Components made by injection moulding are available in various materials including:
CMG is constantly developing new materials both independently and in partnership with our customers and suppliers – if we can source a material in powder form, we are willing to run trials.
The density and performance of MIM parts is comparable to those of wrought and cast components. As with CNC machining or casting, components made using the MIM process may contain some porosity, but this will be very fine and isolated. Generally after the sintering stage the surface finish is around 0.6-0.8 microns and the theoretical density of the components we produce will be controlled within the range of 95 - 98% dense. CMG technologies manufacture parts from micron powders, enabling us to produce parts with wall sections as thin as 0.5mm which are hermetic to greater than 10-10 torr for applications in Gas Analysis and Hermetic Packaging.
