Die Castings Vacuum impregnation was first developed to seal die casting porosity. The process is used to seal die casting porosity in order to prevent fluids or gases from leaking under pressure.
VPI Technology As demand grows for more reliable, efficient, and long-lasting electrical equipment, the importance of vacuum pressure impregnation (VPI) technology becomes increasingly clear.
Power Transmission & Distribution Moisture in transformers is a major threat. It weakens insulation, leading to potential breakdowns, short circuits, and reduced lifespan. Vacuum impregnation removes moisture, ensuring optimal performance and reliability.
Electronics The surge in electronic components has made vacuum impregnation the best process to seal leak paths and prevent corrosion.
Powder Metal The use of vacuum impregnation in powder metal expands beyond sealing porosity. The process also reduces corrosion, improves machinability, and enhances surface finishing.
3D Printing 3D printing has streamlined the product development cycle. However, parts created through the process are susceptible to the same porosity that plagues those created through more traditional processes. Vacuum impregnation is used on 3D printed parts to seal leak paths and improve part integrity.
Graphite Graphite demand is skyrocketing to meet hybrid and electric vehicle use. Porosity is inherent in graphite, and vacuum impregnation is used to the porosity to ensure the parts are pressure tight.
