Quality Control System
Quality is a kind of faith, and Puhui regards "product quality" as the life! As a quality-oriented company, from the procurement of quality raw materials to packaging until the delivery of products, strict quality inspections are carried out at each stage.Puhui has many years of experience in extrusion and injection molding and is the market leader and pioneer in the manufacture of HDPE and PVC piping systems in China. Our quality control systems include:
Testing and acceptance of raw materials
High performance raw materials are the basis for the production of high quality piping systems. Puhui generally uses Sinopec, Shanghai Petrochemical or Nordic TOP QUALITY raw materials to produce pipes and fittings. These materials have been identified as the best ingredients by professionals. The superior performance and stability of these materials establish a high reputation in the market for Puhui pipe fittings.
Inspect every production
Well-trained and qualified employees are very important. Most of Puhui’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. Puhui Product Testing:
