TLD QC Instruction:

We have implemented the following procedures in order to ensure all products meet our customers' high standards:
1) All raw materials and accessories must be checked or tested before entering production facilities. All unqualified materials are immediately rejected
2) We provide quality control testing and analysis for each product line
a) Workers manufacture products in accordance with provided technical documents. The first several     products of each day will be checked first by the worker, then by our full time QC inspectors. Mass production will begin only if the products have been tested and have passed inspection

4) Quality feedback from the marketing department is rapidly and efficiently delivered to the QC and technical departments, allowing design improvements and corrections to happen as quickly as possible
