Try to make a trial, and then you will know clearly.

Changli is one professional manufacturer in stone cutting field for over 15 years.We 'd like to introduce who is using our products in your area for you check the quality.If not available,I think a small amount trial order for testing is necessary.

To charge the sample fee is also to proof that you indeed need them,and show
your honesty to us.

We would prefer you to put our company logo on the products. But if you insist
to put your own logo on the blades. We will also do it for you but need to
charge some money. Maybe 1-2% of the products cost.
4.MOQ
Any quantity order is available.
For first testing order,no limited on how much you put.
5. What we should do if your products can not run well?
Firstly, please check your installation, the working machines, and the working
conditions, whether all these are in a normal situation
Secondly, please check out whether the co-operation is in the right way. If it is
still not working, the reason is mainly in the products. In this case, please find
out the reason according to your experience and run it again.
If still can not solve the problem, please take is off from your machine, and
then give us detailed report. Our technician team will analyze the reason and
to find out the solve way for you.
