The stamping process is a metal processing method, which is based on the plastic deformation of metal. It uses molds and stamping equipment to apply pressure to the sheet to cause plastic deformation or separation of the sheet to obtain a certain shape, size and performance. Parts (stamped parts). Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of parts, which is easy to realize mechanization and automation, and has higher production efficiency. At the same time, stamping production can not only strive to achieve less waste and no waste production, but also has margins in some cases. The leftover material can also be fully utilized.

The spade tooth process is used to make heat sinks and is mostly used for heat dissipation of high-power parts. Because it has a one-time molding, does not lose the heat dissipation performance of the profile, it reaches 100% of the original heat dissipation performance of the profile, and it also has the characteristics of large size and high power. High-power motors are widely used. It is mostly used in large radiators such as photovoltaic inverters, wind power converters, electric vehicle controllers, and power battery packs. The shovel process can also be used with other heat dissipation processes, such as the heat pipe process mentioned above, and can also be combined with water-cooling plate technology, micro-channel technology, etc., according to the characteristics of different motors to make radiators of different shapes and sizes, with different combinations The technology can improve the performance of the radiator while reducing costs. The shovel teeth do not require high profile materials, and they can be aluminum or copper profiles.

The heat pipe is generally a hollow cylindrical pipe, a part of which is filled with liquid that is easy to evaporate. The vacuum state is always maintained in the tube, and the evaporation temperature of the liquid in it is close to the ambient temperature. When the heat is absorbed by the volatile layer, the liquid is quickly heated to the boiling point, and then begins to boil, producing steam, and the steam rises to the cooling layer. When the heat is released, the steam recondenses into droplets due to gravity or other The internal effect of the droplets is to return to the volatile layer, continue to be evaporated, and then be cooled, which forms a cyclical cycle, which promotes this cycle is the heat source, which is the principle of the heat pipe process. Heat pipes have extremely high thermal conductivity and good isothermal properties. The heat transfer area on both sides of the cold and heat can be changed arbitrarily, heat can be transferred over a long distance, and temperature can be controlled. In the early days of its birth, it was mainly used in aerospace, military and other industries. Industries such as metallurgy, chemical industry, transportation, machinery and electronic technology have been widely used. Now, heat pipes have become the mainstream configuration components for high-end PC heat dissipation on the market. Compared with traditional metal radiators, heat pipe radiators have the technical advantages of low noise and high performance. As the technology continues to mature and large-scale production applications, heat The price of catheters is becoming more and more acceptable.

Both the FIN process and the reflow soldering process are technologies designed for the heat conduction of heat pipes and radiating fins. The FIN process, as the name implies, is to insert the heat conduction heat pipe into the heat dissipation fins, without any heat conduction medium between them, and only rely on direct contact to conduct heat. The heat dissipation fins through the FIN process are not a simple plane, but are in contact with the heat pipe. In this way, the heat dissipation fins of the FIN process are stacked layer by layer, and the heat pipe can be completely wrapped, and the heat dissipation effect will not be much worse than that of the heat sink of the reflow soldering process.

High-frequency welding refers to a welding method that uses high-frequency current to flow through the resistance heat generated by the contact surface of the workpiece, and applies pressure (or no pressure) to connect the metal of the workpiece. Generally, the frequency of high-frequency welding is selected in the range of 300 to 450 kHz. High-frequency welding can be divided into contact high-frequency welding and induction high-frequency welding according to the way that high-frequency current generates heat in the workpiece. When contacting high-frequency welding, high-frequency current flows into the workpiece through mechanical contact with the workpiece. During induction high-frequency welding, the high-frequency current generates an induced current in the workpiece through the coupling action of the outer induction coil of the workpiece. High-frequency welding is a highly specialized welding method, which must be equipped with special equipment according to the product. The productivity is high, and the welding speed can reach 30m/min. Mainly used for welding longitudinal seams or spiral seams when manufacturing pipes.

According to the forging temperature, it can be divided into hot forging, warm forging and cold forging.
According to the forming mechanism, forging can be divided into free forging, die forging, ring rolling, and special forging.

Forgings used in most industries are hot forging. Warm forging and cold forging are mainly used for forging parts of automobiles and general machinery. Warm forging and cold forging can effectively save materials.

Forging materials are mainly carbon steel and alloy steel with various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original state of the material includes bar stock, ingot, metal powder and liquid metal.
