Casting For Drone Rotor Arms

This drone rotor support is made of die-cast aluminum as substrate and is part of Sand Casting, which is manufactured by Dongguan Shengpeng Precision Technology Co., Ltd. The central circular base is equipped with positioning holes and passage holes for the installation of the rotary shaft and transmission torque; Support arms with fixed holes extend from all sides, which can directly fix motors or electronic speed controllers. Some armatures adopt empty design to reduce weight; The elongation structure of the column on the side is used for integrated electrical adjustment or wiring, and the overall structure is ensured by pressure molding technology.

Step 1: In the machining process, we first obtain die cast aluminum blanks through Customized Sand Casting Service, ensuring that complex spokes and mounting seat contours are formed in one go, greatly reducing subsequent machining allowances.

Step 2: Transfer the raw material for the precision milling to the CNC machining center. First, the casting is effectively removed by the crude milling machine, then the high-precision forming is carried out on the mounting surface, the housing holes and the positioning spindle holes are carried out using high-speed precision milling machines. The equality and position tolerance of key hole positions are strictly controlled at ± 0.01 mm to ensure accurate fixation of each component;

Step 3: the workpiece after milling is degraded; Perform natural anodizing to create a transparent protective layer of 8-12 microns thick aluminum oxide.

As a professional manufacturer of CNC processing services, Dongguan Shengpeng Precision Technology Co., Ltd. We offer simultaneous services from Sand Casting Plant to precision CNC processing. We support a comprehensive adaptation, whether it is dimensional adjustment, material exchange or modification of the surface treatment process, everything can be made on request to meet your individual needs in different industrial scenarios.
