What should I do if the metal parts are rusted?
Metal parts rust is a common occurrence during the use of the machine. If the rusted parts are not handled in time, it may affect the normal operation of the machine. However, for some relatively precise or irregularly shaped parts, if we use common rust removal methods, it may cause irreparable damage to the part. So is there a better way?
The blasting machine
has ideal rust removal
effect, fast speed and low cost. In addition, it can also prepare the surface for painting, spraying, electroplating and other processes. The blasted surface can be clean and have a certain roughness. Surface requirements to improve the bonding force between the cover and the workpiece.
The application scope of the blasting machine's rust removal technology is also relatively broad, mainly in the following aspects:
(1) Sand blasting for workpiece coating and pre-bonding of the workpiece can remove all dirt and other dirt on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called matte surface). By exchanging abrasives with different particle sizes, such as the abrasives of Feihan abrasives, to achieve different degrees of roughness, greatly improving the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality.
(II) Cleaning and polishing of the rough surface of the casting and the workpiece after heat treatment. Sand blasting can clean all dirt (such as oxide scale, oil stains and other residues) on the surface of the casting and forging, and the workpiece after heat treatment, and polish the workpiece surface to improve the finish , Can make the workpiece exposed to the uniform metal nature, make the appearance of the workpiece more beautiful and good-looking.
(3) Deburring and surface beautification of machined parts. Sand blasting 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 interface of the workpiece surface, making the workpiece more beautiful and more precise.
(4) Improve the mechanical properties of parts After sand blasting, mechanical parts can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing noise and increasing the service life of the machine.
(5) Light decoration effect For some special-purpose workpieces, sand blasting can realize different reflection or matt at will. Such as the grinding of stainless steel workpieces, plastics, polishing of jade, matt surface of wooden furniture, patterns on the surface of frosted glass, and the surface of the cloth.
