According to Plastipedia, one benefit of vacuum forming is its “comparatively low cost tooling.” Because it uses low pressures, it requires a smaller quantity of less sophisticated tools, which also means that molds can be produced from relatively inexpensive materials.

Some of the substances used as friction materials are paper, elastomerics, graphitics, and sintered metals. A wide variety of other materials are also used, such as ceramics, advanced fibers and different metal alloys. Asbestos was actually a widely used friction material until its usage was banned.

A vacuum tube consists of two or more electrodes in a vacuum inside an airtight envelope. Most tubes have glass envelopes with a glass-to-metal seal based on kovar sealable borosilicate glasses, though ceramic and metal envelopes (atop insulating bases) have been used.
