1. Differences in the amount and type of adhesive used in dispensing and potting
Potting typically uses a large amount of adhesive for encapsulation, while dispensing uses small or micro-amounts of adhesive. Adhesives include single-component and two-component types. Single-component adhesives are frequently used in dispensing processes, while two-component adhesives are usually used in potting processes.
2. Differences in the adhesive supply system and application characteristics of dispensing and potting
Automatic dispensing machines usually control the adhesive flow by controlling air pressure, while potting equipment uses gear pumps, screw pumps, piston pumps, and other pumps to quantitatively meter, proportion, and mix the two adhesives before potting them into the product. Dispensing is suitable for applying adhesive to points, lines, circles, and various irregular trajectories on products, while potting is suitable for sealing and encapsulation of products, with waterproof potting usually based on fixed points.
3. Differences in the application fields of dispensing and potting
Dispensing is typically used for dispensing adhesive on small products, such as mobile phone cases, mobile phone TP screens, walkie-talkies, speakers, audio equipment, PCB circuit boards, electronic components, electric toothbrushes, and other products. Potting is typically used for sealing, waterproofing, and moisture-proofing of products such as LED power supplies, waterproof power supplies, driver power supplies, capacitors, transformers, ignition coils, filters, wall washers, LED flexible light strips, and linear lights.
