2. Ask about the configuration. This configuration does not refer to the electrical equipment configuration, but refers to the vacuum pump. Vacuum pump is the core component of vacuum packaging machine, and its working efficiency directly determines the working efficiency of vacuum packaging machine, which is also the fundamental reason for the price difference among major manufacturers.
3. Ask other questions. The so-called additional questions are whether tax is included, whether freight is included, what accessories are given at random, what wearing parts and consumables the machine has, and so on. Buying equipment is a one-time investment, but buying consumables is a long-term thing, which should be paid great attention to.
