The customers are concerned about the fineness?

Our factory has a professional test plant for customers to test the machine free of charge. Third-party testing of fineness is available to the customers who can see the real effect of the machine, to avoid the false propaganda and promises of some manufacturers. In order to avoid a trip in vain, the customers can send the materials to our plant for testing. If they are satisfied with the fineness, they can bring the materials to our plant to test the machine. Let the machine speak for itself.
