Why Waterjet?

Services

EWL WaterJet operates a twin headed machine, with the capacity to cut sheets up to 3000mm x 2000mm x 200mm. To a tolerance of 0.2mm depending on material thickness.

We operate the latest CAD software to guarantee high accuracy profiles and the maximum utilization of material via nesting. We can work from your DXF or DWG files supplied, or alternatively we can produce drawings for your approval.

Material can be supplied free issue or alternately we can supply the material that meets your requirements.

EWL WaterJet also offers further services of CNC Bending, Welding and Fabrication, specialising in stainless steel and aluminium, please call us to discuss your requirements.

What is WaterJet?

At EWL WaterJet we operate two water cutting systems, “Pure Water” and “Abrasive”.

Pure Water – Is used on all soft materials such as foam, rubber and plastics, water is pressurised to approx 3600bar (52,000psi) and forced through a sapphire orifice creating a fine bead of water (0.1mm)

Abrasive – Garnet (very fine sand) is added to the pressurised water creating a Jet (1mm), abrasive water jet can cut through virtually any material.

Why WaterJet and not other cutting Methods?

Laser cutting and Plasma

  • The heat created during laser and plasma cutting changes the structure of the material e.g. Edges harden, stresses are formed and discolouration occurs.
  • The edge zone melts and burrs are formed.
  • Limitations on material thickness.
  • Limitations on hole sizes, generally holes can’t be smaller than the material thickness i.e. You can’t cut a 4mm hole in 5mm stainless steel.
  • Limitations on intricacy
  • Water Jet is a cold cutting process – edges don’t harden, stresses don’t form and there is no discolouration to the material.
  • No melting of material occurs, leaving crisp sharp corners and a burr free finish.
  • Water Jet has no restriction on hole sizes or intricate work.

Mechanical and Milling

  • Processes are usually time-intensive due to extensive removal of material = High costs
  • Removal of material = High waste
  • Intricate work is often not possible or so time intensive its not viable.
  • Water jet only removes the jets width of material (1mm), full removal of material is no longer required, saving time, material, and costs.
  • Water Jet is so accurate secondary processes aren’t usually required.
