We fabricate precision sheet metal enclosures, brackets and frames.

 One-stop manufacturing with CNC machining available.

Sheet metal fabrication is a cold forming process for thin metal sheets (typically ≤6 mm thick). Flat metal blanks are shaped into thin-wall structural components via cutting, bending, welding, riveting and other operations. The finished parts retain the original thickness of the raw sheet metal.

Thin metal sheets feature good ductility and can be processed by various techniques. Sheet metal processes fall into three main categories:

Laser cutting, punching and other methods are used to cut the blank profiles from metal sheets.

CNC bending forms flat metal sheets into required 3D shapes.

Welding, riveting, screwing to join sheet metal parts into finished assemblies.

We offer a full range of sheet metal cutting solutions, from intricate profiles to thick plate cutting to match your project requirements.

Laser cutting is a high-precision, efficient process for sheet metal fabrication. A high-power laser beam is focused down to a spot of approximately 0.001" (0.025 mm) to make clean, precise cuts on metal sheets.

The focal length ranges from 1.5"–3" (38–76 mm) with tight tolerance up to ±0.002" (0.05 mm) and narrow kerf width of 0.006"–0.015" (0.15–0.38 mm). It works great for complex geometries and fine details, though not ideal for extremely thick metal.

Advantages: High precision, low material waste, compatible with a wide range of metals.

Waterjet cutting is a cold cutting method that uses high-pressure water mixed with abrasives to erode and separate sheet metal. No heat distortion occurs during processing.

It can cut much thicker metal than laser cutting, with heat-affect-free edges without melting. Suitable for hard and heat-sensitive materials, also works for non-metals. The downside is slower cutting speed and higher equipment cost.

Advantages: No thermal distortion, capable of thick plates, works for both metals and non-metals.

Plasma cutting melts metal using high-temperature plasma arcs. It is a cost-effective solution for rapid cutting of thick metal plates.

It delivers fast cutting speed for conductive metals including carbon steel, stainless steel and aluminum. However, it creates a heat-affected zone with average accuracy and minor edge slag, not recommended for intricate precision parts.

Advantages: Fast cutting speed, low processing cost, ideal for rough cutting of thick metal.

With bending, stamping and metal spinning, we fabricate sheet metal parts from simple bends to complex curved surfaces. Supporting prototyping and mass production to ensure stable dimensional accuracy.

Bending uses press brake equipment to shape thin sheet metal into V-shaped, U-shaped or channel workpieces. The sheet is clamped and bent under pressure, with a maximum forming angle of 120°. Actual parameters vary according to sheet thickness and material tensile strength.

Metal springback is an inherent property. We adopt over-bending for angle compensation to ensure the formed dimensions meet design specifications.

Bending is the preferred forming solution for housings, brackets and structural sheet metal parts requiring stable angles and high repeatability.

Advantages: Cost-effective, stable performance in mass production, compatible with a wide range of metal materials.

Stamping uses press machines and precision dies to transform sheet metal into finished components quickly and accurately. The tooling defines the part shape, while stable pressure ensures uniform geometry from the first piece to the last.

This process is especially effective for high-volume production of flat parts, brackets, covers and structural sheets. It reduces manual work, shortens lead times and maintains tight repeatability.

Advantages: Fast production, reliable part-to-part consistency, cost-effective for large orders, compatible with various metal sheets.

Metal spinning fixes sheet metal onto the spindle of a spinning machine for high-speed rotation. Continuous pressure is applied by rollers to gradually fit the sheet to the die profile and form rotary curved workpieces. The whole part is integrally formed without welding seams.

Wall thickness and curved profiles can be precisely controlled by adjusting feed rate and rotational speed to reduce material waste.

Metal spinning is widely used to manufacture rotary sheet metal parts such as heads, cones, cylinders and curved housings.

Advantages: High structural strength of seamless one-piece parts, excellent surface finish, suitable for various complex curved rotary components.

Reliable Joining & Assembly for Sheet Metal Components

Our sheet metal assembly service integrates discrete sheet metal components into a fully functional end product. A wide range of joining methods are available, such as fastener assembly, welding and riveting.

Assembly operations take place after cutting, forming and surface finishing processes. Strict pre-assembly checks ensure all components meet tolerance requirements.

We provide assembly for enclosures, frames and mechanical housings, supporting sophisticated multi-part product designs.

Advantages: Turnkey finished assemblies, high design adaptability, manual and automated assembly options.

Welding is a metal joining process that fuses sheet metal components together at high temperatures to create durable, high-strength connections. It is widely adopted for structural frames and equipment enclosures.

Materials such as aluminum and stainless steel exhibit excellent weldability for thin metal work. We select proper welding methods including TIG, MIG and spot welding according to material grade, thickness and application requirements.

Welding operations are normally carried out after forming and before finishing machining to guarantee structural integrity and seamless assembly.

Advantages: High-strength joints, long-lasting connection, compatible with a wide range of metals.

Sheet metal fabrication processes metal sheets via cutting, bending and welding to produce custom metal parts. 

Our sheet metal components are widely used in many industries.
