What are the raw materials for hardware parts processing?

date：2023/08/18

Hardware parts processing is to process raw materials (stainless steel, copper, aluminum, iron...) into various parts according to customer drawings or samples with lathes, milling machines, drilling machines, grinders, polishing and other machinery, such as: Screws, motor shafts, model car parts, mobile power shells, etc. The subdivision of hardware surface processing can be divided into: hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing and so on.
Polishing: The principle is to achieve brightness and smoothness through regular dissolution; Method: Use mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.

Hardware parts processing
The oxidation is divided into aluminum hard oxidation, die-cast aluminum oxidation, color oxidation, aluminum anodic oxidation, natural color oxidation and so on.
Metal parts processing passivation: The principle can be explained by film theory. Passivation is due to the action of metal and oxidizing substances. When it acts, a very thin, dense, good covering performance is formed on the metal surface, and it is firmly adsorbed on the metal. Passivation film on the surface. Compared with the traditional physical sealing method, the passivation treatment has the characteristics of absolutely no increase in the thickness of the workpiece and no change in color, which improves the precision and added value of the product and makes the operation more convenient;
Adhesive: Adhesive is one of the important features of stamps.
Machining: turning, planing, milling, grinding, rolling: teeth use two threaded sticks to squeeze the workpiece, so that the surface of the part is pressed out of the thread. Tapping: Tapping is a die, which is used to process or repair external threads. There are threads inside. It can be processed manually or used on threading machines. Electroplating: Electroplating is divided into rack plating, barrel plating, continuous plating and brush plating, which are mainly related to the size and batch of parts to be plated.
