In VRLA battery manufacturing, a heat sealing machine is employed for the efficient sealing process. This automated machine performs the following steps: 1.Automatic Gripping: The heat sealing machine automatically grabs the lead acid battery cover, ensuring precise positioning for the sealing operation. 2.Heating and Sealing: The machine heats the designated sealing part of the battery cover using a specialized heating template. The heat causes the sealant material to melt, preparing it for the next step. 3.Hot Melt Time: The battery cover remains in contact with the heating template for a specific period, allowing the sealant to reach an optimal melting point. This ensures a secure bond during the sealing process. 4.Pressing and Sealing: Upon completion of the hot melt time, the Sla battery cover, along with the tank of the battery shell, is pressed together. This pressure creates a tight and reliable seal between the battery cover and the tank. By automating these steps, the heat sealing machine streamlines the production process for sealed lead acid batteries. It ensures consistent and efficient sealing, contributing to the overall quality and reliability of the batteries produced.
