▣ Water - Jet

#Justice

⁠Waterjet is a technology developed to cut materials for the coal industry, construction, and building, and cuts objects by applying water and abrasives to the pressure discharged from the ultra-high pressure generator.

At present, we are applying to various fields such as cutting and cleaning in semiconductor, aviation, ship, general machinery industry with steady technology development.

# Waterjet Principles

It is a technology that cuts the material by using physical force and friction force using high speed energy of 1,000m per second by spraying it through a micro nozzle of 1mm diameter using an ultra high pressure pump that produces water pressure up to 4,000BAR.

# Characteristic

- It is a new technology of construction method that is completely different from the existing cutting method. High energy. Ultra-high pressure processing eliminates deformation, residual stress, microcracking and chemical deformation of the substrate.

- It is easy to cut the material which was difficult or weak by the existing cutting method and can obtain the excellent quality. Unaffected by the shape, the design is free and suitable for cutting complex products.

- Cutting surface is excellent in roughness and quality, which reduces post-processing time.

- It is suitable for cutting products with explosive, oxidizing and volatility because cutting using water.

- As an environment-friendly technology, dust and harmful gas do not develop during operation, and it can compensate for the shortcomings of conventional equipment and ensure user safety.

# Waterjet Job Types
