What do you need to know in advance before customizing medals

  Why should even the medals and badges be customized? This is a problem that many people don’t understand. In fact, in our life, no matter in schools or enterprises, we will encounter all kinds of competitions, and each competition will inevitably have different awards. Apart from some realistic material rewards, medals, trophies or badges are also essential.According to related reports, custom medals for awards To a large extent, it leads the changes of market conditions. https://www.karonmetal.com

  

  Customized medals, trophies and badges represent a sense of ceremony given by the organizers and a sense of honor given by the contestants themselves. Then what should we pay attention to when customizing medals and badges as demanders?

  

  First, the medal badge style

  

  When customizing the design style of medals and badges, it is necessary to integrate the design style that the customization party wants based on the purpose of the product and the inheritance of corporate culture and the spirit of events. At the same time, it is necessary to customize different types of products according to different scenes, and determine the size, proportion, coordination, appropriateness and standard of medal badge products.

  

  II. Contents of medals and badges

  

  Generally, the customized surface content of the medal badge is the company (school or organization) abbreviation, logo, theme and other information, so it is forbidden that too much information leads to the accumulation of words on the surface of the medal badge. As simple as possible, accurately and completely express the purpose of making medal badges.

  

  Third, the medal badge technology

  

  Because the materials for making medals and badges are different, the manufacturing process is also diverse. For example, the production of metal medals can be made into colorful and exquisite medals through baking paint and enamel processing, which has a strong three-dimensional effect and various patterns are prominent. Soft enamel and resin are used as coloring materials, and the surface can be plated with gold, nickel and other metal colors, which are smooth and delicate, giving people a very noble feeling.

  

  Fourth, medal badge materials

  

  The materials for making customized medals and badges need to be determined according to the needs of the customization party. Compared with precious metals, gold, silver and ordinary metals, the precious materials of gold, silver and precious metals are more expensive. The customization party can decide whether the medals are high-grade or not and what materials to choose according to the requirements of different scenes.

  

  V. Details of medals and badges

  

  The details of customizing the medal badge mainly show whether the font selection is appropriate when customizing the medal badge, and what style of medal wooden support and medal ribbon are selected to match the medal badge; The thickness of medal badge, the width of hem and edge, the plane arch surface, etc., are considered according to different customization requirements.

How Does Silicone Braided Electrical Cable Improve Safety

  Whether you are working with industrial machinery, consumer electronics, or automotive systems, the cables you choose can make a significant difference in the safety and efficiency of your devices. One such cable that stands out for its exceptional safety features is the silicone braided electrical cable. But how exactly does silicone braided electrical cable improve safety? Let¨s explore.By comparison, it can be seen that fluoroplastic high temperature electrical wire It has certain advantages and great cost performance. https://www.dxhightemp-wire.com

  

  1. High Heat Resistance for Safer Operation

  

  One of the most significant benefits of using silicone braided electrical cable is its ability to withstand extreme temperatures. Unlike traditional PVC or rubber cables, silicone can endure high temperatures without losing its flexibility or integrity. Silicone braided power cables are designed to operate in temperatures ranging from -50<C to +200<C, making them ideal for environments where overheating is a concern. In applications such as automotive, industrial machinery, or even high-performance electronics, cables that can resist heat contribute significantly to safety by preventing overheating, short circuits, and potential fires.

  

  2. Durable and Long-Lasting Performance

  

  Safety is not just about heat resistance!it¨s also about durability. Silicone braided electrical cables are highly resistant to wear and tear, chemical exposure, and mechanical stress. The braided construction provides an extra layer of protection, making the cables more resistant to abrasions and cuts. This durability reduces the risk of wire damage that could lead to short circuits or electrical fires. Whether the cable is being used in a rugged industrial setting or as a power source for home appliances, the longevity of silicone braided cables ensures safer, more reliable performance over time.

  3. Enhanced Flexibility in Tight Spaces

  

  Silicone braided cables are known for their remarkable flexibility, even in challenging conditions. This flexibility is particularly important in tight or confined spaces where rigid wires may pose a safety risk. The flexible nature of silicone braided power cables allows them to bend and twist without breaking or causing damage to surrounding components. This means the cables can be routed through complex systems with less chance of pinching or over-stressing, minimizing the likelihood of accidental electrical hazards.

