2) The main body of the movement is made of aluminum alloy, which is manufactured by die-casting process and has reliable mechanical strength. Beautiful appearance, accurate size, good heat dissipation.
3) The movement is driven by parallel gear reduction connecting rods, which has high transmission efficiency and reduces power transmission. Low output loss; gear carbon steel material, carburizing heat treatment process, precision gear hobbing Work, anti-wear, anti-impact, the service life far exceeds the worm gear drive structure.
