　　1. Understanding Non-Standard Fasteners

　　Non-standard fasteners are custom-made or specially designed fasteners that deviate from the typical industry specifications. These fasteners are crafted to meet unique design and performance requirements that standard fasteners cannot fulfill. Non-standard fasteners can come in a variety of shapes, sizes, materials, and designs that are tailored to specific applications. The ability to customize these fasteners allows manufacturers to solve complex design challenges, improve the functionality of their products, and ensure higher levels of durability.

　　2. The Role of Customized Fasteners in Product Quality

　　Customized fasteners are often essential when dealing with specific materials, tight tolerances, or challenging environments. Here are some ways in which they contribute to improved product quality:

　　Tailored Fit for Precise Applications

　　Customized fasteners are designed to fit exact specifications, providing a more secure, accurate, and long-lasting connection. When the right fastener is used, it ensures that all parts of a product are held together correctly, minimizing the risk of failure due to loose or misaligned components.

　　Enhanced Durability and Performance

　　Custom-designed fasteners are made from materials chosen to withstand particular environmental conditions such as high temperature, moisture, corrosion, or vibrations. The selection of high-quality materials ensures that the fasteners endure the wear and tear of demanding applications, which directly improves the durability and performance of the end product.

　　Improved Safety and Reliability

　　A critical factor in product quality is safety. Non-standard fasteners are engineered to meet specific safety standards, ensuring the integrity of critical components. Whether it¨s for aerospace, automotive, or medical devices, using non-standard fasteners helps maintain the structural integrity of the product, reducing the risk of product failure and increasing its reliability.

　　Reduced Maintenance Costs

　　Customized fasteners that are designed for a specific purpose often require less maintenance over time. By ensuring a perfect fit and optimal performance, manufacturers can reduce wear and tear, leading to lower maintenance costs and longer product lifecycles. This ultimately results in a better overall product quality and reduced long-term costs.

For this reason, it can be speculated that 搜狗输入法 The market feedback will get better and better, which is one of the important reasons why it can develop. https://shurufa.sogou.com

According to a report by the Russian News Agency on July 15, Vladimir Talabrin, Russia’s Permanent Representative to the Organization for the Prohibition of Chemical Weapons and Russian Ambassador to the Netherlands, told reporters on the 15th that Western countries intend to accuse Moscow of using chemical weapons.

Talabrin reportedly said: Yes, they are working hard to do the work of the Technical Secretariat of the Organization for the Prohibition of Chemical Weapons to force it to take some steps intended to accuse Russia of using chemical weapons.

He said that Russia is fighting back against this in every possible way, trying to prove with concrete facts that all these efforts are futile.

Talabrin said that Russia does not and cannot pose a chemical weapons threat to Ukraine. He pointed out that Moscow does not rule out inviting experts from the Organization for the Prohibition of Chemical Weapons to study evidence of Kiev’s use of such weapons.

The 106th session of the Executive Council of the Organization for the Prohibition of Chemical Weapons was held in The Hague from July 9 to 12. Talabrin said after the meeting that Ukraine blatantly violated the convention and used military poisons against Russian troops, a point that many foreign experts and agencies have talked about. They noted that Ukraine’s armed forces were actively using drones to transport toxic chemicals. In addition, the United States, which supplied these substances to Kiev, is also violating the convention.

Lieutenant General Igor Kirilov, commander of the Radiation, Chemical and Biological Protection Forces of the Russian Armed Forces, said at a press conference that Kiev frequently violated the Chemical Weapons Convention. At the same time, the Organization for the Prohibition of Chemical Weapons, which was supposed to oversee the implementation of the convention, is now completely controlled by the West, which uses the organization to settle political scores with Russia.

Houston, May 15 (Reporter Xu Jianmei) The municipal authority of Galveston, an island city in eastern Texas, said on the 15th that a barge hit a local bridge that day, causing a fuel leak and damage to the bridge.

