1. Aluminum alloy material is not easily deformed and has better fixation
2. POM material fixed ball reduces the virtual position of the arm needle, making the arm swing more stable
Made with a quality light weight high tensile strength aluminum 6061 T6 to reduce gap and more stable to use.
Inserted with POM for better strength with flexibility to minimize the gap of the hinge pins in order for the arms to be more stable when in motion.
