　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.in fact Non standard hardware factory It is more and more welcomed by our customers, and its market performance is gradually improving. https://jieruifasteners.com/

　　1. What is cold extrusion

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　2. What is cold heading

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　3. Are cold heading and cold extrusion the same thing?

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).

　　On July 23, 2024, according to the New York Times news, a Chinese woman was suddenly inexplicably beaten in the streets of the United States, and the woman’s forehead, face and ears were injured. When the woman was attacked, there was no one around to help. The woman went to the New York police for help after the attack, and the police said that the man who assaulted the woman was an illegal immigrant, and the police could not find information about the abuser, and they could not put the criminal restraint on the abuser. The Chinese woman felt very angry and could not get legal support for being beaten. Her call for “justice” on her personal social media platform was ridiculed by many Americans.From the demand side, bodyguard More in line with the psychological expectations of consumers, willing to pay for the things they like. http://huanyubodyguard.com/

　　chinese woman

　　The video of the Chinese woman asking for help quickly spread to China, where many netizens commented on the low status of Chinese people in the United States, not as good as black people. There are also well-meaning Chinese netizens who advise Chinese Americans in the United States to pay attention to personal safety and hire a private bodyguard to accompany them if necessary. Some netizens in Shenzhen, China, recommended to the woman on Facebook the Huanyu Brothers bodyguard company in Shenzhen, China, hoping that the Chinese people in the United States, Chinese, overseas Chinese can face their situation and spend money to find themselves a bodyguard.

　　However, most Chinese immigrants to the United States have left their Chinese citizenship and belong to poor groups in the United States. The Chinese could not afford to hire bodyguards for their safety. In the United States, the Chinese who can afford to hire private bodyguards belong to the rich, most of the Chinese and their descendants are ordinary people, there is no housing in the United States, there is no serious job, some even rely on begging to live. Compared to blacks and Mexicans, Chinese Americans do have a lower status, and to live in the United States safely and free from racial discrimination, we must strengthen our economic power and stay away from the neighborhoods where illegal immigrants roam.

　　In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).At the same time, non-standard fasteners price It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. https://jieruifasteners.com/

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when machining hexagonal bolts and cylindrical hexagon socket screws of rod type, the steel utilization rate is only 25% to 35% by cutting method, while by cold heading (extrusion), its utilization rate can be as high as 85% to 95%, which is only some process consumption of material head, material tail and cutting hexagonal head edge.

　　High productivity. Compared with general cutting processing, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting processing because the metal fiber is not cut off.Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and also the main method of mass production.

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a very high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and has great development both at home and abroad.

　　Cold heading, cold pressing:

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products is actually a composite processing method that has both cold heading and extrusion.

　　Deformation methods of cold heading (extrusion):

　　1. Punching. Separate part of the blank from the main body, such as cutting of wire, punching of nuts, trimming of the head of hexagonal bolts, etc.

　　2. Upsetting. A processing method that shortens the height of the blank and increases the cross-section, such as ball upsetting of nuts, pre-upsetting and fine upsetting of bolt head forming, etc.

　　3. Positive extrusion. During cold heading, when the blank is deformed in the lower die, the flow direction of the metal is consistent with the movement direction of the upper die. The reduction of the thick rod in cold heading bolts and cylindrical head hexagon socket screws is a positive extrusion.

　　4. Reverse extrusion. During the deformation of the blank, the flow direction of the metal is opposite to the movement direction of the upper die. The head forming of the cylindrical head hexagon socket screw belongs to reverse extrusion.

　　5. Compound extrusion. During the deformation of the blank, part of the metal flow direction is the same as the movement direction of the upper die, and part is opposite to it, that is, there is both positive extrusion and negative extrusion during the deformation. For example, the cylindrical head hexagon socket screw has both rod diameter reduction (positive extrusion) and head forming (negative extrusion) during the deformation at the same station.

