The working principle of vacuum dipping equipment is to immerse the workpiece in paint under vacuum state, remove the gas and moisture inside the workpiece by vacuuming, so that the paint can more easily penetrate into every tiny corner of the workpiece, thereby achieving a better coating effect. The specific process is as follows:
Vacuuming: Put the workpiece to be processed into a vacuum container, and remove the gas and moisture inside the workpiece by vacuuming to form a vacuum state.
Painting: Under vacuum state, immerse the workpiece in paint, and the paint enters the gap and inside of the workpiece under the action of pressure difference.
Pressure balance: When the pressure inside the workpiece is balanced with the external pressure, stop vacuuming to make the paint evenly distributed inside the workpiece.
Curing: Finally, the workpiece after dipping is cured to ensure that the paint is completely cured.