  

  4. Flame Retardant Properties

  

  Another key feature of silicone braided electrical cables is their inherent flame-retardant properties. Silicone does not catch fire easily and, when exposed to flame, it tends to self-extinguish. This feature is especially important in environments where high heat or open flames are present, such as in factories, automotive applications, and power plants. By choosing silicone braided electrical cable manufacturers who prioritize high-quality, flame-retardant materials, you can enhance the overall safety of your electrical systems and prevent devastating accidents.

  5. Excellent Insulation Against Electric Shock

  

  Electrical insulation is critical to preventing dangerous shocks and electrical accidents. Silicone braided power cables provide excellent insulation properties that protect users from electrical hazards. The silicone rubber used in these cables is an excellent insulator, meaning that it prevents electrical currents from escaping and causing accidental shocks. This high-quality insulation is especially valuable in high-voltage applications, where the risk of electric shock is much higher.

  

  6. Chemical and UV Resistance for Hazard-Free Usage

  

  Beyond physical wear and tear, cables are often exposed to chemicals and UV rays, especially in industrial environments or outdoor settings. Silicone braided electrical cables are highly resistant to oils, solvents, acids, and UV radiation. This makes them ideal for harsh environments where exposure to these elements could degrade the quality of the cable. By maintaining their strength and insulation properties, silicone cables reduce the risk of dangerous breakdowns or chemical reactions that could lead to electrical accidents.

South Korea does not plan to compromise on doctors _strike_ South Korean government is ready to fight to the end

So, I believe crystal energy bracelet In the future, it will be promising to create a miracle belonging to the industry. https://echocrystal.net/

The medical profession in South Korea has been playing a game with the government for more than half a month, the general election is just around the corner, and the doctors’ strike is escalating.

According to Yonhap news agency quoted by the Global Times, 430 professors from Seoul University School of Medicine attended the meeting on the 11th to issue an ultimatum: if the government does not come up with a sincere and reasonable solution to the situation of interns and residents’ collective resignation, all professors will submit their resignations on the 18th. South Korean media commented that the medical front line is likely to fall into greater chaos.

The South Korean government does not intend to compromise, and responded on the 12th, expressing serious concern about this. South Korean President Yoon Yue issued a directive on the 12th, calling for the rapid promotion of health care reform measures, including expanding the enrollment of medical schools, in accordance with the principles.

In addition, the South Korean government has sent license revocation notices to nearly 5000 doctors who refused to return to work, and decided to send 20 military medical officers and 138public health doctors to 20 hospitals from the same day to meet their urgent needs.

With the intensification of aging, the demand for medical resources in Korean society is increasing day by day. The South Korean government announced plans to expand the enrollment of medical students in early February: the enrollment of medical schools in colleges and universities increased from 3058 at this stage to 5058 in the 2025 academic year. According to South Korean health authorities, if the current enrollment scale remains unchanged, there will be a shortfall of 150000 South Korean doctors by 2035.

But the plan to expand enrollment has drawn strong opposition from doctors’ groups and medical students. They believe that the move will lead to excessive health care, strain the funding of the health care system, and lead to a decline in the quality of medical education. Moreover, South Korea lacks the mechanism to regulate the choice of departments for medical graduates, and blindly increases the number of medical students, which will lead to the accumulation of medical resources in big cities. Some medical staff are also worried that the plan to expand enrollment will lead to a reduction in the income of doctors.

Recently, medical professors at a number of South Korean universities are planning to resign collectively. On the 7th of this month, the Emergency response Committee of the Association of professors of Ulsan University Medical College agreed that the professor would submit his resignation on his own. The Association of Professors of Yonsei University School of Medicine set up an emergency response committee on the 12th, and the Association of professors of Cheng Junkuan University School of Medicine held a meeting on the same day. The School of Medicine of Katuli University will meet this week to discuss whether to take collective action.

In response to the possible collective resignation of medical professors, Oval Office officials insisted that since the president demanded rapid progress in accordance with principles, even professors were no exception for collective actions that left the front line of health care in violation of the Medical Law.

As of the 11th, the South Korean government has sent advance notice of administrative sanctions such as revocation of medical licenses to 5556 interns and residents who have left their posts.

Cao Guihong, head of South Korea’s Ministry of Health and Welfare, said at a meeting on the 12th that the decision of the professor’s collective resignation from the Medical College of Seoul University threatened the lives and health of patients, and that the government would do its utmost to maintain the emergency diagnosis and treatment response system and solve the problem of disorder in the medical scene. He called on professors to protect the lives of patients and work with the government to bring outgoing internships and residents back to the medical front line.

