In order to provide qualified products for our customers, Jiangsu Xiandao will carry out quality inspection during the following steps:

1. Design control
Before the design of products, Jiangsu Xiandao will do sampling test as much as possible. The technicians will do scientific and reasonable design according to the combination of the specific requirements of the users and the practical results of the experiments. And we will provide sketch design of the processing flow of the equipment.

2. Purchasing control
Jiangsu Xiandao will conduct strict inspection, filing of the suppliers’ information and build the supplier database.

3. Manufacturing control
The manufacturing should be carried out on the base of the technical files. And the qualified products manufactured after each processing step must be marked. The mark of the key parts should be clear to ensure the traceability of the products.

4. Inspection control
(1) The inspection of the raw materials, purchased parts and outsourced parts should be carried out by qualified inspector. For large batch of products, sampling can be adopted. But the sampling rate should be no less than 30%. For key parts, precision purchased parts and outsourced parts, the inspection is necessary.

(2) The self-machined parts should be self-tested, mutual inspected and rechecked. The products passing all the inspections can be defined as a qualified product.

(3) The finished products can be assembled and started up in the factory. And the test running inspection should be carried out in the factory, then the qualified products can be delivered to our customers. The finished products which can not be assembled in the factory should be strictly tested at each production stages. And the assembly and debugging should be carried out in the factory of our customers, and to issue inspection certificate.