The bridge involved was the only land route to Pelican Island north of Galveston. David Flores, head of bridge affairs for the Galveston County Navigation District, said that due to strong water and high waves, a tugboat from Texas International Port lost control of two refueling barges it was driving, one of which hit the bridge pillar.

Aerial footage showed that part of the bridge pillars collapsed, and large pieces of broken concrete and rail fragments hung on one side of the bridge and fell onto the barge.

After the accident, the bridge, which was opened in 1960, was closed. Galveston City Authority said in a statement that no injuries had been reported. The accident caused a fuel leak in the Gulf of Mexico, and the U.S. Coast Guard will determine the extent of the leak and initiate control and cleanup procedures.

Galveston County spokesman Spencer Lewis said the barge could carry 30,000 gallons of oil (about 113.55 million liters). It was unclear how much leaked into the bay. About 105 kilometers of waterways around the incident were closed.

Texas A & M University at Galveston on Pelican Island said the accident caused a brief power outage at the school and power has now been restored.

According to US media reports, American ship collisions with bridges have occurred frequently in the past few months. On March 26, a container cargo ship crashed into a bridge in Baltimore, Maryland, in the eastern United States and collapsed, killing six people. On April 12 and 13 on the Ohio River near Pittsburgh, Pennsylvania, 26 inland river barges separated from their moorings due to floods and drifted uncontrollably, when one hit a bridge that had been closed. On May 9, a large barge broke loose from a tugboat on the Mississippi River flowing through Iowa and sank after hitting the nearly century-old Fort Madison Bridge.

　　According to the latest data of China Automotive Power Battery Industry Innovation Alliance, from January to December, 2023, a total of 52 power battery enterprises in China’s new energy vehicle market achieved vehicle loading facilities, 5 fewer than the same period of last year, and the elimination rate was close to 10%.By comparison, it can be seen that Adjustable Film Applicator:10 It has certain advantages and great cost performance. https://www.canrud.com/products/detail/36df5c66ebdf46a69067a9bd5c7ad81f

　　On the other hand, the top ten power battery enterprises have loaded 375.3GWh, accounting for 96.8% of the total vehicle. Compared with 95% in 2022, 93.5% in 2021 and 91.8% in 2020, power battery companies have staged the drama that the stronger the stronger.

　　Power battery companies ranked lower are struggling.

　　Gateway Power, a lithium battery factory owned by Galaxy, is obviously one of them. From January to October, 2023, the loading capacity of Gateway Power was only 0.88GWh, ranking 13th. Now, the company has stopped production for two months.

　　Source/Weibo New Energy Prospective Screenshot

　　Jiewei Power was established in 2009 with a registered capital of 1.218 billion yuan. It is a 15-year veteran lithium battery enterprise. Once, it was full of lofty sentiments. It became the top 3 in the power battery industry in five years, ranked among the top 3 in the world in 10 years, applied for IPO of A shares in 2022, and strived for listing in 2023. After all, it was “but before he could conquer, he was dead”.

　　Obviously, in the power battery industry, there are still many battery manufacturers that are not as good as Jiewei Power. They are also facing many problems, even life and death tests. How do you spend this winter?

　　01

　　Small battery factories are getting worse every year.

　　The person in charge of the lithium battery manufacturer who suffered in 2023 will definitely miss 2022, especially the “small factory” of lithium batteries.

　　Wu Sujun, a grassroots employee who has worked in Jiewei Power for more than ten years, once told the media that the company still has some orders in 2022, but the quantity is not large. Mainly small modules, not finished products. In 2023, there was no order, and the factory could only do some battery repair work, and about 200 sets were repaired every month.

　　Compared with more than 2,400 employees in the glorious period, gateway power had only about 400 employees left in its headquarters before the production stopped, and 200 people left after the production stopped. The 2022 annual report shows that in 2022, the number of social security participants of Jiewei Power was 882, which dropped by more than 70% in less than one year.

