Process
Porosity sealing is a four step process:
- Air within the pores is expanded under reduced pressure (vacuum).
- Pressure reversal (adding pressure outside the part) saturates pores with monomer.
- Excess monomer is rinsed from the exterior surfaces of the part.
- The liquid monomer within the porosity is polymerized into a solid to seal the passage.

Famous quotes containing the word process:
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
“Healthy parenting is nothing if not a process of empowerment. As we help to raise our children’s self-esteem, we also increase their personal power. When we encourage them to be confident, self-reliant, self-directed, and responsible individuals, we are giving them power.”
—Louise Hart (20th century)
