What is the industrial manufacturing method of aluminum powder?

Melt extrusion process

It is a method of hot extrusion of metal pigments and other components of powder coatings (resins, etc.) by screw extruder. Although metal pigments and powder coatings can mix well, the orientation of metal pigments in high viscosity melting is not sufficient. In addition, in the following crushing engineering, the destruction of the pigment sheet structure is inevitable. The metal powder made in this way is grey. Therefore, this method is only used for the manufacture of hammer powder.

Two dry

In this method, pulverized metal pigment powder is added to the pulverized powder coating and mixed with a mechanical mixer. The advantage of dry mixing method is that the metal pigment and powder coating are not very violent when mixing, so as to prevent the deformation of the metal pigment and not be affected by the metal. In addition, the Rose pigment/resin mixture also contributes greatly to the orientation of the metal pigments, improving the flash effect. The disadvantage of this method is that the shape, density and charge of metal pigment and resin powder particles will be very different when the powder is processed by automatic spray device.

A bonding process was used

In this method, the softening point of the resin is exceeded by drying and mixing metallic pigments and powder coatings and simultaneously heating them. At this time, the metal powder can be fixed and bonded on the surface of the resin powder by adding viscosity, which can prevent the stripping of the metal pigment and resin powder during the manufacturing process and after the recovery of the powder. That's a popular restraint.
