2. Heat sealer - Wikipedia

   en.wikipedia.org/wiki/Heat_sealer

   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 ...

3. List of polyurethane applications - Wikipedia

   en.wikipedia.org/wiki/List_of_polyurethane...

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

4. Radio-frequency welding - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_welding

   The amount of heat generated by friction in the material is dependent on field strength, frequency, dipole strength, and free volume in the material. [1] Since the main driving force for dielectric heating is the interaction of the dipole of a molecule with the applied electrical field, RF welding can only be conducted on dipole molecules.

5. Glass-ceramic-to-metal seals - Wikipedia

   The white opaque "glue" between the panel and the funnel of a colour TV cathode ray tube is a devitrified solder glass based on the system PbO – ZnO – B 2 O 3.While this is a glass-ceramic-to-glass seal, the basic patent of S.A. Claypoole considers glass-ceramic-to-metal seals as well.

6. Seal (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Seal_(mechanical)

   The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. [1] A stationary seal may also be referred to as a 'packing'. Seal types: Induction sealing or cap sealing; Adhesive, sealant; Bodok seal, a specialized gas sealing washer for medical ...

7. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   Hot gas welding, also known as hot air welding, is a plastic welding technique using heat.A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic.
