Quality Control

Choosing SORL Bulgaria as a partner, you will get more than just the parts you ordered. Your business will benefit from the Quality Assurance process we follow and are so proud of.  

This process allows us to improve the overall production quality and make sure that we learn from our mistakes. Even though the parts pass numerous quality checks, if you have a claim, please don’t hesitate to send it back to us. Your feedback is important and useful for the R&D team. 

In addition to our internal processes, we also have an ISO 9001 certificate, in order to improve the quality and the services we provide. Having independent audits is our way to show we are committed to reaching the best possible quality.

SORL Production process

We are performing 3 inspections to prevent faulty products reaching our customers. The first check is being made by the factory before the goods shipped to Bulgaria, then again we check them before we store them in our warehouses and the third QC is before we ship them to you. Implementing this process in SORL Bulgaria gave us the opportunity to have specially trained quality controllers, who are responsible for the visual and performance checks of all goods that go trough our warehouses. 

Recently we have doubling the size of its previous operational laboratory. This new laboratory opening is in line with the company's strategy of increasing its operational capacity and providing its customers with constantly improved quality of products.Our state of the art laboratory will house our Quality Assurance Team and will be entirely focused on Quality Control of incoming products, to ensure customer satisfaction and reduce claims.
