Water Jet Glossary

We can provide the best products, services, and expertise for our customers.

Flow is a leading company in the development and manufacturing of ultra-high-pressure water jets and a top provider of robotics and assembly equipment. We offer environmentally friendly solutions through advanced technology to the manufacturing and industrial cleaning markets. In the early 1970s, the predecessor in charge of research and development became independent from Boeing and founded Flow Research. This marked the beginning of Flow. The ultra-high-pressure water jet, used as industrial cutting equipment, was our first product. Later, Flow invested in and patented the technology, successfully developing the world's first abrasive water jet capable of cutting hard materials up to 30.5 cm (12 in.) thick.

Significantly reduce processing time for complex shapes with high acceleration! Ultra-high pressure of the highest class at 600 MPa. A free booklet on acceleration is currently available!

When processing complex shapes with a water jet cutting machine, the entire processing procedure constantly repeats "acceleration ⇔ deceleration." In other words, it does not mean that cutting is always done at "maximum speed." ⇒ To shorten the cutting time of parts, it is necessary to focus on "acceleration"! Flow Japan's water jet cutting machine, the 'Mach 500/700 series,' can achieve an acceleration of 0.1 times, which is more than double that of other water jet systems, significantly reducing the time required for processing complex shapes. Furthermore, combined with a top-class ultra-powerful pump with a maximum operating pressure of 600 MPa, it enables high-speed and high-precision processing. It can easily cut materials over 100 mm thick and allows for adjustments to the cutting head and water flow to suit various materials, from soft to hard. ★ A pamphlet explaining the "Importance of Acceleration in Water Jet Cutting" is available for viewing via the "PDF Download" link below. ★ We have launched a YouTube channel!

A water jet cutting machine that achieves ultra-high pressure of 600 MPa! It can cut materials over 100 mm thick and is capable of handling difficult materials such as CFRP and titanium!

In metal material cutting, there are methods such as laser and plasma, but issues like "the occurrence of distortion due to heat" and "difficulty in processing hard-to-cut materials like CFRP" are common concerns. Additionally, wire electrical discharge machining is suitable for thick materials, but the issue of processing time is a concern. Flow Japan's water jet cutting machine, the 'Mach 500 Series,' is equipped with an industry-leading ultra-powerful pump that operates at a pressure of 600 MPa, achieving high-speed and high-precision processing. It can cut materials over 100 mm thick and allows for adjustments to the cutting head and water flow according to the material, from soft to hard (reducing processing time by up to 1/10). With water jet cutting, hard-to-cut materials like CFRP, titanium, and Inconel can be easily cut! ★ For a limited time, we are offering a handbook filled with comparison data between water jet cutting and other methods for free! ★ → For more details, please download the PDF data from the link below.

A water jet cutting machine that achieves ultra-high pressure of 600 MPa! Capable of cutting materials over 100 mm thick! Can process CFRP with high precision in a short time!

The advanced material "carbon fiber reinforced plastic: CFRP," which balances high strength and lightness, is widely used in the aerospace and automotive industries, but it is characterized by its difficulty in processing. Did you know that water jet cutting is often chosen for its trimming processing? With router processing, distortion due to heat occurs, leading to secondary processing, but water jet cutting eliminates this concern and allows for high-precision processing in a short time. When processing 10 meters of 25mm thick CFRP, it can be done in less than one-third of the time required by a router. 【Introducing our flagship model】 The Flow Japan water jet cutting machine 'Mach 500 Series' is equipped with an ultra-powerful pump with the industry's highest class operating pressure of 600 MPa, achieving high-speed and high-precision processing. It can cut materials over 100mm thick and allows for adjustments to the cutting head and water flow according to the material, from soft to hard (reducing processing time by up to 1/10). ★ We are currently offering a free technical document titled "Why Water Jet Cutting is Chosen for CFRP Processing?" ★ *Please download the PDF data from the link below to view it.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