　　The closed production lines record the cruelty of the lithium battery industry. According to the Shenzhen Communique of the 10th G20！-Lithium Battery Summit, since 2023, the average capacity utilization rate of domestic power batteries is less than 60%, and that of energy storage batteries is less than 55%.

　　Figure/Jiewei Power Electric Center Workshop

　　Source/Gateway Power Official Website New Energy Prospective Screenshot

　　In fact, in addition to the power battery companies such as Jiewei Power, there are also four major materials (cathode materials, anode materials, separators and electrolytes) for lithium batteries.

　　In terms of capacity utilization rate, many companies disclosed that the overall capacity utilization rate of the anode industry decreased significantly in 2023. Even the leading enterprise Shangtai Technology announced the suspension of production in the first quarter of 2023.

　　On the evening of March 27, 2023, Shangtai Technology announced that Licheng Road Base had stopped production. It is reported that Licheng Road Base started construction in 2008. It is the earliest production base of Shangtai Technology, and also the starting place and birthplace of the company’s entrepreneurship, with an annual production capacity of over 10,000 tons.

　　”The supply and demand of the entire anode material industry has reversed, facing a situation of overcapacity.” Shangtai Technology clearly stated in the announcement.

　　The performance of Ferrous lithium phosphate cathode manufacturers in operating rate is also relatively sluggish. According to market data, in November 2023, the average operating rate of manufacturers was less than 50%, and it has accelerated to about 20% since December. The output of cathode materials in Ferrous lithium phosphate has reached a new low since June 2023.

　　02

　　Solve overcapacity

　　”Surplus” became the label of lithium battery industry in 2023.

　　Mr. Gang ‘an, the technology developer of Jiewei Power, said that the company kept investing in building factories, which eventually led to overcapacity.

　　How many lithium batteries did Gateway Power produce? According to the information of official website, Jiewei Power has two production bases, Yancheng and Changxing, with an effective production capacity of 10GWh. Jiewei Power CEO Lu Chenli announced in 2022 that the company plans to reach the power battery production capacity of 100GWh in 2025.

　　Source/Gateway Power Official Website New Energy Prospective Screenshot

　　Zhu Huarong, Chairman of Changan Automobile, once predicted that by 2025, the demand for power batteries in China will be 1000GWh, while the production capacity of the industry has reached 4800GWh, and the degree of excess can be imagined.

　　The four major materials of lithium battery also have different degrees of surplus. Some organizations predict that the global electrolyte capacity planning will exceed the demand by 3.4 million tons in 2025.

　　It is also a means of self-help for the lithium battery factory and the four major material enterprises behind it to delay the production capacity and adopt the low inventory procurement policy.

　　The semi-annual report of Contemporary Amperex Technology Co., Limited in 2023 shows that its inventory is only 48.91 billion yuan, which is 27.76 billion yuan less than that at the end of 2022. Zhongchuang Singapore Airlines, the third in the industry, cleared its inventory slightly, and its inventory decreased from 11.82 billion yuan at the end of 2022 to 10 billion yuan, a decrease of 18.2%.

　　Enterprises in the upper and middle reaches of lithium batteries have been kidnapped by the “game theory” of production capacity, forcing low inventory.

　　Jin Yiteng, an open source securities company, said that as the pace of production scheduling in downstream battery factories declined and the price of lithium battery materials in the middle reaches continued to fall due to overcapacity, battery factories also adopted a lower raw material inventory procurement strategy, forcing middle-stream lithium battery materials enterprises to reduce their start-up, maintain low inventory, and delay the launch of new capacity.

　　Low inventory is obtained on the premise of price reduction. According to the data of Xinyi Lithium Battery, an industry research institution, on January 24th, 2024, the average price of square Ferrous lithium phosphate power battery and energy storage battery was 0.38 yuan /Wh and 0.43 yuan /Wh, respectively, which was more than 50% lower than the price of 0.9 yuan /Wh in early 2023, and the price has reached the lowest point in history.

