First to answer this question, let’s figure out the reasons of an used glass tempering lunch to market.

1, Level A, new machine, and good running. The owner decide not to running this glass factory for different reasons.

2, Level B, kind of new machine, but not good-running. The owner find the machine is not good running, such as not good tempered glass quality, and can’t be debugged qualified in any chance;

3, Level C, old machine, fine running. The owner sold the machine because they have to update, but not enough space to put the second one.

4, Level D, old machine, not good-running. The owner sold this one, because it has zero value to them.

So you can see the most reliable machine is Level A machine, but not easy to catch this chance.

For level B,C,D, It could say not reliable. 

Old means all parts are old and in the same time aged-designed. 

And not good running means you need to spend a lot effort to change it to a good running machine, or will never success.

Meanwhile, the dis-assemble and re-assemble of the used glass tempering furnace is also very important. The precision of mechanical system will sure get hurt more or less. And the wiring of an used machine is always a mess, that will bring you trouble when maintenance.
