What are the manufacturing processes of hardware accessories?

Hardware: traditional hardware products, also known as “hardware”. It refers to the five metals of gold, silver, copper, iron and tin. Manual processing can be used to make knives, swords and other works of art or metal devices. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, building hardware and security products.
Metal processing can also be called metal processing. Milling, milling, boring and so on, modern processing has increased discharge machining. In addition, die casting and forging are also common processing methods. If only the sheet metal is involved, then milling, grinding, wire cutting (discharge type) and heat treatment are often used.

Hardware processing can be divided into: automatic lathe processing, CNC processing, CNC lathe processing, five axis lathe processing, according to roughly divided into: hardware surface processing, hardware molding processing two categories.
1. Hardware surface processing subdivision can be divided into: metal spray painting process, electroplating, surface polishing process, metal corrosion processing and so on.
1, spray painting processing: at present, the hardware factory in the production of large pieces of hardware products when the use of paint processing, through the spray paint processing to avoid rusting hardware, such as: daily necessities, electrical housing, handicrafts and so on.
2, electroplating: electroplating is also the most common processing technology of hardware processing, through the modern technology technology to the metal surface electroplating, to ensure that the products are used for a long time without mouldy embroidery, electroplating processing is common: screws, stamping parts, battery pieces, car parts, small ornaments and so on.
3, surface polishing processing: the surface polishing process is generally used in daily necessities, through the surface burr treatment of hardware products, the edge corner sharp part is thrown into the smooth face, so that in the process of use, it will not cause harm to the human body.
Two. Metal forming processes mainly include die casting (die casting, cold pressing and hot pressing), stamping, sand casting, and mold casting.