On the 12th, the faculty of Seoul University School of Medicine proposed a compromise. They held a press conference in the Korean National Assembly, saying that both the government and the Korean Physicians Association should abandon their inherent position and entrust overseas authorities and institutions recognized by all parties to analyze South Korea’s health and medical indexes. and according to the results of the analysis to decide whether to increase the number of medical school enrollment, at the same time to build a dialogue mechanism with the participation of the government, medical association, government and opposition, national representatives, professors, internships and residents. Formulate practical basic medical, community and public health policies in the coming year.

However, according to Yonhap news agency, an official from the South Korean President’s Office confirmed on the 12th that the plan to expand the enrollment of medical schools by 2000 students a year will not be adjusted. This figure is scientific, and the government’s determination to promote health care reform has not changed.

Less than a month before South Korea’s parliamentary election on April 10, South Korea’s ruling party has regained a lot of support for its policy of expanding enrollment in medical schools. The results of an opinion poll released by Gallup in South Korea on March 8 showed that the good rate of President Yoon Yue’s administration performance was 39%, and the bad rate was 54%. As for the reasons for praise, the answer to the expansion of medical school enrollment accounted for the largest proportion, accounting for 28%, followed by prompt decision, courage and perseverance (9%). According to an opinion poll released by the agency on February 23, Yin Yue’s good evaluation rate was 34%, and the poor evaluation rate was 58%.

For this protracted standoff, some Japanese media commented that the demand for reconciliation in South Korea is growing day by day. Doctors and the government should not be in the boxing ring. People’s patience is disappearing. We must find a way out of this quagmire through dialogue.

Do you know what different colors represent on the circuit board

  As the mother of electronic components, circuit board plays an important role in electronic applications. According to different design principles, circuit boards can be divided into single panel, multilayer board, soft board, hard board, soft-hard board and so on.More importantly, put pcb assembly manufacturer It is imperative for us to make thorough analysis and maximize its social function. https://intechcircuit.com/

  

  At present, the common PCB colors on the market are green, black, blue, yellow, purple, red and brown, and white and pink PCBs have appeared recently.

  

  So, why do PCB boards have different colors? Have you found that most of the circuit boards are green, but other colors are rare? Why? Next, Shenzhen Lianxiaobian will give you a wave of knowledge about circuit boards ~

  

  Why do PCBs have different colors?

  

  In the production process of PCB, the final surface of copper layer is smooth and unprotected, whether by additive process or reduction method. Although the chemical properties of copper are not as easy to oxidize as pure copper of aluminum, iron and magnesium in contact with oxygen in water, the thickness of copper layer in PCB circuit board is very thin, and the oxidized copper will become a poor conductor of electricity, which will greatly damage the electrical performance of the whole PCB. In order to prevent copper oxidation, separate the soldered part from the non-soldered part of PCB and protect the surface of PCB, the design engineer will apply a special coating on the surface of PCB to form a protective layer with a certain thickness to block the contact between copper and air. This coating is called solder resist and the material used is solder resist paint. In order to facilitate maintenance and manufacturing, PCB usually needs to print small text on the board. Therefore, engineers added various colors to the solder resist paint, and finally formed a “colorful” circuit board.

  

  Why are green inks widely used?

  

  The color of solder resist mainly depends on the color of solder resist ink. Green ink is the most widely used and the cheapest in the market. In fact, the solder resist ink on the market is not limited to one kind of green, and there are many colors such as red, blue, purple, black and yellow, but green is the most common one. The main reason is that the use of green solder resist ink has the following advantages: it is convenient for optical positioning correction.

  

  The manufacturing process of the circuit board itself includes STM welding process, and this process needs to be tinned and finally verified by AOI. These processes need to be calibrated by optical positioning, and the green background color has a better recognition effect for the instrument. In the yellow room, the visual effect is better. The whole PCB product has to go through the processes of board making and SMT in the production process. Usually, when the circuit board is used in the production and processing of electronic products, there will be some processes that need to pass through the yellow room. According to the optical law, the green circuit board has a better visual effect in the yellow room, and it is easier to check the production of electronic products.

  

  It is beneficial for workers to observe the circuit board.

  

  At present, due to the production process and other problems, the quality inspection process of many lines still depends on the naked eye observation and identification of workers (of course, flying needle testing technology is mostly used at present). It is very tiring to keep staring at the board under strong light. Using green as the background color of circuit board can reduce the damage of strong light to workers’ eyes, so most manufacturers in the market use green PCB at present.

  

  Environmental protection and low cost.

