The industry that produces and distributes machinery for vacuum pressure impregnation (VPI) processes is known as equipment for the vacuum pressure impregnation (VPI) market. VPI is mainly used to enhance the durability and insulation properties of various materials, especially in industries such as automotive, aerospace, and electrical manufacturing. This device makes it easier to use porous materials such as resins or other sealing compounds (for example, metals, ceramics or composite materials) under controlled vacuum and pressure conditions to ensure that the components have no air pockets, voids or moisture.
By type
Wet
Drying
The equipment in the vacuum pressure impregnation (VPI) market is mainly divided into two types: wet and dry. The wet section involves the use of liquid resins or impregnating agents, which are introduced into the voids of the material under vacuum and pressure. This method is typically used to impregnate metals or composite materials (such as metals or composites) to enhance their mechanical properties and lifespan.
On the other hand, the dry section utilizes a dry impregnation process, during which the material is subjected to vacuum and pressure without the addition of liquid. This method is typically used in applications that require minimal use of resin or impregnating materials to maintain a solid state.
Each type has unique advantages, depending on the application, such as enhanced durability, resistance to environmental factors or cost-effectiveness. For high-performance applications that require thorough impregnation, wet VPI is usually the preferred choice, while dry VPI can be selected to avoid the process of using liquid resin.
