As a seasoned supplier of custom cut metal, I've witnessed firsthand the evolution of cutting technologies and their impact on the industry. Among the various methods available, waterjet cutting stands out as a versatile and efficient option. In this blog post, I'll compare waterjet cutting to other popular methods for custom cut metal, highlighting its advantages and limitations.
Waterjet Cutting: An Overview
Waterjet cutting is a non - thermal process that uses a high - pressure stream of water, often mixed with abrasive particles, to cut through various materials, including metals. The water is pressurized to extremely high levels, typically between 30,000 and 90,000 pounds per square inch (psi), and forced through a small nozzle. When abrasive is added, it enhances the cutting ability, allowing the waterjet to cut through even the toughest metals.
One of the key benefits of waterjet cutting is its precision. It can achieve tight tolerances, often within ±0.005 inches, making it ideal for creating complex and detailed parts. Additionally, since it is a non - thermal process, there is no heat - affected zone (HAZ), which means that the material properties of the metal remain unchanged. This is particularly important for metals that are sensitive to heat, such as certain alloys and stainless steels.
Comparison with Laser Cutting
Laser cutting is another widely used method for custom cut metal. It uses a high - powered laser beam to melt, burn, or vaporize the material. Laser Cut Stainless Steel Sheet is a popular product made through this process.
Speed
Laser cutting is generally faster than waterjet cutting, especially for thin materials. The laser beam can quickly slice through the metal, making it a great choice for high - volume production. However, as the thickness of the material increases, the cutting speed of the laser starts to decrease significantly. Waterjet cutting, on the other hand, can maintain a relatively consistent cutting speed regardless of the material thickness, although it is slower than laser cutting for thin metals.
Precision
Both waterjet and laser cutting can achieve high levels of precision. However, laser cutting can sometimes produce a slightly better edge finish on thin materials. The laser beam can create a very narrow kerf, resulting in a cleaner cut. But for thick materials, waterjet cutting may be more precise as it doesn't have the issues associated with the heat - affected zone that can distort the metal in laser cutting.
Material Compatibility
Laser cutting is more suitable for certain types of metals, such as carbon steel and aluminum. However, it may have limitations when cutting reflective materials like copper and brass, as the laser beam can be reflected, causing damage to the equipment. Waterjet cutting can cut through a wider range of materials, including reflective metals, composites, and even some non - metallic materials.
Comparison with CNC Sheet Metal Cutting
Cnc Sheet Metal Cutting is a subtractive manufacturing process that uses computer - numerical - control (CNC) machines to cut metal sheets.
Flexibility
Waterjet cutting offers greater flexibility in terms of the shapes and sizes of parts that can be cut. CNC machines are often limited by the size of the cutting tool and the machine's working envelope. Waterjet cutting can handle large - scale projects and can cut complex shapes without the need for special tooling.
Material Thickness
CNC sheet metal cutting is typically more suitable for thinner metal sheets. As the material thickness increases, the cutting force required by the CNC machine becomes a limiting factor. Waterjet cutting can cut through much thicker materials, up to several inches in some cases.
Cost
For small - scale production runs, CNC sheet metal cutting may be more cost - effective due to the lower initial setup costs. However, for large - scale or custom projects, waterjet cutting can be more economical in the long run as it doesn't require expensive tooling changes for different part designs.
Comparison with Laser Cutting of Tubes and Stamping Parts

Tube Cutting
When it comes to tube cutting, laser cutting can be very efficient for straight cuts and simple shapes. However, for complex tube geometries, such as curved cuts or cuts at odd angles, waterjet cutting is a better option. Waterjet cutting can easily adapt to different tube shapes and sizes without the need for extensive programming or special fixtures.
Stamping Parts
Stamping is a high - volume manufacturing process that is great for producing identical parts quickly. However, it is not suitable for custom or low - volume production. Waterjet cutting can create custom stamping parts with ease, allowing for quick prototyping and small - batch production.
Advantages of Waterjet Cutting in Custom Cut Metal
- Minimal Material Waste: Waterjet cutting has a relatively small kerf, which means less material is wasted during the cutting process. This is especially important for expensive metals.
- Environmentally Friendly: It is a clean and environmentally friendly process. There are no harmful emissions or chemicals involved, and the water used in the process can be recycled.
- Versatility: As mentioned earlier, waterjet cutting can cut through a wide range of materials, from soft plastics to hard metals, making it a one - stop solution for many custom cut metal needs.
Limitations of Waterjet Cutting
- Slower Cutting Speed: Compared to some other methods, especially for thin materials, waterjet cutting can be slower. This can be a drawback for high - volume production runs.
- Higher Initial Investment: The equipment for waterjet cutting is more expensive than some other cutting methods, and there are also ongoing costs for maintaining the high - pressure pumps and replacing the abrasive.
Conclusion
Waterjet cutting is a powerful and versatile method for custom cut metal. While it may not be the fastest or the cheapest option in every situation, it offers unique advantages in terms of precision, material compatibility, and flexibility. Whether you are working on a small - scale custom project or a large - scale industrial application, waterjet cutting should be considered as a viable option.