  

  Because the circuit board needs to be recycled at high temperature when it is discarded, and the green solder resist ink will not release toxic gases, recycling is more environmentally friendly. Thanks to the above advantages, the adoption rate of green solder resist ink is the highest and the production process is the most mature. Therefore, the cost of using green solder resist ink to produce circuit boards is also lower.

Sapphire in Montana Rebirth After Disaster!

  The history of the American West tells of pioneers searching for gold and other precious metals. But when these intrepid adventurers arrived in western Montana in search of gold, they accidentally found a very strange and shiny stone. It was sapphire. Before the discovery of sapphires, pioneers did not know much about precious stones, which were considered worthless by ordinary gold seekers. More than 100 years later, the Montana mine¨s legacy value was discovered by a few miners who started a company and turned to sapphire deposits.For the immediate pressure, jewelry With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://tonglinring.com/” target=_blank>

  

  The biggest challenge is Montana¨s rugged terrain, a harsh winter that only allows construction for about six months a year, and a lack of water. Wildfires forced the closure of mines several times in 2017. Despite the challenges,2018 was the company¨s third year of full production, with more than 100 kilograms of sapphire raw stone recovered. In 2018, the company purchased more beneficiation equipment for the mine, which can process more ore and produce more sapphires each year. The company also pays special attention to the protection of the mine field environment and has implemented a strict mine environmental restoration program. They only allowed a single mining operation in a five-acre area, and after the mine environment was restored there was hardly any trace of mining. Special water filters have been installed to purify and treat mineral processing wastewater, supposedly to protect the river¨s native trout.

  

  Sapphires here come in a variety of colors (Photo 1), including blue, brilliant yellow, orange and pink, but Montana rubies are very rare. Some sapphires come out of mining with a beautiful natural color, but most require heat treatment to change the color. Less than 1% of mined sapphires can be processed into 2-6 carat faceted gems, most of which are cut into 0.25-0.99 ct finished products. Last year the mine yielded a 64.14 ct rough sapphire, the largest quality sapphire ever found in Montana.

  

  The company has no problem finding a market for large-grained sapphires. The biggest challenge is selling large numbers of small and medium-sized stones. The company is establishing trade relationships with jewelry processors in the hope of finding a Montana sapphire market within 0.5 ct. Their primary markets are in the United States and Canada. But they also see a growing international market and are using social media platforms to export to customers from India, Hong Kong, Sri Lanka and Europe. Montana Sapphire even has a presence in sapphire producing countries such as Australia, and with significant investment in mine infrastructure and a clearer marketing strategy, the Montana Sapphire story will continue to grow.

Here are some tips on how to protect sapphire jewelry.In the eyes of industry experts, jewelry manufacturer Indeed, it has great development potential, which makes many investors more interested. https://tonglinring.com/

  

  Daily Wear Precautions

  

  1. Avoid collisions

  

  Sapphire, although hard, is not indestructible. In daily wear, sapphire jewelry should be avoided from colliding with other hard objects, so as not to cause scratches on the gem surface or cracks inside. For example, when performing physical labor or exercise, it is best to remove sapphire jewelry and put it in a jewelry box for safekeeping.

  

  When worn with a harder gemstone such as a diamond, the sapphire may also be scratched. Therefore, try to avoid wearing sapphire jewelry with other high-hardness gems at the same time.

  

  2. Prevent chemical erosion

  

  Sapphire jewelry should be kept away from chemicals, such as perfume, cosmetics, cleaning agents, etc. These chemicals may cause corrosion to the surface of the sapphire, affecting its luster and transparency. After using cosmetics, perfume and other items, you should wait for a period of time to fully volatilize before wearing sapphire jewelry.

  

  When swimming, bathing or doing housework, sapphire jewelry should also be taken off to avoid contact with soap, detergent and other chemicals.

  

  3. Pay attention to temperature changes

  

  Sapphire is more sensitive to temperature changes, should avoid sapphire jewelry exposed to extreme temperature environment. For example, do not put sapphire jewelry in the sun for a long time or close to heat sources, such as heating, furnaces, etc. High temperatures may cause the sapphire to discolor or crack inside.

  

  In cold weather, attention should also be paid to protecting sapphire jewelry to avoid sudden temperature changes. For example, when entering a warm room from a cold outside, do not immediately expose sapphire jewelry to a high temperature environment, you can first put it in your pocket, so that it gradually adapt to temperature changes.Sapphire, although hard, is not indestructible.
