Porosity Sealing - Process

Process

Porosity sealing is a four step process:

  1. Air within the pores is expanded under reduced pressure (vacuum).
  2. Pressure reversal (adding pressure outside the part) saturates pores with monomer.
  3. Excess monomer is rinsed from the exterior surfaces of the part.
  4. The liquid monomer within the porosity is polymerized into a solid to seal the passage.

Famous quotes containing the word process:

    It is part of the nature of consciousness, of how the mental apparatus works, that free reason is only a very occasional function of people’s “thinking” and that much of the process is made of reactions as standardized as those of the keys on a typewriter.
    John Dos Passos (1896–1970)

    Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.
    Robert Bly (b. 1926)

    come peace or war, the progress of America and Europe
    Becomes a long process of deterioration—
    Robinson Jeffers (1887–1962)
