Water jet cutting is a highly precise, environmentally friendly cutting method that uses a high-pressure stream of water—often combined with an abrasive—to slice through a wide range of materials with exceptional accuracy. It is widely used across manufacturing, mining, fabrication, aerospace, and engineering industries where clean edges, minimal heat distortion, and material versatility are essential. Tecpro Australia supplies specialised nozzles, orifices and high-pressure components designed for reliable performance in demanding water jet cutting applications.

What Is Water Jet Cutting?

Water jet cutting uses extremely high-pressure water—typically between 30,000 and 90,000 psi—to deliver a focused jet capable of cutting materials cleanly and efficiently. Two main methods are used:

Pure Water Cutting

A narrow, ultra-high-pressure water stream is used to cut softer materials such as:

• Rubber

• Plastics

• Foam

• Food products

• Paper and packaging materials

Abrasive Jet Cutting

Garnet or another fine abrasive is added to the water stream to cut harder materials including:

• Stainless steel

• Aluminium

• Stone and tiles

• Glass

• Composites

• Hardened steel

• Ceramics

Both systems rely on high-quality nozzles and orifices to maintain a consistent, accurate cutting stream.

Advantages of Water Jet Cutting

Water jet technology offers several key benefits over other cutting methods such as plasma, laser or mechanical cutting:

• No heat-affected zone (HAZ) – maintains material strength and integrity

• Virtually no mechanical stress on the workpiece

• Highly accurate cuts with tight tolerances

• Extremely versatile – cuts almost any material

• Smooth, clean edges that often require no secondary finishing

• Environmentally friendly – no toxic fumes, minimal waste

• Efficient nesting reduces material waste

These advantages make water jet cutting ideal for precision fabrication and high-value materials.

High-Pressure Nozzles & Orifices for Water Jet Cutting

At the heart of every water jet cutting system is the nozzle assembly. Tecpro supplies a range of components designed for long service life and consistent cutting quality:

• Sapphire, diamond and carbide orifices for ultra-fine water streams

• High-pressure cutting nozzles for pure and abrasive jets

• Mixing tubes engineered for uniform abrasive flow

• Stainless steel nozzle bodies for durability under extreme pressure

• Wear-resistant components that maintain performance over extended operating hours

Correct nozzle selection ensures maximum cutting speed, accuracy and operational efficiency.

Applications Across Industry

Water jet cutting is used across a wide range of sectors, including:

• Metal fabrication and engineering workshops

• Mining and quarrying equipment manufacturing

• Aerospace and defence components

• Automotive and transport

• Food processing (pure water jets)

• Stone, tile and glass cutting

• Custom fabrication and prototyping

• Electronics and precision machining

Its versatility makes it a preferred cutting method for both small workshops and large industrial facilities.
