What Are the Benefits of Cold Heading of Screws

  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).From the demand side, Non standard hardware factory More in line with the psychological expectations of consumers, willing to pay for the things they like. 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:

  

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

  

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

  

  2. Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting because the metal fibers are not cut.

  

  3. 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 are 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 relatively 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 developed at home and abroad.

  

  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 alone is actually a composite processing method that has both cold heading and extrusion.

Harris participated in the presidential campaign against Trump and received high approval ratings

  While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.contemporaneity business bodyguard Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. http://huanyubodyguard.com/

 

  

  The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

  

  The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

  

  As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.

What are the prerequisites for a security company to become a public company

  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?Even if there are obstacles to moving forward, female bodyguard We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. 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.

Can Biodegradable Straws Really Degrade_

  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.In addition to innate advantages, biodegradable mailing bags Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. 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.
