Yobest has established strict pipe production standards to ensure product quality and quality, which is suitable for customers and products that pursue health and environmental protection.
1. Raw materials
All Yobest products are made of high-quality special materials certified by authoritative testing organizations to ensure product performance from the source.
2. Equipment
With high-quality raw materials, without high-quality equipment, it is impossible to make high-quality products. Therefore, the design of the screw and barrel has a great influence on its processing. Ubit adopts a three-section special screw suitable for PE raw material processing, which guarantees its plasticizing performance and its production efficiency. It is the excellent properties of the raw materials that maximize the performance in the finished product.
3. Process
Yobest converts granular raw materials into tubular finished products, which are completed through the processes of dehumidification, heating, pressure, traction and cooling, commonly known as processing technology. If the temperature is too high, the material is easy to degrade, and if the temperature is too low, there will be raw material. Therefore, the processing technology is also one of the key factors for the performance of the finished product.
Yobest adopts full computer control and online monitoring. As long as the process fluctuates, it will immediately alarm. The operator can troubleshoot or adjust the process in the first time, and reject unqualified products, ensuring product quality.

4.Detection
According to the performance verification indicators specified in the national standards, Ubit is equipped with a simple beam impact test, a hydrostatic testing machine, a melt mass flow rate meter, a differential scanning calorimeter (DSC), a circulating temperature control oven, and a refrigeration system. A full set of test equipment such as a test box, and a series of experimental devices such as a drop-weight impact tester, a tensile machine, an analytical balance, a desktop impact machine, and a Vicat softening instrument. Ensure the performance of the products produced. After testing by the National Chemical Building Materials Testing Center, National Chemical Building Materials Quality Supervision and Inspection Center, Shanghai Building Materials and Components Quality Supervision and Inspection Station and other testing institutions, the product quality fully meets the requirements of national standards.
