The raw materials have gone through multiple tests and the results show they are perfect for manufacturing high-quality twin screw extruder. In terms of their physical properties such as density and mass, we have conducted strict tests on them because these properties may change when subjected to certain variables such as heat which may influence the quality of the finished products. Regarding the chemical properties, we have hired highly educated and experienced technicians to help detect them. Nanjing Tengda Machinery Co., Ltd. does our utmost to ensure the raw materials conform to the standards.
