Product Introduction

This is a component of UAV(Unmanned Aerial Vehicle), made from Metal Injection Molding (MIM) process 420 stainless steel. And the component only did grinding surface treatment with natural color. We can see that the component have a very complicated shape. And the component also have good wear resistance and corrosion resistance.

With the continuous improvement of automation and reliability of UAV, UAV has the conditions of miniaturization, intelligence and low cost, and the civil application of UAV is expanding rapidly. In addition to the widespread popularity of consumer UAV, industrial UAV has developed rapidly in the fields of weather modification, emergency industry, meteorological monitoring, inspection, security monitoring, agriculture and forestry plant protection, surveying and mapping and geographic information. The demand for the UAV components with precision, high strength and complex shape is also increasing and the Metal Injection Molding (MIM) process can well meet these requirements.

Here are the advantages of Metal Injection Molding(MIM):


Less material waste

Lower overall product cost

Excellent mechanical properties

High complexity shape capability

Tailored solutions using unique materials

More efficient use of material and processes

Materials can be brazed/joined to a variety of components for complete assembly solutions.

Metal injection molding (MIM) offers a manufacturing capability for producing complex shapes in large quantities. The process utilizes fine metal powders (typically less than 20 micrometers) which are custom formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock which is granulated and then fed into a cavity (or multiple cavities) of a conventional injection molding machine. After the greencomponent is removed, most of the binder is extracted by thermal or solvent processing and the rest is removed as the component is sintered (solid-state diffused) in a controlled-atmosphere furnace.

The advantages of the metal injection molding process lie in its capability to produce mechanical properties nearly equivalent to wrought materials, while being a net-shape process technology with good dimensional tolerance control. Metal injection molded parts offer a nearly unlimited shape and geometric-feature capability, with high production rates possible through the use of multi-cavity tooling.
