The vacuum sealing unit has the following characteristics:
1.Good sealing performance:
Vacuum environment maintenance: The vacuum sealing unit needs to have a high degree of sealing to ensure stable vacuum during the vacuuming process. This is crucial for the quality of sealing, as only under good sealing conditions can impurities such as air and moisture be expelled as much as possible, preventing the formation of bubbles or pores in the sealing material. For example, in the encapsulation of electronic components, if the sealing is not good and external air enters, it can cause problems such as decreased insulation performance and susceptibility to moisture in the encapsulated electronic components.
Preventing leakage of sealing material: During the sealing process, the sealing material needs to be accurately injected into or around the sealed object. Good sealing can prevent the sealing material from leaking into unnecessary areas, ensuring the accuracy and integrity of the sealing.
2.Accurate measurement and control:
Accurate measurement of sealing materials: It can precisely control the amount of sealing materials used, ensuring that the amount of sealing materials used for each sealed product remains consistent. This is very important for ensuring the quality stability of the product, especially in some application scenarios that have strict requirements for the amount of potting materials used, such as electronic component packaging. Too much or too little potting material can affect the performance of the product.
Adjustable process parameters: precise control of process parameters such as sealing speed, pressure, and time. According to different product requirements and sealing material characteristics, operators can flexibly adjust these parameters to achieve the best sealing effect. For example, for high viscosity potting materials, higher pressure and slower potting speed may be required; For some products that require high sealing accuracy, the sealing time needs to be precisely controlled to ensure that the sealing material can fully fill every corner.
3.Efficient degassing function:
Exhaust air and impurities: Sealing in a vacuum environment can effectively eliminate the air inside the sealed object, as well as the gases and impurities in the sealing material. The presence of air can cause bubbles to form inside the sealed product, reducing its mechanical strength, insulation performance, and other properties. By vacuuming, the sealing material can be fully filled into the interior of the sealed object, improving the quality and reliability of the product.
Improving the adhesion of the sealing material: After removing gases and impurities, the sealing material can better bond with the surface of the sealed object, enhance the adhesion of the sealing material, and make the sealed product more firm, less prone to problems such as delamination and cracking.
4.Wide applicability:
Sealing with multiple materials: Suitable for various types of sealing materials, such as epoxy resin, polyurethane, silicone rubber, etc. These sealing materials have different physical and chemical properties, which can meet the sealing needs of different products. For example, epoxy resin has good insulation properties and mechanical strength, and is commonly used for sealing electronic components; Silicone rubber has good flexibility and high temperature resistance, making it suitable for applications that require high temperature changes.
Encapsulation of various products: widely used in the fields of electronics, electrical, automotive, aerospace, etc. For example, in the field of electronics, vacuum sealing units can be used to package electronic components such as integrated circuits and sensors; In the automotive field, electronic control modules, sensors, and other components that can be used to encapsulate automotive engines; In the aerospace field, it can be used to encapsulate key components such as electronic equipment and navigation systems of aircraft.
5.High degree of automation:
Easy to operate: Modern vacuum sealing units are usually equipped with automated control systems. Operators only need to set the relevant process parameters, and the equipment can automatically complete a series of operations such as vacuuming and sealing, greatly reducing the difficulty and labor intensity of operation.
High production efficiency: Automated operations can achieve continuous and rapid sealing, improving production efficiency and suitable for large-scale production needs. At the same time, the automation control system can also monitor and control the sealing process in real time, detect and solve problems in a timely manner, and ensure the stability and reliability of production.
