Hardware processing includes many different types, such as shells, daily use, screws and other commonly used parts, and accessories are also classified into many categories. It depends on the product, so which type of accessories processing belongs to? Let's introduce the categories below.
Hardware parts processing can be processed by stamping dies after selection, and the manufactured mold shells can be processed by high-speed punching machines for cold stamping, and sheet metal processing is carried out first and second, that is, most of the processed material images are sheet metal, and the processing efficiency is relatively high, which is suitable for large quantities. mass production. The processing technology is divided into engineering molds and continuous molds. Engineering molds are also called single stamping molds. Many units are separated in one mold, and one stroke processed by such a high-speed punching machine is a finished product. The high-speed continuous high-speed punch can process three or four hundred materials per minute.
Generally speaking, it can be divided into two categories, forging and finishing. There are actually turning, milling, planing, grinding, pliers, stamping dies, forging and other methods. The metal processing step is to cut materials according to the production needs. After the production of some small parts such as small parts, they can be processed by high-speed punching machines and then processed by gong cutting or CNC processing. This is very common in the production of glasses parts and car parts. And to make shipping containers: it is to carry out welding after the material cutting high-speed punching machine, then carry out the sand blasting and carry out the oil pump, and then install the accessories before delivery. For small hardware accessories, a lot of polished metal surface treatment, electroplating or oil pump is also required. Then electric welding or screwing is installed and packaged for delivery.
Hardware processing belongs to the category of "furniture, engineering metal material accessories and frames" in the tax classification code. It is to process the raw materials (stainless steel plate, copper material, aluminum material, iron material.) into various parts according to the customer's engineering drawings or samples with CNC lathes, CNC lathes, planers, grinding and polishing. , Such as: screws, motor shafts, model car parts, fishing tackle accessories, audio commodity casings, mobile charger casings, etc.
The subdivision of hardware surface processing can be divided into: metal spraying processing, electroplating, surface grinding and polishing, metal etching processing and so on. Spraying processing: Hardware factories use spraying processing when producing large-scale hardware products, and use spraying processing to prevent hardware from rusting, such as daily necessities, home appliance casings, artworks, etc.
