Minimum lifespan of Sunstart nozzle: 90-100 hours
With the same performance with Roctec, but the price is much cheaper than that of Roctec.
Sunstart can send you some sample for free test.

Sunstart nozzle' s material which from the begainning of the basic power to the last pressing gets a completely patent process. The nozzles is not only made by the NANO tungsten carbide granule, making it have a better wear resistance, but also with a surpass the other normally tungsten carbide nozzle.
The main reason that changed wear resistance of tungsten carbide is the content percent of
Binder. To strive for more hardness tungsten carbide and more wear resistance material, the key way is try to decrease the content of binder and increase the density content. To maintain the hardness of the tungsten carbide, and meanwhile to make sure using Min binder is the most important surmount.
