Surface preparation is the process of manually forming a surface layer on the surface of the matrix material with different mechanical, physical and chemical properties.The purpose of surface preparation is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions.For metal castings, we compare the commonly used methods of surface preparation, mechanical polishing, chemical processing, heat treatment, surface coating surface, surface preparation is carried out on the workpiece surface cleaning, cleaning, deburring, to oil, scale, etc.
Steel shot and steel grit etc are the good processing materials for surface preparation. Speically for metal surface or steel surface,like steel plate,steel sheet, steel structure etc. Before those steel parts, workpieces painting, plating etc, must use steel shot or steel grit for blasting to remove dust,deburring etc. Use correct sizes of shot materials, you can be ensure to get the best treat results, SA2.5, SA3.0 etc. Frandcom industrial limited use good cast steel materials and alloy steel materials to make blasting medias, all types and all sizes availble, like steel shot S70 to S1110, steel grit G10 to G120 etc. For hardness and sizes etc, we accept OEM production.
