The overall dispensing effect of dispensing machine mainly includes many factors, such as dispensing needle, amount of glue needed for dispensing, distance between needle and dispensing product, pressure value set by dispensing machine, viscosity of glue used for dispensing and curing time of glue, etc. These factors will affect the dispensing effect. The overall effect of dispensing process. How to operate dispensing machine to adjust the values of various aspects to make it have better dispensing effect, first of all, we need to understand the following aspects:
