Internal gear

Material : Stainless steel, titanium
Module : 0.09mm
Tolerance : Less than ±0.3%
Size: Diameter φ4mm / φ2mm
Weight : 1.17g / 0.08g

Our µ-MIM® (micro metal injection molding) technology enables flexible tooth surface and tooth shape without relying on cutting tools. As μ-MIM® components are manufactured using a mold, no tools are required and mass production with stable quality is possible. By using an X ray-CT, it is possible to convert internal 3D structures that are normally impossible to measure into data and evaluate them. In addition, by comparing the measurement results with 3D-CAD data, the required single pitch error and tooth trace information can be obtained immediately. Evaluating the graduation according to standards is also possible without destroying the measurement object to be measured.

Hinge

Material : Ti alloy, Ti-6Al-4V
Size : 4.7 mm x 1.2mm x 0.55mm.

µ-MIM® moulding production realises a side hole or any other additional hole design without any post-machining process. Therefore, it is not only possible to realise stable high-quality serial production of Ti or Ti alloy components but also to eliminate machining oil or metal chip contamination as no post-cleaning process is required.

Pinion gear

Material : SS630 / 17-4PH
Diameter : Ø2.95 mm
Module : 0.3 mm 
Tolerance : ±0.03 mm
Weight : 0.03 g
Ra : 0.43 µm

μ-MIM® technology realise stable serial production of small precise gears. Since we have good relationships to our mould tooling partners, the stable precide serial production is realised. The precise mould leads fine complicated designed gear stable production with low surface roughness and μ-MIM® feedstock will refrect the precide mould design perfectly. The surface roughness is Ra of 0.43 µm, thus the additional polishing process can be skipped.

Inside conductor

Material : Copper
Tolerance : ±0.01 mm

Special part for key cylinder

Material : SS316L
Size : 20 mm 
Tolerance : ±0.05 mm
Weight : 5.0 g

Advantage: Cost reduction by changing manufacturing method from machining to MIM.
Remark: In the de-binding stage of MIM process, the SP mould melts away with the temperature in the furnace, leaving only the metal component with hollow structure inside. This is a very effective method to create such hollow structure inside a metal component.
