What is Porosity?
Porosity is a phenomenon that occurs in materials, especially castings, as they change state from liquid to solid during the manufacturing process.
Explaining Casting Porosity
Casting porosity is found in cast metal components, particularly aluminium and magnesium die castings. Discover the types of porosity and browse our solutions.
The Vacuum Impregnation Process Explained
The impregnation process involves five key stages: 1. Part preparation 2. Impregnation 3. Drain 4. Cold wash 5. Hot cure – learn more about the process here
Porosity in Powdered Metal Components
Powdered metal parts are impregnated to improve their material properties for: Improved machining, surface coating pre-treatment, pressure integrity.
Controlling Porosity for Electronic Components
Electronic components need to protecting against water or chemical ingress which can cause corrosion. Ultraseal impregnation offers a permanent solution.