　　The seriousness of the price reduction can be seen. According to the statistics of Hi-Tech Lithium Battery, compared with 2022, the gross profit margin of diaphragm listed companies in the third quarter of 2023 decreased by about 40%, the electrolyte field decreased by about 25%, the cathode field decreased by about 20%, the ternary cathode decreased by about 9%, and the iron-lithium cathode decreased by about 5%.

　　Power Battery 2024: More Fierce Fight

　　”After experiencing rapid growth in demand and production capacity, the lithium battery field is currently facing the challenge of overcapacity. It is expected that supply and demand will further deteriorate in 2024 and it is expected to ease in 2025. ” Huatai Securities pointed out.

　　One of the most eye-catching gems at the Pueblo Gem Show in Colorado is a crystal known as the Rainbow Lattice. This rare gem is an feldspar gemstone with the placer gold effect, which is caused by exsoluted hematite crystals, and the rainbow lattice effect, which is caused by oriented exsoluted magnetite crystals. The gemstone is very limited in origin and is currently only produced in a small mine in Australia¨s Northern Territory known as the Buck Hills. The Rainbow plaid gemstone was first discovered in 1985 and recognized as a new gemstone in 1989.

모모Rough Polishingknow jewelry manufacturer Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://tonglinring.com/

모모

모모1, First of all, the rough toss. Rough polishing is to throw away the file marks, pliers marks, drill marks, burrs and the black oxide layer left by welding on the surface of the jewelry metal bracket, and try to throw the jewelry metal bracket flat and coordinated, so that the arc is smooth and the lines are smooth. But also can not be too hard, polishing too hard, such as in the jewelry bracket surface left a depression will be difficult to restore its appearance. Rough casting is the basis of medium casting and fine casting. If it fails to meet the requirements, it will affect the later polishing and directly affect the quality of jewelry.

모모

모모Polishing Brush

모모

모모2. Then start polishing motor, rotate polishing brush (Zong brush) by motor shaft rotation force, brush tightening will be coarse sweeping agent C green wax block (containing chromium oxide) daub on the brush, you can polish.

모모

모모3. The brush is mainly used to polish the mesa of the inlaid jewelry, the main and auxiliary stone edging, the gap of the decorative decoration and the outside of the ring, but also to polish the reverse side of the jewelry. In the process of operation, the first thing to pay attention to is to evenly polish the wax to the brush, polishing force should be appropriate, not too much force and cause jewelry deformation, claw, loose claw, and even stone phenomenon, also can not polish is not in place and still have residual file marks, scratches, etc. All jewelry should be rough polished again, polishing is not obvious enough to repeat polishing.

모모

모모4. If polishing the inlaid ring, the inner ring of the ring should be polished with a velvet rod, and the appropriate velvet rod should be selected according to the needs. Green polishing wax must be applied to the ring velvet core before polishing. When throwing, pay attention to the contact surface of the velvet mandrel and ring, that is, the ring can not be set into the velvet mandrel too deep, and keep the polishing contact surface is 1/3 of the inner circle arc. Polishing Angle surface is too small, the working efficiency is low; If the contact surface is too large, it is very inconvenient to change the polishing position. Moreover, due to the large friction resistance, it is difficult to hold the jewelry to be polished, and it is easy to cause the polished jewelry to fly out and damage the shape of the gem ring surface or jewelry.

모모

모모5, rough polishing should pay attention to the brush and cloth wheel waxing, but a waxing can not be daub too much, to avoid polishing wax after the heat to melt it covered on the surface of the jewelry, and cover the jewelry surface traces and pockmarks, which will affect the quality of rough polishing jewelry, and bring difficulties to fine polishing, and even lead to rough polishing again.

