Wear Resistant Alumina Ceramic Nozzle
Alumina ceramic is a kind of alumina (Al2O3) ceramic material as the main body, for thick film integrated circuit.The alumina ceramic has good conductivity, mechanical strength and heat resistance.Note that with ultrasonic washing.Alumina ceramic is a kind of widely used ceramic, because of its superior performance, the application in the modern the society has been more and more widely, to meet the needs of daily and special performance.

Pressed Welded Steel Grating is made by the world first- class Italian ORSOGRIL equipment, which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance. Cross bar is pressed into the bearing bar by high tension resistance welding which is controlled by computer. So we can produce high quality gratings with firm welding, smooth surface and high strength.
Machines press-welded steel grid plates, as the name suggests, is the use of machine pressure welding lines for steel grid plate processing production, rather than artificial welding production, pressure welding steel grid plate bearing capacity is stronger. The advantages of steel grid welding are many, such as the flatness of the plate, the smaller error, the more precise size, and the faster production.
