How to choose the ceramic ring for the fiber laser cutting machine?

The ceramic ring is an important part of the cutting head of the laser cutting machine. Its main function is to transmit the electrical signals collected by the laser head nozzle, which plays an important role in the normal and stable operation of the laser cutting machine.

We often encounter equipment shutdowns for no reason, laser heads hitting the working surface and other failures that are actually caused by instability because of poor laser ceramic rings. So it is very important to choose a high-quality laser ceramic ring for the laser cutting machine.

Here is how to choose a high-quality laser ceramic ring.

The laser ceramic ring composes of a ceramic body, stainless steel parts, and copper needles. The ceramic body is mainly used to maintain the insulation of the laser head body. The stainless steel part is used to ensure sufficient contact with the nozzle, so transmitting electrical signals to the copper needles. After a certain period of use, the old laser ceramic rings in the market often have poor contact between the stainless steel parts and the copper needles, and the copper needles may break in severe cases, resulting in unstable signals, or even no signals, so the laser cutting machine stops for no reason cause losses to the user. High-quality stainless steel parts, after being assembled with ceramic bodies of appropriate size, can ensure good concentricity. So the laser cutting machine can reduce the concentricity error between the two when replacing the nozzle. It can greatly reduce the loss of working hours and greatly improve the working efficiency of the laser cutting machine! If you are interested in our laser welding machine.

Boron Nitride Nozzle For Molten Metal Atomizing

BN is a material with the non-wet feature. So molten metal won’t be stuck onto the nozzle. Additionally, Boron Nitride ceramic is a kind of refractory ceramic with low expansion and high thermal conductivity. These features make it to be an ideal choice for atomizing nozzles. It’s very easy to be machined to custom design with precision and tight tolerance because of its machinability.

Boron nitride can be long-term used at 1800 degrees under a vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100 °C. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperatures.

Alumina Mo-Mn Metallization Method

What is Mo-Mn Metallization?

The metalized layer is obtained by adding a small amount of MoMn powder and coating it on the surface of the ceramic body with a binder and sintering at high temperatures.

Features:
1) High-intensity sealing, high air-tightness, high reliability, good heat resistance
2) Excellent insulation performance and high temperature resistance
3) Good mechanical, electrical, and thermal conductivity
4) Great bonding strength
5) Widely used for all electric products and electric heating products

These metalized ceramics are ideal for high voltage, high vacuum, and high pressure applications.

So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing. A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that has a different coefficient of thermal expansion.

A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering.

The metalized surface receives a secondary coating of nickel to seal and improve wettability for later brazing.

Applications:
Electrical transmission and distribution
Electronics industry
Textile machinery
Defense
Medical electronics
Automobile industry
Sealing
Solid Oxide Fuel Cells
High temperature application

We can supply the products according to the customer’s drawings, samples, and performance requirements.

Whether the ceramic electric heating tube will leak during the heating process?

In our daily life, we often encounter the application scenario of liquid heating, and there are various types of heating elements in the process of choosing, with different performance and advantages. Here focus and talk about the ceramic heating tube in the process of water heating whether the fracture will continue to lead to electricity leakage such an unsafe phenomenon.

Ceramic heating tube is made of alumina flow-casting porcelain as insulation layer and substrate, and high temperature metal thick film paste is printed on the raw porcelain side, and then rolled, sintered at high temperature in hydrogen furnace to become a heating element, and finally welded leads to form MCH heating element. Accordingly, besides lead outside, the calorific area of the tube is complete insulation, this contacts to the home appliance with water, if regard water heater as, having an outstanding advantage, the safe problem is ensured.

However, the ceramic heating tube is more fragile than other materials, easy to fracture by a violent impact. Therefore, many customers are worried about whether there will be electric leakage and other unsafe phenomena after ceramic pipe fracture. Do not worry, because of the particularity of the ceramic electric heating tube heating line, after the fracture of the electric heating tube, it will immediately stop the power operation, can completely avoid leakage and other safety hazards, which is more conducive to the application of water heating.

In addition, the ceramic heating tube has another advantage compared with other heating materials, that is, it can effectively reduce the residual scale when water heating. Many water heating products, such as electric kettles and cups, are plagued by scale problems. If metal is used as the heating element, the residue of scale will directly affect the function of the metal tube, life and so on.