모모

모모6, Polishing operator polishing techniques will also affect the quality of polishing, polishing operation is not correct, it is impossible to throw good jewelry. Generally speaking, when polishing, try to make the jewelry parallel to the polishing cloth wheel, hold the jewelry tightly with both hands and move along the cloth wheel from the top down. Polishing must be done evenly all parts of the jewelry at once, each part must be thrown in place. The polishing technique is not correct, and the polished jewelry is easy to be flicked off the hand on the high-speed polishing wheel, which is very easy to cause damage to the gem ring surface, deformation and fracture of the metal bracket. If the polished jewelry is small in size (such as chest pendants and ear studs), you can prepare a hook made of wire. Keep the polished jewelry with your left hand, and avoid skipping polishing and uneven weight of force during polishing. If there is a jumping phenomenon, it may be that the polishing wheel is not on the axis, it may also be that the polishing cloth wheel is not round, it is more likely to be the gesture problem, find out the reason, it is good to solve the problem.

모모

모모7, Some of the more difficult polishing of alloy jewelry, due to the metal toughness of jewelry in the soft metal cast light retention phenomenon, not easy to throw bright metal surface, can only be repeatedly polished to meet the requirements, such as platinum jewelry as far as possible polishing, polishing method and rough polishing is basically the same, still with a brush and yellow cloth wheel polishing, polishing wax is different, It mainly uses white polishing wax with fine particle size (it is an oxide containing aluminum). Medium polishing is to operate in accordance with the rough polishing method, the jewelry from beginning to end again.

모모

모모Fine Polishing

모모

모모8, Any jewelry after rough polishing must be fine, so as to make the metal jewelry surface finish stronger, fine polishing is further fine polishing on the basis of rough and medium polishing, make the jewelry surface more flat, smooth, to achieve the effect of mirror reflection. But its polishing friction contact surface is small, polishing not only the force should be small and uniform, and the surface of the jewelry must be completely polished again, the specific method is to use a fine white cloth wheel with red polishing wax, polishing the front of the jewelry, and then polishing the side of the jewelry, the corner. If the ring is polished, it should be polished with red wax on the ring velvet core rod. Then, polish the front of the ring on the floral shoulder, and finally polish the sides and outer ring of the jewelry.

모모

모모9, The jewelry after rough polishing, polishing and fine polishing 3 times, it should be said that the surface of the jewelry can reach the degree of smooth as a mirror. But sometimes because the grinding is too rough, there are still large file marks and scratches on the surface of the jewelry. It몶s very difficult to remove it through the polishing procedure. There is also the polishing process will row cover in the jewelry surface under the pitting spot grinding out, which not only affects the finish of the jewelry but also affects the quality of the jewelry, the situation must be trimmed, the jewelry on the trace file mark to use the hanging grinder to sweep the needle sandpaper to polish. Jewelry surface pitting spot must be repaired welding, grinding flat before polishing.몪몪

On January 12th, the State Council held a press conference on the import and export situation in 2023. China’s electric vehicles, lithium batteries and solar cell products became the “new three products” with a large increase in export volume, which not only reflected the effect of industrial upgrading, but also continued to promote domestic industrial integration and enterprise upgrading behind the scenes.To get brand praise, lithium ion battery electrolyte:590 It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.canrud.com/products?keyword=electrolyte

　　The development of things often has two sides. In the “new three kinds” lithium battery industry, China has an absolute advantage, but it has been blocked more and more in the process of going to sea. Competition is intensifying and overseas restrictions are increasing. To what extent can the export of lithium batteries relieve the pressure of overcapacity for enterprises? For the enterprise itself, what other methods can be the core of breaking the game?

　　In 2024, the lithium battery industry was busy looking for answers.

　　01

　　”The Wave of Lithium Battery Export”

　　In 2023, the annual press conference on import and export released the key export data. The total export of electric vehicles, lithium batteries and solar cells in China was 1.06 trillion yuan, which was the first to exceed one trillion yuan, up by 29.9% year-on-year, making it a “new three” export.

　　Among them, lithium batteries have attracted a lot of attention because of the relatively new industrial structure, China’s leading technology and industrial strength, and strong export power.

