How the vacuum press machine works to cover the membrane on the board


The vacuum press machine is an essential tool for applying membrane coating onto a board. The process involves the use of a vacuum to create a pressure differential between the membrane and the board, which results in a tight and durable bond. In this article, we will discuss the working mechanism of the vacuum press machine and its application in membrane coating.


The vacuum press machine consists of two main components: the vacuum bag and the vacuum pump. The vacuum bag is made of a flexible material that can be sealed around the board to create an airtight chamber. The vacuum pump is used to remove the air from the chamber, creating a vacuum that pulls the membrane onto the board.


The process of applying a membrane coating using the vacuum press machine starts with preparing the board. The board needs to be clean, dry, and free of any debris or dust. Next, the membrane is cut to size and placed onto the board. The vacuum bag is then placed over the board and sealed around its edges, creating an airtight chamber.


The vacuum pump is turned on, and air is removed from the chamber, creating a vacuum. As the air is removed, the membrane is pulled onto the board, conforming to its shape and contours. The vacuum press machine applies even pressure across the entire surface of the board, ensuring a tight and durable bond between the membrane and the board.


Once the vacuum press machine has completed its cycle, the vacuum is released, and the bag is removed. The excess membrane is trimmed away from the edges of the board, leaving a clean and precise finish.


In conclusion, the vacuum press machine is an essential tool for applying membrane coatings onto boards. Its working mechanism involves creating a pressure differential between the membrane and board,

resulting in a tight and durable bond. The process is straightforward and can be completed quickly, making it an ideal solution for large-scale production.
