●On material, we do not use recycled crushed alloy powder. Stable material chemical composition to make sure each nozzle quality is stable.
●On manufacturing, compression moulding technology to make sure compact texture with minimum and smallest porosity.
●On sintering, more than 20 hours process from heating to cooling and well-controlled sintering equipment to guarantee nozzle hardness and strength.
●On structure designing, we optimize structure parameter to achieve even wearing during sandblasting which fully increase nozzle life.
