What raw materials are used in the processing of hardware parts

Hardware Parts Processing is to process raw materials (stainless steel, copper, aluminum, iron.....) We use lathes, milling machines, drilling machines, grinding machines, polishing machines and other machinery to process various parts according to customers' drawings or samples, such as screws, motor shafts, model car parts, mobile power bank casings, etc. The surface processing of hardware can be further classified into: hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc.
Polishing: The principle refers to achieving a bright and smooth finish through regular dissolution. Method: A processing method that utilizes mechanical, chemical or electrochemical actions to reduce the surface roughness of the workpiece, thereby obtaining a bright and smooth surface. It is a finishing process carried out on the surface of the workpiece by using polishing tools, abrasive particles or other polishing media.
Oxidation can be classified into hard oxidation of aluminum, oxidation of die-cast aluminum, color oxidation, anodizing of aluminum, and natural color oxidation, etc.
Passivation in Hardware Parts Processing: The principle can be explained by the film theory. Passivation is due to the interaction between metals and oxidizing substances, during which a very thin, dense, well-covering, and firmly adsorbed passivation film is formed on the metal surface. Compared with the traditional physical sealing method, passivation treatment has the characteristics of absolutely not increasing the thickness of the workpiece and not changing the color, improving the precision and added value of the product, and making the operation more convenient.
Back adhesive: Back adhesive is one of the important features of stamps.
Machining: turning, planing, milling, grinding, hobbing: Hobbing uses two threaded rods to press the workpiece to be processed, creating threads on the surface of the part. Tapping: Tapping is also known as a die, which is used to process or repair external threads. It has threads inside and can be processed manually or used on a threading machine. Electroplating: Electroplating is divided into methods such as rack plating, barrel plating, continuous plating and brush plating, mainly related to the size and batch of the parts to be plated.
