1) Chemical method:


Use pickling paste or spray to assist the re-passivation of the rusted parts to form a chromium oxide film to restore corrosion resistance. After pickling, in order to remove all contaminants and acid residues, it is very important to rinse with clean water. After all treatments, re-polishing with polishing equipment and sealing with polishing wax. For those with slight rust spots, you can also use 1:1 gasoline and engine oil mixture to wipe off the rust spots with a clean cloth.


2) Mechanical method:

Sandblasting, blasting with glass or ceramic particles, annihilation, brushing and polishing. It is possible to use mechanical methods to wipe off the contamination caused by the previously removed materials, polishing materials or oblique materials. All kinds of pollution, especially foreign iron particles, can become a source of corrosion, especially in humid environments. Therefore, mechanically cleaned surfaces should be properly cleaned in dry conditions. The use of mechanical methods can only clean the surface, and cannot change the corrosion resistance of the material itself. Therefore, it is recommended to re-polish with polishing equipment after mechanical cleaning and seal with polishing wax.


Investment Casting also to be called Precision Casting, lost wax casting, the material   including Stainless Steel, various alloy steel, carbonsteel, etc.
