This appeared to him so awfully mysterious, and impressed him so immensely, that what he saw and heard after he got on deck were mere trifles in com- parison.
of the Czech Republic, is now capable of performing fully 3-D simulation of the blow molding process using fully 3-D parison geometry.
The package includes the MACO Breeze lie parison control and an operator interface based on Microsoft CE.
Extrusion blow molding consists of parison formation, pinch-off, and blow-up stages.
The parison is captured on both ends, between the preceding mould and the head, and so is always the same length.
For simple and short bends, the duct can be blow molded without the need for convoluted sections by simply tilting the axial axis of the duct relative to the parison axis; however, this method may require a secondary machining operation to even out some wall thickness, and in some areas of the blow molded duct, wall thickness distribution is sacrificed for manufacturing simplicity.
But he has a near nor mal life expectancy and full awareness of his dis abilities and of the com parison between himself and others.
The extruded parison is cut to length and is robotically manipulated so that it fits between the open mold where the carrier is.
The forming of glass containers by the "press and blow" process can be divided into five main steps: gob formation at the feeder, transfer and loading of the gob into the blank, pressing of the parison, inversion of the parison into the blow mold, and the reheat and final blowing of the container.
Furthermore, a method that focuses on visual likeness without considering context, ignores how "what looks like the same object can be structured into two different cultures in such a completely different way that the surface likeness is insignificant in com parison with the deeper symbolic differences" (25).
With parison programming, the thickness of the bottle can be varied throughout its length, allowing more plastics to be used in areas needing greater strength, such as the neck.
