The 9MB plasma spray gun is a versatile tool in the thermal spray industry, known for its high power and compatibility with various process gases such as argon, helium, hydrogen, and nitrogen. It comes in two variants: a machine-mounted version weighing 3.6 kilograms and a handheld version weighing 3 kilograms. The 9MB series, especially the Metco 9MB model provided by Oerlikon Metco, is renowned in the plasma spray gun category.

The common consumable parts for the 9MB plasma spray gun include electrodes and nozzles. Our company provides matching electrodes and various models of nozzles.

Structure of 9MB Tungsten Lined Plasma Spray Nozzles

The 9MB nozzle comes in two structures: one made of copper without tungsten inlay and another with tungsten. For the tungsten-containing nozzle, we can use the back-casting method. Although back-casting incurs higher costs, it results in a longer lifespan.

Advantages of Tungsten-lined 9MB Nozzle:

– Insert tungsten into the copper nozzle eliminate copper spitting.

– Tungsten has higher wear resistance than copper, performing better in the plasma arc. This helps control process deviations, extending the nozzle’s lifespan.

– The lifespan of tungsten-lined nozzles is longer than standard 9MB nozzles, reducing the need for gun maintenance.

– It reduces waste and the frequency of nozzle replacements.
