Dispensing is a common process also known as sizing, coating, potting, dripping, and so on. Its main purpose is to apply, pot or drip electronic glue, oil or other liquid adhesive substances onto products to achieve adhesion, potting, insulation, fixation, surface smoothness and other functions. Dispensing is widely used in various fields, including electronics manufacturing, automotive industry, medical devices, aerospace, and so on. Dispensing can be done manually or with the help of machines and equipment, such as automated dispensing machines. Automated dispensing machines are able to improve productivity and accuracy by controlling the speed, pressure and path of the glue application to achieve precise glue distribution. The application of dispensing technology makes the products have better adhesion, sealing and appearance quality, to meet the requirements of different industries on product performance and quality.
