Sheet Metal Fabrication | Laser Cutting & Bending

Sheet Metal Fabrication Overview

Sheet metal fabrication encompasses a broad range of manufacturing processes used to transform flat metal sheets into finished parts and structures. The primary processes include cutting (laser, waterjet, plasma, and punching), bending (CNC press brakes), forming (stamping, deep drawing, and rolling), joining (welding, riveting, and fastening), and finishing (painting, plating, and coating). These processes can be combined in virtually unlimited ways to create parts ranging from simple brackets to complex enclosures and structural assemblies.

Modern sheet metal fabrication has been revolutionized by CNC technology and fiber laser cutting. Today's CNC-controlled equipment offers unprecedented precision, repeatability, and speed compared to manual methods. Fiber laser cutting, in particular, has become the dominant cutting technology due to its exceptional speed, precision, and ability to cut a wide range of metals and thicknesses with minimal heat-affected zones. At Swifab, we leverage these advanced technologies to deliver parts that meet the most demanding specifications.

Our sheet metal fabrication capabilities are complemented by our in-house CNC machining, 3D printing, and injection molding services, making Swifab a true one-stop manufacturing partner. This integrated approach eliminates the need to coordinate with multiple vendors, reduces lead times, and ensures consistent quality across all processes. Whether your project requires sheet metal parts alone or a combination of manufacturing methods, we have the equipment and expertise to deliver.

Laser Cutting Services

Swifab's laser cutting services utilize state-of-the-art fiber laser systems capable of cutting steel up to 25mm thick, stainless steel up to 20mm, and aluminum up to 16mm. Our laser cutting machines feature power outputs ranging from 2kW to 12kW, allowing us to optimize cutting parameters for each material and thickness combination. The cutting accuracy of our laser systems is +/-0.05mm, with edge quality that typically requires no secondary finishing for most applications.

Our fiber laser cutting systems offer several key advantages over traditional CO2 laser and plasma cutting. Fiber lasers provide significantly faster cutting speeds — up to 5 times faster for thin materials — with lower operating costs and reduced maintenance requirements. The smaller focused spot size enables finer detail cutting and tighter corner radii, while the lower heat input minimizes thermal distortion and the heat-affected zone (HAZ). This is particularly important for thin materials and precision applications where warping must be avoided.

We maintain a comprehensive inventory of sheet metal materials in standard sizes (1220mm x 2440mm, 1500mm x 3000mm, and 2000mm x 4000mm) for immediate processing. Our laser cutting capacity handles both single-piece prototype orders and high-volume production runs with equal efficiency. We also offer nesting optimization services to maximize material utilization and minimize waste, reducing both cost and environmental impact.

CNC Bending Services

Swifab's CNC bending services use advanced CNC press brakes with tonnage capacities up to 300 tons and bending lengths up to 3000mm x 15mm thickness. Our press brakes are equipped with CNC back gauges, multi-axis crowning systems, and precision tooling that enables us to achieve bending accuracy of +/-0.5mm on standard parts and +/-0.2mm on precision applications. We maintain an extensive tooling library with over 500 sets of punch and die combinations to accommodate virtually any bend profile.

Our CNC bending capabilities cover the full range of bending operations, including air bending, bottom bending, coining, and three-point bending. Air bending is the most common method, offering flexibility in bend angles without tooling changes. Bottom bending and coining provide higher precision for critical applications. We also perform complex sequential bending operations for multi-bend parts, box formations, and channel profiles, with our CNC systems ensuring consistent repeatability across production runs.

Critical considerations for CNC bending include minimum bend radius (determined by material type and thickness), bend allowance calculations, K-factor compensation, and springback compensation. Our engineering team performs detailed bend analysis on every part before production, providing DFM feedback and recommending design modifications to optimize manufacturability. We also handle flange height limitations, hole-to-bend distances, and relief cut requirements to ensure clean, accurate bends every time.

Punching & Forming Services

In addition to laser cutting, Swifab offers CNC punching services using high-speed turret punch presses capable of processing sheet metal up to 3mm thick with punching speeds up to 1,000 hits per minute. CNC punching is particularly cost-effective for parts with many holes, standard shapes, and repetitive features. Our punching machines can perform a wide range of operations including punching, notching, nibbling, louvers, embossing, countersinking, and tapping — all in a single setup.

