The short version goes something like this: First there's the research into new methods, like nitrogen injection, or vacuum molding, which might take a year or two.
It is made of 2,700 boxy diamond-shaped modules of white plastic, each vacuum molded to have an inverted pyramidal front.
A buddy who worked in three-dimensional mapping taught him a thing or two about vacuum molding, and, not long after Mr. Doyel settled in New York, he found himself in the business of making molds for cheap, reproducible stuff — for example, an image of Santa on his sleigh that could be lighted from within and displayed on the lawn.
The drum shell structure was fabricated by wet lay-up and a vacuum molding technique.
Pillows and vacuum molds were used for patient immobilization: 4-dimensional CT simulation was carried out (GE LightSpeed RT 16; GE Healthcare, Waukesha, WI, USA) with free breathing.
To obtain water-free samples, the samples were held in the drying box during 3 days at the temperature of 115 °C, and then, they were encapsulated in the vacuum press mold.
An experimental procedure was designed to realistically characterize the compaction behavior of e-glass fabric preforms during initial application of vacuum and mold filling stages of Vacuum Infusion (VI).
In addition, the composite housing with monolithic grid-stiffened frame was fabricated by co-curing through vacuum bag molding method.
3D spacer knitted fabrics with four different cross-sections were infused by epoxy resin through the vacuum infusion molding process.
Two different manufacturing processes, namely vacuum bag molding and thermo-compression, were used to manufacture the structures.
