Shaft (Direct bonding technology)
Material : Tungsten
Advantage: Separate different material part can be bond into one part without any additional material.
Remark: this technology leads us to manufacture more complicated design parts that are not possible to foam in single shot and different material combination. The above SEM image shows the strength verification result. It is confirmed the strength of bonding part is high enough since the breaking point is not at the joint section.

|Frame part (Eyewear)
|± 0.5% or less
|about 30 mm (max length)
Advantage: With free-form surface, it is not suitable for serial production by CNC machining. We accept secondary process (mirror polishing).
|around 5 mm.
Advantage: Cost reduction by changing manufacturing method from machining to MIM
Characteristic: Hollow structure (inside), thin wall thickness
Remark: It is a pipe-shaped component to separate 2 flow channels with the complicated shape and with outer projection and internal step.
|4.8 mm x 4.5 mm x 12 mm

Material: 17-4PH/SS 630 Tolerance: +/- 0.02 mm Weight: 0.8 g Size: 4.6 * 4.0 * 15.0 mm
This nozzle is an OEM part and has an internal hollow structure shape which requires the sharp edge in exterior design, and complicated step design in interior design. In case of machining production, it is required to chuck a position change several times to complete the internal flow structure forming. Our micro metal injection moulding technology will realise small complicated design nozzle serial production without any post machining process, thus not only the tight tolerance requirement but the positional accuracy will be satisfied. From this part, the smallest hole diameter is 0.7 mm and the tightest tolerance requirement is ±0.02 mm. At the inlet side, there are external thread lines for assembly, and these lines are formed in metal injection moulding process. In nozzle production, not only the external but also the internal structure tolerance is important to satisfy the nozzle specification.
