The materials of these parts are brass. For the gear, we do heat treatment to increase the hardness. For other joints and nuts, we make glavanization on surface. As the pictures show, glavanization can appear differents colors but all in high quality. If customer requires other appearance or other size, all can we do. For the equipement, we have one gantry machining center and three vertical machining centers to insure the yield.
