What should I do if the metal parts are rusted?

Rusting of metal parts is a common occurrence during machine use. If the rusted parts are not handled in time, it may affect the normal operation of the machine. However, for some relatively precise parts or some parts with irregular shapes, if we use the commonly used rust removal method, it may cause irreparable damage to the parts. So is there a better way to handle it?
The sandblasting machine has ideal rust removal effect, high speed and low cost; in addition, it can also prepare the surface for painting, spraying, electroplating and other processes, and the sandblasted surface can be clean and have a certain roughness. Surface requirements, thereby improving the bonding force between the cover layer and the workpiece.

The application range of the sandblasting machine derusting process is also relatively wide, mainly in the following aspects:

(1) The coating of the workpiece and the sandblasting before the workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic schema (the so-called rough surface) on the surface of the workpiece, and can By exchanging abrasives with different particle sizes, for example, the abrasives of Feizhan abrasives can achieve different degrees of roughness, which greatly improves the bonding force between the workpiece and the paint and plating. Or make the bonding parts more firm and better in quality.

(2) Cleaning and polishing of rough surfaces of castings and workpieces after heat treatment Sandblasting can clean all contaminants (such as oxide scale, oil and other residues) on the surfaces of castings and forgings and workpieces after heat treatment, and polish the surface of workpieces to improve the smoothness of workpieces , can make the workpiece reveal a uniform and consistent metal color, so that the appearance of the workpiece is more beautiful and good-looking.

(3) Burr cleaning and surface beautification of machined parts Sandblasting can clean the tiny burrs on the surface of the workpiece, make the surface of the workpiece more flat, eliminate the harm of burrs, and improve the grade of the workpiece. And sandblasting can make small rounded corners at the junction of the workpiece surface, making the workpiece more beautiful and more precise.

(4) Improve the mechanical properties of the parts. After sandblasting, the mechanical parts can produce uniform and fine concave and convex surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing noise and improving the service life of the machine.

(5) Lighting effect For some special-purpose workpieces, sandblasting can achieve different reflections or matts at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade articles, the mattization of the surface of wooden furniture, the pattern of frosted glass surfaces, and the textured processing of cloth surfaces.
