I. Disadvantages of an Unwelded Insulation Box

 (1) Poor Thermal Insulation Performance

In an unwelded insulation box, there are gaps at the joints of various parts. These gaps lead to air convection, making it easy for the outside hot air to enter the inside of the insulation box, while the cold air inside the box will escape, greatly reducing the thermal insulation effect. In scenarios where low temperature needs to be maintained for a long time, such as transporting vaccines and fresh food, an unwelded insulation box is difficult to meet the requirements and may cause the items to deteriorate and be damaged.

 (2) Unstable Structure

Since there is no welding for reinforcement, the various components of the insulation box are just simply spliced together, and the connection is not firm enough. During handling and moving, when subjected to external collisions or squeezes, it is very likely to become loose, deformed, or even fall apart. This not only affects the normal use of the insulation box but may also damage the items inside the box.

(3) Poor Sealing Performance

The unwelded splicing method cannot achieve a good sealing effect, and dust, moisture, etc. can easily enter the inside of the insulation box from the gaps. For some items with high environmental requirements, such as electronic components and precision instruments, the intrusion of dust and moisture may affect their performance and service life. Moreover, poor sealing will also cause the odor inside the insulation box to escape, affecting the surrounding environment.

II. Advantages of Vibration Friction Welding

 (1) Excellent Thermal Insulation Performance

Vibration friction welding enables all parts of the insulation box to be closely integrated, forming a seamless connection. This connection method effectively prevents air convection, reduces heat transfer, and greatly improves the thermal insulation performance of the insulation box. It can maintain the stability of the temperature inside the box for a long time, providing a good storage environment for items.

 (2) High - strength Structure

The welded insulation box becomes a monolithic structure with high strength and stability. It can withstand greater external impacts and squeezes and is not easily damaged during handling and transportation. Even if it is subjected to a large collision, it can ensure the safety of the items inside the box, reducing losses caused by the damage of the insulation box.

(3) Good Sealing Performance

Through vibration friction welding, the sealing performance of the insulation box has been significantly improved. It can effectively prevent the intrusion of external factors such as dust and moisture, providing a clean and dry storage environment for the items inside the box. At the same time, good sealing can also prevent the odor inside the box from escaping, keeping the surrounding environment fresh.

 (4) Beautiful Appearance

The surface of the welded insulation box is smooth, without obvious splicing marks, and the appearance is more beautiful. This not only enhances the overall image of the product but also meets the usage requirements of some occasions with high appearance requirements. Moreover, the improvement of the appearance also helps to improve the market competitiveness of the product.