　　According to the share and leading degree of China enterprises in the lithium battery market, the data released by SNE research, a well-known research institution in the industry, shows that in the first three quarters of 2023, the amount of batteries carried by various electric vehicles (EV, PHEV and HEV) in the world was about 485.9GWh, a year-on-year increase of 44.4%. Among them, China enterprises not only have an amazing market share, but also shake the market structure in terms of growth capacity.

　　In the first 11 months of 2023, six of the top ten companies in the power battery market share were China enterprises, with a market share of 62.9%; Contemporary Amperex Technology Co., Limited ranks first with a market share of 37.4%, and it is the only supplier in the industry with a market share of more than 30%. The year-on-year growth rate of installed capacity is also at a high level of 52%. BYD ranked second, and the installed capacity of batteries in the first three quarters increased by 71.4% year-on-year.

　　The leading position of Chinese enterprises in the new energy vehicle market is also clearly evidenced. In the early days, Contemporary Amperex Technology Co., Limited has been an important battery supplier of Tesla, and last year, it announced the cooperation with Ford to build a factory in the United States. In May last year, Tesla’s super factory in Berlin, Germany produced the first batch of BYD battery version Model Y. BYD blade battery was not only recognized by rivals, but also engraved its own name in the European market, which was self-evident.

　　With the strength behind this recognition, China Power Battery set a new record in the sea. According to the statistics of China Chemical and Physical Power Industry Association, in the first 11 months of 2023, the export of lithium batteries in China reached US$ 59.7 billion, or about RMB 424 billion, up 32.7% year-on-year. Among them, Europe accounts for about 40%, which is the largest export market, followed by the United States and Southeast Asia.

　　The advantages of China battery enterprises come from many aspects. The core reason is that China’s research and development of power batteries is in a leading position in the world, with rapid technological progress and good boarding effect, which is widely welcomed by car enterprises. For example, foreign media have tested Tesla’s charging data after carrying a blade battery. The results show that its high-power charging time lasts longer and its charging power is higher. BYD’s CTB battery structure can also work together with Tesla’s integrated die casting technology to reduce energy consumption.

　　On the other hand, the domestic battery industry developed earlier, there were a large number of market participants, and the tide of early financing expansion was fierce. Although it led to the problem of overcapacity, it drove the price of the whole industry down, making low costs more conducive to exports, and even forming a pattern of “leading technology and second-line capacity”. As early as 2022, players of different sizes in Contemporary Amperex Technology Co., Limited, Honeycomb Energy and other industries began to expand production by leaps and bounds, far exceeding the level that the market can digest in the short term.

　　The reduction of industrial chain cost has further added a fire to the madness of these players: A-share lithium battery materials companies generally experienced a decline in net profit in the semi-annual report in 2023. For example, Defang Nano, a leading cathode material company in Ferrous lithium phosphate, lost nearly 1 billion yuan in the first three quarters. We should know that the losses of upstream enterprises actually mean the cost reduction of battery enterprises.

　　Then, can the above dividends always escort the overseas expansion of Chinese enterprises? I am afraid the answer is no. In 2022, the year-on-year growth rate of China’s lithium battery exports was as high as 86.7%. According to the existing data, the growth rate in 2023 may not reach half of this data. The growth of market demand may not keep up with the growth of domestic capacity output.

　　What is even more worrying is the attitude of the main market. “Big customer” Europe attaches great importance to the new energy industry and is using a series of carbon policies to protect local enterprises. The United States, which has great growth potential, has chosen to be conservative and exclusive, which has directly cut off the way for many Chinese enterprises to enter. Even the cooperation between Contemporary Amperex Technology Co., Limited and Ford was only achieved after the production capacity was greatly reduced.

　　If you want to go to sea, the sea is uneven. The involution of power battery is already worrying. How to deal with these new concerns?

　　Just as the advantages of the power battery industry are clear, the emergence of the sea problem also has clear internal logic. Among them, the domestic involution is only the impact on profits, and the overseas geographical pattern is the big problem that may make going to sea “this road is blocked.”
