Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene. Progressive dies are commonly feed from a coil of steel, coil reel for unwinding of coil to a straightener to level the coil and then into a feeder which advances the material into the press and die at a predetermined feed length.
Stamping is usually done on cold metal sheet. See Forging for hot metal forming operations.

Most power grid purchasers have become search engine workers.
When most online shopping companies around the world are still immersed in the so-called low-cost operation of the Internet era, a new discussion about the core competitiveness of online shopping companies has begun. At this time, the global online shopping giant Amazon seems to be worthy of recollection. When China's power grid purchasers are busy expanding and adjusting the layout of online stores, Amazon has announced the layout of physical networks, and plans to open physical retail stores in Seattle in the next few months. In fact, the mode of simply satisfying the move of products from offline stores to online sales is not true e-commerce. The essence of home grid purchase is to quickly meet and create user demand by continuously improving the control capabilities of the entire industry chain. At present, most power grid purchases exist only as a window for consumers to present shopping on the Internet, and have not yet explored a truly differentiated business model. In this sense, most of the current power grid purchase companies can only say that they have opened an electronic product online store. Because of the imperfect aspects in logistics and warehousing, most of the power grid purchase companies are working as search engines. The role of the person exists and lacks a relatively mature development strategy. For the home appliance industry, online shopping is an important channel for the development of the electronics industry in the future. Online shopping can completely record the consumer's shopping process, demand and after-sales feedback on the network. Through these digital consumption trajectories, online sellers It can analyze the accurate needs of consumers and feed back to relevant manufacturing companies to optimize products. This is the basic meaning of the existence of power grid purchase channels. To be precise, e-commerce should be called accurate business. Since its inception, its ultimate goal is to achieve a seamless connection between consumer demand and product manufacturing systems. This is the biggest problem facing e-commerce or all retail companies. . In the case of highly developed Internet, the home grid purchase market will have such a situation: consumers put forward specific requirements for products on the network, and the home grid operators timely sorted out these requirements and fed back to manufacturing companies, manufacturing companies and The home grid company jointly develops and manufactures products and delivers them to the customer side. This is a complete industrial cycle to meet consumer demand. As far as the current industrial situation is concerned, most home power grid purchase companies are far from mature, only exist as a price-killing platform, and its cost structure control is rather weak: on the one hand, because the current home network purchase channel traffic is relatively small, Sogou can not The manufacturer has obtained a policy superior to the physical network, and the comprehensive procurement cost lacks a comparative advantage. On the other hand, due to the imperfect layout in terms of warehousing and logistics, the cost control of the home grid purchaser in this area is weaker. What's more, under the current industrial structure, online shopping companies can't leave the high-frequency promotion. The repeated high-frequency promotion on the Internet makes the marketing cost of online shopping companies so high, so even if the traffic is relatively enlarged, the focus of the real estate network, but The overall situation is still at a loss, and a considerable portion of the profits are taken away by search engines. The mature home grid purchase ecology should be like this: It can truly customize different products that meet the different needs according to the needs of different consumers, and has strong control over the whole industry chain such as warehousing, logistics, after-sales and product customization. It can achieve steady development by accurately and quickly meeting user needs. From this point of view, most domestic power grid purchase enterprises are still in the primary stage of the industry, and the future development path is still very long.
