Even in the face of the impact of the new crown pneumonia epidemic, the pace of Asia-Pacific economic integration has not stopped. On January 1, 2022, the Regional Comprehensive Economic Partnership (RCEP) came into effect, marking the launch of the world's most populous and largest free trade zone in terms of economic and trade scale. Whether it is economic recovery or institutional building, the Asia-Pacific region provides new impetus to the world. With the gradual entry into force of RCEP, tariff barriers and non-tariff barriers in the region will be significantly reduced, and Asian economies, RCEP countries and CPTPP countries will continue to increase their dependence on Asia for trade in goods.

In addition, the "Report" also pointed out that financial integration is an important part of Asian regional integration and economic and trade integration. The process of financial integration of Asian economies will help all economies work together to deal with international challenges and jointly maintain regional and global financial stability. The growth rate of foreign investment in Asian economies in 2020 is 18.40%, which is 4% higher than the growth rate in 2019, indicating that the Asian financial market remains relatively attractive during the epidemic. Japan is the only Asian economy among the top 10 economies by global portfolio investment. China is one of the major economies with the fastest portfolio growth (both outflows and inflows) in recent years.

The "Report" believes that in general, the Asian economy will still be in the process of recovery in 2022, but the growth rate may converge. The development of the new crown pneumonia epidemic, the geopolitical situation after the conflict between Russia and Ukraine, the rhythm and intensity of monetary policy adjustment in the United States and Europe, the debt problems of some countries, the supply of key primary products, and the change of government in some countries will become the key factors affecting Asian economic growth.

Second, the key points of choosing hinges
1. The materials used are corrosion-resistant and the quality should be thick. When buying hinges, you should choose according to the environment and material characteristics. When buying, you can also weigh the weight of similar products of different brands, and products with thick quality are better. Steel hinges are easy to rust and are not suitable for use in humid environments; copper hinges have corrosion resistance and antibacterial functions, and are suitable for bathroom use; aluminum hinges have low strength and are generally thicker; stainless steel is decorative and functional They are all relatively good, and they are the products commonly chosen by many families, but be careful when buying products that are coated on the surface by merchants.

2. Smooth appearance and good surface treatment. Firstly, check whether the surface material of the hinge is smooth. If you see scratches or deformation, it means that the product is produced with waste; secondly, observe the surface treatment of the hinge carefully and make a sharp cut to see if you can see it. The yellow copper layer, or look inside the hinge cup, if the cup shows the same water performance or iron color, it proves that the electroplating layer is very thin and there is no copper plating. If the color and brightness of the cup are close to other parts, electroplating Pass. In general, a well-made hinge has a beautiful appearance and a small gap, which will be more reliable in use.

Gas springs are widely used in a variety of applications, including automotive, machinery, and furniture. Their primary purpose is to provide reliable support for lifting, lowering, and counterbalancing operations. Accurate measurement of gas springs is crucial to ensure proper functionality. In this article, we will explore different methods for accurately measuring gas springs, providing detailed instructions to ensure consistency and safety.

Method 1: Measuring the extended length

The extended length is a critical dimension of a gas spring, representing its fully extended position. To measure this length accurately, follow the steps outlined below:

1. Place the gas spring on a flat surface in its fully extended position, ensuring that it is stable and secure.

2. Use a measuring tape or ruler to measure the distance from the center of one end fitting to the center of the opposite end fitting. Make sure to measure from the center to ensure accuracy.

3. Record the measurement, noting the units (e.g., centimeters or inches) for future reference.

Method 2: Measuring the compressed length

The compressed length is another important dimension of a gas spring, representing its fully compressed position. To measure this length accurately, follow the steps outlined below:

1. Place the gas spring on a flat surface in its fully compressed position, ensuring it is stable and secure.

2. Use a measuring tape or ruler to measure the distance from the center of one end fitting to the center of the opposite end fitting. Again, be sure to measure from the center for accuracy.

3. Record the measurement, including the corresponding units.

Method 3: Measuring the stroke length

The stroke length refers to the difference between the extended length and compressed length of a gas spring. It indicates the total distance the gas spring can travel. To measure the stroke length accurately, follow the steps outlined below:

1. Measure the extended length and compressed length of the gas spring using the methods described above.

2. Subtract the compressed length from the extended length to determine the stroke length. This calculation provides the total travel distance of the gas spring.

3. Record the measurement and units accordingly.

Method 4: Measuring the force

The force of a gas spring represents the pressure it can exert when compressed or extended. Measuring the force accurately is crucial for determining the spring's suitability for specific applications. To measure the force, follow the steps outlined below:

1. Attach the gas spring to a fixed object, such as a wall or bench, ensuring it is securely fastened and cannot move during measurement.

2. Attach a fish scale or a force gauge to the free end of the gas spring, making sure it is accurately aligned with the direction of force.

3. Slowly compress or extend the gas spring, applying an even force until fully compressed or extended.

4. Take note of the reading on the fish scale or force gauge at any given point of travel. This reading represents the force exerted by the gas spring at that specific position.

5. Record the measurement, including the corresponding units.

Method 5: Measuring the diameter

The diameter of a gas spring significantly influences its strength and load capacity. To measure the diameter accurately, follow the steps outlined below:

1. Measure the distance between the center of the piston rod and the outer edge of the cylinder. Ensure the gas spring's components are properly aligned and the measurement is taken at the widest point.

2. Record the measurement, noting the units used for future reference.

In conclusion, accurate measurement of gas springs is essential to ensure their proper functioning and safety. By following the methods described above, you can accurately measure the different dimensions of gas springs, including the extended and compressed lengths, stroke length, force, and diameter. These measurements will facilitate the selection of the right gas spring for your application or the replacement of a faulty one. Always remember to follow the manufacturer's guidelines and consult a professional if in doubt. Proper measurement ensures reliable performance, enhances operational efficiency, and contributes to the overall success of your project or application.
