7 Advantages of Waterjet Cutting

  • 2 min read

Waterjet cutting is a versatile cutting process that is used in the fabrication of a very wide variety of materials.

Waterjet cutting addresses material structure concerns such as heat sensitivity, porousness and 'reflectiveness' as well as cost and efficiency, as the technology used allows for very quick programming, setup and cutting times.
Pure waterjet cutting uses water compressed at a very high pressure which is then released through a narrow nozzle. The waterjet exits the nozzle at supersonic speeds of up to 850 m/s (sound travels at 350m/s) which is enough to erode materials with very high precision. This pure process is perfect for cutting soft, porous materials such as foam and rubber.

Abrasive waterjet cutting introduces an ‘abrasive’ into the waterjet and is used for cutting metal and harder materials.

Since waterjet cutting is a cold cutting process and therefore does not use heat, it doesn't change the structure of metal alloys. Plasma or laser cutting processes change the structure of materials through heat transfer and leave an inferior 'edge' when compared to waterjet cutting. Therefore, waterjet cutting can save customers time, energy and the cost of secondary operations associated with grinding or finishing of heat affected zones (HAZ).


  • Clean process
  • Water-only waterjet cutting is ideal for soft or delicate materials e.g. foam fabrication
  • Leaves the best edge
  • Reduced lead-time
  • Used with a wide variety of material densities, foam, rubber and metals
  • Cuts tapers and bevels easily
  • Cold cutting process that does not transfer heat or change structure of material

Foam Inserts

Waterjet foam fabrication offers an ideal solution in terms of its flexibility, speed and accuracy which is suited for a number of industries, including military, medical, music, film, electronics and automotive. Foam inserts protect the contents of a case, such as sensitive electronic components or military equipment, from being damaged when they come into contact with the case's interior. In addition to offering protection, foam inserts cut specifically to fit the contents of a case also make organizing and locating components much easier.