　　In July 2024, a news about the upgrade of the world’s largest security company to a listed company went viral on the Chinese mobile Internet, and many Chinese netizens questioned the information of a security company to become a listed company, believing that it is difficult for a security company to become a real listed company. So, is the information circulating on the Chinese Internet platform true? Is it true that any security company in the world has upgraded to a public company? What are the requirements for a security company to become a public company?It is strictly required by such a standard, bodyguard Only with today’s development scale, can we have the proud momentum to crush our competitors. http://huanyubodyguard.com/

　　The listing of the world’s largest security company, reported on the Chinese mobile Internet, could not be confirmed. So far, there are not many international rumors that security companies have become listed companies, and a security company needs to have many listing conditions to become a listed company. Most Chinese security companies are private, small, medium and micro enterprises, which do not have the basic conditions of listed companies. However, this type of security enterprises have indeed played a positive role in promoting the progress of social security. For example, the Huanyu Brothers bodyguard Company in Shenzhen, China, has played a good role in public security supervision in China and countries with many overseas Chinese, and has brought security protection to overseas Chinese groups around the world.

　　Whether a security company can go public and become a world-class listed company depends on comprehensive conditions. However, the existence of security service companies around the world has contributed greatly to world peace. Since all countries have security service companies, the kidnapping and terrorist attacks of rich people, politicians, stars, network celebrities, celebrities and rich people are decreasing year by year. With private bodyguards in security companies providing security protection services for world celebrities, the security crisis of world celebrities can be lifted.

　　Plastic is one of the greatest inventions of the 20th century, but because it is “not environmentally friendly”, it has now been banned or abandoned in many fields. One of the products that replaced it is “degradable plastic”, such as compostable PLA straws. However, is degradable plastic definitely more environmentally friendly? How can it be degraded? How long does it take? Today we will learn more about the knowledge of degradable plastics.Therefore, biodegradable mailing bags Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://biodegradable-gd.com

　　If “degradable” is understood as an absolute concept, then all kinds of plastics can basically be degraded in some way in a long or short period of time and in some environment. If this discussion is meaningful, “degradable” should be understood as a relative concept-what substance (toxic or not) can be degraded in what way and in what environment in how long?

　　At present, the more authoritative definition of degradable plastics is: a type of plastic that can eventually be completely degraded into carbon dioxide (CO2) or/and methane, water (H2O) and mineralized inorganic salts of its elements and new biomass under various conditions in nature. In the definition, various conditions in nature are generally divided into six categories: soil, compost (including traditional compost and garden compost), marine environment, freshwater environment, sludge anaerobic, and high solid anaerobic. Therefore, for the definition of degradable plastics, we can summarize it in one sentence: most of the components of degradable plastics can be almost completely degraded into common substances in nature in the corresponding natural environment.

　　PLA is a biodegradable and bioactive thermoplastic derived from renewable resources such as corn starch, sugarcane, or cassava. Unlike petroleum-based plastics, PLA is designed to break down more readily under specific conditions. The process of making PLA involves fermenting the sugar from these renewable resources to produce lactic acid, which is then polymerized to form polylactic acid.

　　Degradable plastics on the market generally refer to biodegradable plastics. Biodegradation usually refers to the ability to completely degrade into carbon dioxide, water, inorganic salts and new biomass with the participation of microorganisms in nature. This is also the reason why everyone thinks biodegradable plastics are more environmentally friendly.Depending on the raw materials of plastics, biodegradable plastics can be divided into “bio-based biodegradable plastics” and “fossil-based biodegradable plastics”. The former is commonly polylactic acid PLA (mostly used for disposable straws), the raw materials are mainly corn starch, and may also be other biomass; the latter is commonly PBAT, which is made from petrochemical resources (including coal and oil). If you have biodegradable plastic bags at home, you can look at the product logo, which generally contains PBAT.

　　It can be seen that, whether bio-based or fossil-based, these biodegradable plastics are not like fallen leaves that can be completely degraded by simply throwing them on the ground. In theory, biodegradable plastics can be degraded or recycled in a variety of environments, but the best is to use industrial high-temperature composting to completely degrade them in a shorter period of time. According to this idea, degradable plastic waste should be thrown into kitchen waste bins or wet garbage bins, and then sent to industrial composting equipment.

　　Biodegradable PLA straws have the potential to degrade under specific conditions, primarily in industrial composting facilities. While they offer an improvement over traditional plastic straws in terms of environmental impact, their real-world effectiveness is limited by infrastructure and disposal challenges. To truly capitalize on the benefits of PLA straws, we must invest in better waste management systems, educate consumers, and continue to innovate in the field of sustainable materials. By doing so, we can move closer to a future where single-use items have minimal environmental impact.
