2. Hand warmer - Wikipedia

   en.wikipedia.org/wiki/Hand_warmer

   The release of heat is triggered by flexing a small metal disk in the hand warmer, which generates nucleation centers that initiate crystallisation. Heat is required to dissolve the salt in its own water of crystallisation and it is this heat that is released when crystallisation is initiated. [9] The latent heat of fusion is about 264–289 kJ ...

3. 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 ...

4. Induction sealing - Wikipedia

   en.wikipedia.org/wiki/Induction_sealing

   Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object (usually aluminum foil) by electromagnetic induction, through heat generated in the object by eddy currents. Induction sealing is used in many types of manufacturing.

5. Packaging machinery - Wikipedia

   en.wikipedia.org/wiki/Packaging_machinery

   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. Food ...

6. Hot-melt adhesive - Wikipedia

   en.wikipedia.org/wiki/Hot-melt_adhesive

   A hot glue gun loaded with a glue stick. Hot-melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun.

7. ThermaCare - Wikipedia

   en.wikipedia.org/wiki/ThermaCare

   ThermaCare is a type of Continuous Low-level Heat-wrap Therapy (CLHT), that activates upon contact with air, providing approximately eight hours of heat directly where the heat-wrap is applied. Thermacare heat-wraps are designed for specific applications, including neck or wrist pain, lower back pain, knee pain, and menstrual cramps.

8. Strapping - Wikipedia

   en.wikipedia.org/wiki/Strapping

   Manual sealers for plastic strap always use a seal and a compression (serrated seals) or crimp joint (smooth-faced seals). Automatic hand tools are used for higher-volume applications. Automatic tools can be powered by an electric battery, or by compressed air. Automatic hand tools for plastic strap use a friction weld.

9. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   A variety of heat sealers is available to join thermoplastic materials such as plastic films: Hot bar sealer, Impulse sealer, etc. Heat sealing is used for many applications, including heat seal connectors, thermally activated adhesives, and film or foil sealing. Common applications for the heat sealing process: Heat seal connectors are used to ...
