koike nozzle tips offer the most accurate cuts among competitors:

Koike has a global reputation as a leader in the field of air gas cutting. A large part of Koike’s reputation is due to the high quality of its nozzle construction. Since a poor tip reduces the quality of the cutting nozzle performance, Koike has always been focused on research and development in the manufacture of this product. What sets Koike apart from its competitors is its commitment to research and development of cutting systems.

Koike customers have always benefited from the long history of air-gas cutting efficiency, research and development on torches, experience in cutting various materials and innovations such as the efficiency test machine of cutting nozzle tips. Koike has always been a support to its customers with the excellent performance of its nozzle tips. If you want your cutting to be done with the most precise standards and have an accurate, safe and economical cutting, Koike is the best choice for you.

High quality cutts

To ensure high quality of the cutting nozzle tip, koike checks the cutting surface and uses the following criteria to check the cutting quality level :

1. Smooth surface (minimum cut)
2. No high waste
3. The lowest rate of high surface melting
4. No bottom waste
In addition to the above criteria, the nozzle nozzle tips also meet the following conditions :
1. Maximum speed
2. Safe and stable operation
3. Economic consumption of gas fuel
To benefit from the above criteria and conditions, the nozzle tip of the coil must maintain a high and efficient oxygen flow and have a uniform heating flame. Note the small research :
1. Various shapes and sizes of oxygen cutting inlet tip
2. First, heat a mixture of oxygen and gas fuel in the pipes, the gas mixing chamber and the outlet.

As a result of this research, Koike developed a divergent nozzle tip. The output of the cutting machine also complements this divergent tip. This nozzle tip is the result of the engineering design of it’s extensive engineering department. Koike uses a proprietary stainless steel coating to ensure the strength of the nozzle tips. Thus, divergent tip technology has led to the production of bread-nozzle metal nozzle tips with small holes. Koike’s commitment to its research and design of air-cutting nozzles is clearly evident in the high quality of its final products.

nozzle tips increase the cutting security.

Since welding and cutting operations are likely to be damaged by explosions and other adverse events, the slightest flame and its reflection must be avoided. As a result, Koike is committed to ensuring the safety of cutting operations for its customers and to pay special attention to explosion prevention when designing cutting nozzle tips.

Explosions are divided into the following three categories:

1. Explosion: The initial heat flows backwards into the torch.
2. Flashback: The flame deflects to the edge of the nozzle tip.
3. Flashback resistance: The flame returns to the gas mixing point at the nozzle tip and melts it.

The most dangerous of these are flashbacks and flashback resistance. koike has solved these two problems through careful research and its design process. In the case of the flashback problem, the solution is to develop a fuel venturi effect on the nozzle tip. Medium and continuous pressure of the nozzle tip returns the heating oxygen flow to the gaseous fuel, so that the gaseous fuel enters the gas mixing point.

This creates a lot of problems for the flame itself as well as the product being cut. Flashback occurs during refueling. koike’s solution to this problem is to create a venturi effect on the cutting nozzle tip. This is done by high-speed heating oxygen. Gas fuel is sucked into the tip of the nozzle to prevent gases from mixing in the burner tube, thus preventing flashbacks during combustion.


Flashback resistance may occur when the nozzle tip is clogged with soot and ash during the cutting operation. Koike found that measuring the exact ratio of diameter to heating oxygen, gas fuel, and gas mixing chamber extinguishes the flame when the nozzle tip is blocked by soot. This also prevents flashback resistance.

Explosion prevention reflects Koike’s relentless efforts in research, performance and design to produce better products.
