Now the atomization equipment is widly used to produced different metal powders, there are inert gas atomization, Close-coupled gas atomisation, water atomization, and EIGA gas atomization equipment for choose.
Inert gas atomisation
Non-ferrous metal powders are produced by a variety of means. The most significant of these is another atomising process, this time using an inert gas as the atomising fluid. In inert gas atomisation, the particle shape produced is dependent on the time available for surface tension to take effect on the molten droplets prior to solidification and, if a low heat capacity gas is used (nitrogen and argon are most common), this time is extended and spherical powder shapes result.
Spherical powders are particularly useful in hot isostatic pressing, where green strength is not an issue but initial packing density of the powder in the container is significant.
Close-coupled gas atomisation
The atomising nozzle design can provide either free-fall or close-coupled atomisation. In close-coupled (or confined) atomisation, the design of pouring nozzle and atomising head is adjusted so that impingement of the gas jets and molten stream occurs immediately below the exit of the nozzle with little or no free-fall height. This variant of atomisation technology has proved particularly useful for the production of fine powders for a range of applications, including Metal Injection Moulding.
Water atomisation
Driven by the trend towards higher density levels in PM structural parts as a means of increasing performance levels, sponge iron powders have been increasingly supplanted by powders made by water atomisation.
EIGA Titaninum Powder Gas atomization
The equipment adopts high pressure gas atomization method to make titanium powder and without crucible when melting. Powder has good spherical shape and high purity. The equipment is widely used in making 3D printing powder for aerospace, automobile, sea ship, medical, national defense industry and so on.
Our factory can provide all types metal powder atomization equipment, Small Lab type gas atomization equipment and Large capacity gas atomization equipment,VIGA gas atomization equipment and EIGA gas atomization equipment.
