How to choose a vacuum machine

When purchasing equipment, choose the model first, which device has a high cost-effectiveness compared to the size of the device you packaged yourself.

2. Whether the equipment output and vacuum machine strength meet the packaging requirements.

3. The workmanship requirements of the vacuum machine, especially the vacuum chamber. For example, whether the workmanship of the organic glass cover and vacuum chamber is smooth and the solder joints are smooth.

4. Vacuum pump issue, generally there are 20 pumps and 40 pumps in vacuum machines, so there will be a significant difference in price.

5. The quality market for vacuum machines is relatively small, mainly focused on service. So when buying equipment, although you are buying something, you still need to have a good relationship with the salesperson. In that way, in the future, people will be more willing to serve you.

6. Equipment manufacturers should try to find a medium-sized company. A big company won't pay attention to your small client, and a small company may not have the strength to do well, so choosing a waiting company is not wrong.

7. Regarding pricing, do not choose the company with the highest price. Your hard-earned money cannot withstand the hassle, and you cannot afford the cheapest. There must be some tricks involved. A moderate price is enough, and it makes sense to get what you pay for.

8. Like a mobile phone, devices should be taken care of and handled with care, keeping them clean and dry. They should be used for 3-5 years without any problems, and of course, vulnerable parts should not be included.
