   FKMs (FPMs), is used for demountable vacuum seals. It is better for lower pressures than nitrile rubber and chemically much more inert. It is bakeable to 200 °C. FFKMs very low out-gassing similar to PTFE and withstands baking temperatures up to 300 °C, while chemically one of the most inert sealing elastomers.

3. Vacuum packing - Wikipedia

   en.wikipedia.org/wiki/Vacuum_packing

   External vacuum sealers involve a bag being attached to the vacuum-sealing machine externally. The machine will remove the air and seal the bag, which is all done outside the machine. A heat sealer is often used to seal the pack. Typically these units use a dry piston vacuum pump which is often considered a "maintenance-free" pump.

4. Vacuum flange - Wikipedia

   en.wikipedia.org/wiki/Vacuum_flange

   A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other. Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum's chamber.

5. Packaging machinery - Wikipedia

   For example many packages include heat seals to prepare or seal a package. Heat sealers are needed, even in slow labor-intensive operations. With many industries, the effectiveness of the heat seal is critical to product safety so the heat sealing operation must closely controlled with documented Verification and validation protocols.

6. Blow fill seal - Wikipedia

   en.wikipedia.org/wiki/Blow_fill_seal

   BFS-packaged eye drops for single use. Blow-Fill-Seal, also spelled as Blow/Fill/Seal, in this article abbreviated as BFS, is an automated manufacturing process by which plastic containers, such as bottles or ampoules are, in a continuous operation, blow-formed, filled, and sealed.

7. Glass-to-metal seal - Wikipedia

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
