F4 nozzles 6 mm and 8 mm. Application differences

[uncle_tyoma]

Hi everyone.

We usually use a 6 mm nozzle for F4. A nozzle with a diameter of 8 mm was obtained for the sample.

There was a question about using a nozzle with a diameter of 8 mm. For what applications is the 8mm nozzle in general? Maybe for some special materials? And in general, what are the features when using this nozzle? What is the application difference between 6 and 8 mm nozzles?

Grateful for any information.

The larger the nozzle diameter, the lower the speed and the higher the temperature of the particles. Thus, the 8mm nozzle is more suitable for powders with a high melting point and large particle size.

喷嘴直径越大，颗粒的速度越低，温度越高。因此，8mm喷嘴更适用于熔点高、粒径大的粉末。

Well Noted with thanks.
