Inspect every production

Well-trained and qualified employees are very important. Most of Junnuo's workers are experts with more than 10 years of experience in producing HDPE and PVC pipes and fittings in China. Their expertise greatly helps us identify major manufacturing defects in the manufacturing process, so as to avoid unqualified products on the market in a timely manner.

Dimensional testing and visual testing will be performed throughout the production process and packaging. If any manufacturing defects occur, they can be found. Prefabricated samples from our Quality Assurance department are tested by laboratory technicians through:

(1) Surface finishment;

(2) the dimensional accuracy of the sample;

(3) Date of extrusion and injection molding machine.

Only when the best test results are achieved can the product be released for production. These tests are carried out at the beginning of each production series to ensure the perfect quality of the piping system.

The company has a professional testing laboratory with complete testing equipment and has passed the certification of the national testing agency. JUNNUO Product Testing:
