Polastorm has strict quality control system to ensure every propeller which received by our customer is qualified.
Quality consciousness is instilled from raw material processing to final packing. Quality inspection is carried out during Casting process, Machining Center, Painting and Packing for every propeller. We also have a series of analysis equipment to assist the inspection such as Coordinate Measuring Machine, Rubber Torque Tester, Hardness Tester and Dynamic Balance Machine.
At the meanwhile, we delegate our local government quality inspection department to inspect other propeller data such as composition, salt spray.
