[Trouble Resolution] This explains an efficient method for scale removal of fine parts.
The removal of black scale and heat treatment scale affects the corrosion resistance of the product and the finish of surface treatments such as plating. Generally, scale removal is performed using methods such as: - Shot blasting (for mass-produced items or large parts) - Grinding and polishing (for localized removal or small parts, in small quantities) - Chemical treatments such as pickling (regardless of quantity, size, or shape). Mechanical methods like shot blasting and grinding can be challenging for fine parts. Scale removal for fine parts is often done through chemical treatment; however, unlike mechanical methods that physically grind away the material, there may be residual strong scale or impurities left behind, which can result in an uneven finish in plating. Our "acid barrel polishing" combines the effects of chemical dissolution using acid and physical polishing through barrel polishing, making it a scale removal method suitable for fine parts. This method allows for efficient scale removal, burr removal, and pre-treatment for plating of fine parts, leading to a reduction in processing time. Prototyping is also possible, so please feel free to contact us.
