Surface Treatment for Metal Injection Molding Robotic Components




The very common surface process for MIM (metal injection molding)

 rc helicopter drone parts is magnetic grinding. It is processed by magnetic grinding machine and needle, mixing brightening agent and water. Put products on grinding machine plate for grinding 20-40 minutes. The grinding time is subject to the requirements of brightness.


Another common surface finish for MIM robotic parts are sandblasting. It is processed by sandblasting machine.
There are two kinds sandblasting machines: automatic and manual. Adhering required sands to product surface by Pneumatic nozzle. The pressure is usually 3 kg, keeping for 10 minutes .At same time it can chose fine or rough sands according to different requirements.
