2: Workmanship of vacuum machines, especially vacuum chambers. For example, whether the workmanship of the plexiglass cover and the vacuum chamber is smooth without solder joints.

3: The size of the vacuum pump. Generally, the vacuum machine has a size 20 pump and a size 40 pump, so there will be a big difference in price.

4: The quality of vacuum machines is currently almost the same in the market, mainly for services, so when you buy equipment, although you buy things, you still have to have a better relationship with the sales staff, so that people will be more willing to do things for you in the future.

5: Whether the equipment manufacturer is suitable. Try to find a medium-sized company. Large companies will not pay attention to your small customers. Small companies cannot meet the requirements, so choose a medium-sized company.

6: Price issues. Don’t pay the highest price. The company ’s own hard-earned money ca n’t stand the frustration, nor can it be the cheapest. It must be fussy, and the middle price can be. One point and one point really make sense.

7: The device is the same as the mobile phone. Take care of it a little, keep it light and dry, keep it clean and dry, and it can be used it for 5-10 years without any problem.
