Count the Different Production Techniques of Medals and Badges_

  The varieties of medals and badges are generally determined by their different production processes. The most common production processes for medals and badges include enamel, paint, imitation enamel, stamping, screen printing, die-casting, etc. Today, we will introduce different production processes and their characteristics.In view of the actual needs of society, custom medals for awards We need to change some original problems to better serve the society and benefit people. https://www.karonmetal.com

  

  

  1. Production process – enamel

  

  As the most advanced coloring process, enamel is said to have been first recorded in the Yuan Dynasty, was most refined in the Ming Dynasty, and was already flourishing in the Qing Dynasty. Enamel badges, also known as cloisonn└ badges, are colored with enamel powder on red copper (purple copper). The color is dark and single, the cost is high, and it is fragile and cannot be knocked or faded by gravity. However, because of its strong color fixation and long preservation time, it is generally chosen to make commemorative medals that need to be preserved for a long time without fading, badges, medals, medals, etc. for state organs, military police, etc.

  

  2. Production process – imitation enamel

  

  Imitation enamel badges are generally colored with resin paint. The color is brighter than enamel and can be made of copper, zinc, alloy, etc. as the base material, with a strong sense of concave and convex. Soft enamel badges and resin are coloring materials developed by foreign experts. The surface can be plated with various metal colors such as gold and nickel. It is smooth and delicate, giving people a very noble feeling. It is suitable for high-end badge customization, mid-to-high-end commemorative medal production, commemorative medals and other exquisite products.

  

  How to distinguish enamel from imitation enamel: Real enamel has a ceramic texture, less color selection, and a hard surface. Puncture the surface with a needle will not leave marks, but it is easy to break. Imitation enamel is soft, and a needle can pierce the fake enamel layer. The color is bright, but it cannot be preserved for a long time. After three to five years, the color will turn yellow after high temperature or ultraviolet radiation.

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.consequently biodegradable mailing bags I also got a lot of attention and wanted to join the ranks. 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.

Analysis of the difference between the flat top and heat sink top of the 400G optical module

  Recently, a sales partner encountered a difficult problem. The optical module received by the customer could not be used. After much research, the reason was found. It turned out that the customer purchased an optical module with a heat sink, which did not match the existing network card slot. What is the difference between the flat top and the heat sink top of the optical module? How to choose when using it? Let’s follow the editor to take a look!according to 400g aoc cable Industry veterans said that its development will still be in a good situation. https://www.3coptics.com/

  

  1. The difference between the flat top and the heat sink top of the optical module

  

  The flat top and heat sink top in the optical module usually refer to two different structures in the optoelectronic device:

  

  Flat-top: Flat-top structure usually refers to the flat top structure of the laser or optical transmitter in the optical module. This design allows light to propagate and focus more easily, which is conducive to more efficient transmission of optical signals in optical fibers or other transmission media. The flat-top design can improve the coupling efficiency and transmission efficiency of light, and is more common in some high-performance optical communications or optical sensors.

  

  Heatsink-top: Heatsink-top structure usually refers to the top design of laser or optoelectronic device with heat sink. These heat sinks are usually used to effectively dissipate heat to keep the device operating temperature within a safe range. In high-power or high-density applications, the device may generate a lot of heat, which needs to be transferred to the surrounding environment through the heat sink to prevent the device from overheating and damage. Therefore, the heat sink design is crucial for the long-term stable operation of the optical module.

  

  400g optical module

  

  2. How to choose the flat top and heat sink top of the optical module

  

  With the increase of transmission rate, the size of the optical module is gradually miniaturized, and the requirements for internal optical devices are getting higher and higher. It is very necessary to solve the heat dissipation problem. The flat top and heat sink top of the optical module each have their advantages. Which one is better depends mainly on the transmission rate, interface type, packaging method and specific application scenarios and requirements.

  

  Transmission distance and rate requirements: If your application requires long-distance high-speed transmission, the flat-top structure may be more suitable because it is conducive to improving the coupling efficiency and transmission efficiency of light. For short-distance or low-speed transmission, the heat sink top structure can be considered more.

  

  Thermal management requirements: If the laser or optoelectronic device in your application needs to handle a lot of power or high-density energy, the heat sink top structure may be more important because it is conducive to effective heat dissipation, thereby maintaining the stable operation of the module and preventing overheating from causing performance degradation or damage. Especially in applications such as high-power optical communications or lidar, good thermal management is essential.

  

  Cost and complexity: The flat-top version of the optical module has a simple design and no additional heat sink structure, because it focuses on the light transmission efficiency, while the heat sink top structure may require a more complex design and manufacturing process to ensure good heat dissipation performance. Therefore, you need to weigh these two options when considering cost and complexity.

  

  Environmental conditions: Consider the environmental conditions in which your application will operate. If the ambient temperature is high or there may be other heat sources, good heat dissipation may be more important.

  

  Reliability and stability requirements: If your application has high requirements for long-term stable operation of the device, it may be more appropriate to choose a heat sink top structure that can provide good thermal management.

Some Tips on Medal Making

  Metal medal production is a well-made metal medal. According to different shapes, it can be divided into: medals, medals, and award plates. Common medal materials: made of aluminum, iron, zinc alloy, copper, gold, silver and other materials. There are also stone, wood, resin, organic, and even several kinds of composite materials.As it happens, many people are killed custom medals And bring more benefits, make it flourish, and promote the industry greatly. https://www.karonmetal.com

  

  Materials for making metal medals.

  

  High-end medals:

  

  1. Breakthrough in technology, make race medals custom in Shanghai Yibi Mint, use advanced and precise production technology and production process, so that this medal shows its original medal value orientation in high-end and uniqueness.

  

  2. Breakthrough in design, exquisite design and technology, improve the value of the medal.

  

  Process of making metal medals

  

  In the medal making industry, what kind of production technology and production process are used to make the medal will make this medal show its original medal value orientation in high-end and uniqueness. Among them, the electroplating process is divided into many categories.

  

  Electroplating process – chrome plating

  

  Chromium is a silvery-white metal with a slight sky blue tint. The chrome layer has high hardness, good wear resistance, strong reflective ability, and good heat resistance. There is no obvious change in gloss and hardness below 500<C; it begins to oxidize and discolor when the temperature is greater than 500<C; it begins to soften when it is greater than 700<C. Due to the excellent performance of the chrome plating layer, it is widely used as a protective, decorative coating system’s surface layer and functional coating.

  

  Custom made trophies and medals.jpg

  

  Electroplating process – copper plating

  

  Copper is easy to oxidize, and the oxidized patina is no longer conductive; copper plating is easy to lose its luster in the air, and reacts with carbon dioxide or chloride to form a layer of basic copper carbonate or copper chloride film on the surface. It will generate brown or black copper sulfide when it is exposed to sulfides. Therefore, as a decorative copper plating layer, an organic coating layer needs to be coated on the surface.

  

  Price of metal medal production

  

  The material is very important in the production of metal medals. One cent for one product has always been the value law of any industry and any commodity. It is difficult to get high-end products at a very low price.