Our forming capabilities extend beyond simple bending to include stamping, deep drawing, rolling, and specialized forming operations. We operate hydraulic presses up to 500 tons for stamping and deep drawing operations, capable of forming parts from sheet metal up to 6mm thick. Rolling services handle cylindrical and conical shapes with diameters up to 2000mm. We also perform corrugation, beading, flanging, and hemming operations to create complex formed geometries.

For high-volume production, we design and build custom stamping dies and progressive dies that enable rapid, consistent part production. Our tooling design team uses advanced simulation software to optimize die design, predict material behavior, and minimize development time. Whether you need a few hundred parts with a simple die or millions of parts with a progressive die, our stamping capabilities deliver the efficiency and consistency your production requires.

Surface Finishing for Sheet Metal

Swifab provides a comprehensive range of surface finishing services specifically tailored for sheet metal parts. Our finishing capabilities include powder coating in any RAL or Pantone color with thicknesses from 60 to 120 micrometers, liquid painting (including anti-corrosion primers and topcoats), anodizing for aluminum parts (Type II decorative and Type III hard coat), plating (zinc, nickel, chrome, and electroless nickel), and passivation for stainless steel components.

For decorative and consumer-facing applications, we offer brushed finishing, mirror polishing, bead blasting, and vibration finishing to achieve specific surface textures and appearances. We also provide silk screening, pad printing, and laser marking for permanent labeling, branding, and regulatory markings. Our finishing team understands the unique requirements of sheet metal finishing, including proper pre-treatment (degreasing, phosphating, chromating), edge and corner coverage, and the impact of forming operations on coating adhesion.

Quality control for finishing includes thickness measurement, adhesion testing (cross-hatch and pull-off), salt spray testing for corrosion resistance, color matching under standardized lighting conditions, and visual inspection for defects. We can meet specific finishing standards including ASTM, ISO, and automotive OEM specifications. Our finishing line capacity supports both small batch and high-volume production with consistent quality and turnaround times.

Materials for Sheet Metal Fabrication

Swifab processes an extensive range of sheet metal materials to meet diverse application requirements. Our steel capabilities include cold-rolled steel (SPCC, DC01), hot-rolled steel, galvanized steel (SGCC, DX51D+Z), galvannealed steel, and electro-galvanized steel in thicknesses from 0.5mm to 25mm. Our aluminum offerings include 1050, 3003, 5052, 5083, and 6061 alloys in thicknesses from 0.3mm to 16mm, available in various tempers (H14, H24, H32, T6).

Our stainless steel range covers 304, 304L, 316, 316L, 430, and 201 grades in thicknesses from 0.3mm to 20mm, with surface finishes including 2B, BA, No.4 (brushed), and mirror. We also process copper (C1100), brass (C2680, C2801), and specialty materials including titanium sheet, carbon fiber sheet, and pre-painted/coated metals. For electrical applications, we offer silicon steel and aluminum-magnesium alloy sheets.

We maintain a well-stocked inventory of the most commonly used sheet metal materials in standard sizes and thicknesses, enabling immediate production for most orders. For specialty materials, specific grades, or non-standard sizes, our established supply chain network ensures quick sourcing at competitive prices. Our material sourcing team can also provide mill test certificates (MTC) and material certifications for quality-critical applications.

Design Considerations for Sheet Metal

Optimizing your design for sheet metal fabrication can significantly improve part quality, reduce manufacturing costs, and shorten lead times. Key design considerations include selecting appropriate material thickness (avoiding unnecessary thickness increases that add weight and cost), designing bend reliefs to prevent tearing at bend intersections, maintaining adequate flange heights (minimum 3-4 times material thickness), and ensuring sufficient distance between holes and bend lines (minimum 2.5 times material thickness plus bend radius).

For laser-cut parts, we recommend minimum hole diameters of 1.0mm (or equal to material thickness for thicker materials), minimum slot widths of 1.0mm, and minimum feature sizes that account for the laser kerf width (typically 0.1-0.3mm). Corner radii should be designed to match available tooling — sharp internal corners are not achievable with laser cutting and require small radii. For bent parts, we recommend designing with standard bend radii where possible and avoiding bends too close to existing features.

Our engineering team provides detailed DFM analysis for every sheet metal project before production begins. We review your designs for manufacturability, identify potential issues, and recommend optimizations that can reduce cost without compromising functionality. This service is provided at no additional charge and has helped many clients reduce their manufacturing costs by 20-40% through smart design improvements.
