Why Can We Always Ensure Excellent Quality

Quality Control

Use tools such as dial gauge, micrometer, tachometer and tensiometer to measure and meet the configuration requirements.

After the equipment arrives at your site, we will send someone to open the case for inspection. Both parties will open the case and order the parts together. We are unconditionally responsible for the defective parts, and the supplementary parts should ensure the installation and debugging progress of your equipment. You have the right to reject the equipment with obvious defects inconsistent with the content of supply and require us to provide qualified equipment again within the specified time.
