2.Electroplating: electroplating is also the most common hardware processing, to ensure that the product does not rusty, plating processing is commonly used on screws, stamping parts, battery pieces, car parts, small jewelry, etc.
3.Surface polishing processing: surface polishing processing is generally used in daily necessities.
4. Etching is the technique of removing material using a chemical reaction or physical impact. Etching techniques can be divided into two categories: wet etching and dry etching.It is also widely used in the processing of Weight Reduction instrument panels, nameplates and thin part that are difficult to process by traditional processing methods.
