The testing includes over 20 key indicators such as purity, melt flow index, and tensile strength. Only raw materials that pass all these tests are allowed into the production process, preventing substandard materials from entering production at the source. In the production and processing stage, the company implements a 'total quality management' concept, providing systematic quality training to every production employee and clarifying the quality responsibilities of each position.

The pre-shipment inspection process is even more rigorous. The company has invested millions of yuan to build a professional product testing center, equipped with a series of advanced equipment such as pressure testing machines, corrosion testing machines, and wall thickness measuring instruments.Testing equipment. Each batch of finished products undergoes rigorous testing, including random sampling for pressure testing, corrosion resistance testing, wall thickness uniformity testing, and service life simulation testing. Only after all tests are passed and the test data is archived can the product be shipped out.
