jet to cut thicker metals quickly and cost-effectively, with standard tolerances around ±0.5-1.0 mm and high-definition systems achieving ±0.3-0.5 mm. Together, these processes are used for structural plates, heavy-gauge brackets, industrial frames, machinery components and any application where material thickness or thermal considerations dictate the cutting method.
