Hardware processing refers to the processing of raw materials (stainless steel, copper, aluminum, iron) into various parts using machines such as lathes, milling machines, drilling machines, grinders, polishing machines, etc. according to customer drawings or samples, such as screws, motor shafts, model car parts, mobile power supply shells, etc. The subdivision of hardware surface processing can be divided into: hardware spray painting processing, electroplating, surface polishing processing, hardware corrosion processing, and so on. Polishing: The principle refers to achieving brightness and smoothness through regular dissolution; Method: By utilizing mechanical, chemical, or electrochemical effects, the surface roughness of the workpiece is reduced, resulting in a bright and flat surface through hardware processing. It is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.
The oxidation of hardware processing can be divided into hard aluminum oxidation, die-casting aluminum oxidation, color oxidation, aluminum anodizing, and natural color oxidation. Passivation: The principle can be explained by thin film theory. Passivation is the formation of a very thin, dense, well covered, and firmly adsorbed passivation film on the metal surface due to the interaction between metal and oxidizing substances. Compared with traditional physical sealing methods, passivation treatment has the characteristic of not increasing the thickness of the workpiece or changing the color, improving the precision and added value of the product, and making operation more convenient.
Back glue: Back glue is one of the important features of stamps. Machining: turning, planing, milling, grinding, rolling: The tooth uses two threaded rods to squeeze the workpiece being processed, causing the surface of the part to be pressed out of the thread. Tapping: Tapping is a die used to process or repair external threads. It has threads inside and can be manually processed or used on threading machines. Electroplating: Electroplating is divided into hanging plating, rolling plating, continuous plating, and brush plating, mainly related to the size and batch size of the parts to be plated.
