Product Specifications

Technical details and manufacturing context for Pressure System

Definition
The pressure system is a critical component of vacuum impregnation systems used in manufacturing processes. It functions by generating and regulating positive pressure after the vacuum phase, forcing sealants, resins, or other impregnating materials into the microscopic pores and voids of materials such as castings, powder metal parts, or electronic components. This ensures complete penetration and sealing of porosity to improve structural integrity, prevent leakage, or enhance surface properties.
Working Principle
After the vacuum chamber evacuates air from the workpiece's pores, the pressure system introduces impregnating fluid. It then applies controlled positive pressure (typically hydraulic or pneumatic) to the fluid reservoir or chamber, forcing the fluid under pressure into the evacuated pores. The system maintains this pressure for a specified duration to ensure complete filling before releasing and allowing excess fluid to be removed.
