Sheet Metal Cutting

Sheet metal cutting is a subtractive manufacturing process, as it enables the production of usable parts by simply removing material. Manufacturers can employ various methods to cut sheet metal, including laser cutting, waterjet cutting, and plasma cutting.

Waterjet Cutting

CNC Laser Cutting

Laser cutting uses powerful lasers enhanced by lenses or mirrors. It’s a precise and energy-efficient machine suitable for thin or medium-sized metal sheets, though it may struggle to penetrate the hardest materials.

Waterjet Cutting

Waterjet cutting uses high-pressure water jets to cut metal. It’s particularly effective for cutting low-melting-point metal sheets, as they don’t generate heat that could potentially cause metal to deform excessively.

CNC Plasma Cutting

Plasma cutting creates an ionized gas electrical channel, forming a thermal plasma jet that can easily penetrate thick metal sheets. While not as precise as laser or waterjet cutting, it’s fast, powerful, and costs less.

Sheet Metal Welding

Common welding methods for sheet metal parts include argon arc welding, resistance spot welding, CO2 gas shielded welding, and manual arc welding. They each have different applications and limitations.

Gas Welding

Gas welding melts metal parts using a flame from burning gas. It’s commonly used for joining thin sheets of steel, cast iron repairs, and non-ferrous metals like copper and aluminum.

Laser Beam Welding

Laser beam welding melts metal parts using a focused laser beam. It’s great for small or hard-to-reach areas, but it’s not widely used because lasers are expensive and not very efficient.

MIG Welding

MIG welding uses gas to shield the welding area, ensuring a stable arc and consistent quality. It melts metal parts with arc heat and feeds in a welding wire to join them.

Plasma Arc Welding

Plasma arc welding uses a high-energy beam to weld metals like tungsten, molybdenum, copper, nickel, and titanium, which are difficult to melt or sensitive to heat.

Spot Welding

Spot welding uses electrodes to create weld spots between overlapping metal pieces. Pressure and electric current are applied to melt the metal, forming welds.

TIG Welding

Tungsten Inert Gas (TIG) welding, is the most commonly used method for welding stainless steel sheets ranging from 0.5mm to 4.0mm in thickness, whether manually or automatically.

Sheet Metal Forming

Sheet metal forming is the process of shaping metal sheets into the desired shapes using molds. This includes two methods: cold forming and hot forming. Cold forming is suitable for thinner sheets, while hot forming is typically used for thicker or more complex parts. Forming can be used to create curves, bent edges, and various convex and concave shapes.

Sheet Metal Bending

Sheet metal bending is the process of bending metal sheets to the desired angle or shape. This step typically requires specialized equipment known as a press brake.

Sheet Metal Rolling

Sheet metal rolling is a metalworking process that involves passing a sheet of metal through a series of rollers to reduce its thickness or change its shape.

Sheet Metal Stamping

Sheet metal stamping is a cold forming process widely used in the production of automotive components. However, for small-scale production, the cost of tooling is proportionally high.

Machining Standards

The mature standards of sheet metal processing serve as the constraints for the forming of sheet metal products. This design specification specifies the processing requirements for bending and welding, applicable to all sheet metal products designed and manufactured by our company.
