A welded seam or insertion tube sealing process creates seals that can withstand various types of requirements for certain liquid types or air pressures. An example of this would be for the medical industry, where ensuring the seal is airtight and fluid-tight is crucial. [7] An IV drip bag, showing a RF weld around the perimeter.
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...

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 ...
Induction sealing also offers advantages when sealing to glass: Using a conduction sealer to seal a simple foil structure to glass gives no tolerance or compressibility to allow for any irregularity in the glass surface finish. With an induction sealer, the contact face can be of a compressible material, ensuring a perfect bond each time.
Heat seal connectors are used to join LCDs to PCBs in many consumer electronics, as well as in medical and telecommunication devices.. Heat sealing of products with thermal adhesives is used to hold clear display screens onto consumer electronic products and for other sealed thermo-plastic assemblies or devices where heat staking or ultrasonic welding are not an option due to part design ...
Friction tube – the tube would have a lanyard attached, with length proportional to the size of the gun, which when pulled caused friction inside the tube which ignited a powder charge, much like striking a match. Single-use. Originally of "copper" and "quill" types, replaced by the "T" tube by the late 1890s.
The typical machine is loaded with a continuous flat roll of plastic film, which has usually had labeling and artwork applied. Plastic is the most commonly used packaging material in the food industry, but the technology can be used to form continuous metallized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods.
