MHK specializes in some of the smallest wires in the world including the pictured ultrathin wire, which is 100µm in diameter.
Laser Cutting: Pipe
The pictured pipe has a 5.3mm O.D. cut in 0.1mm intervals. MHK has the ability to create pipes like this with a 0.7mm O.D. Materials include stainless steel and Ni-Ti.
Laser Cutting: Sheet Metal
Sheet metal can be processed in the same shape from 0.85mm O.D. to 5.3mm O.D. The pictured pipe segment has a 1.25mm O.D. Hole diameters are 0.11mm and 0.18mm.
Laser Cutting: Spiral-cut Hypotube
This nylon-coated hypotube can be processed with an O.D. of 1.19mm and an I.D. of 0.96mm. The slit width in the pictured example is 0.03mm.
MHK can weld 100µm wire and 150µm wire ropes (processing width: 0.2mm or more). With laser welding, we can process the tip of a coil into a smooth spherical shape. (Minimum outside diameter of coil 0.25mm diameter). Materials include noble metals, such as platinum.
Multi-wire, Multi-layer coiling
MHK excels in multi-wire, multi-layer coiling and has the ability to process both round wire and flat wire in two- and three-layer designs.
These coils are used, for example, in shafts of Endoscopic Ultrasound devices as described above.
Wire diameter range: 0.03-0.2mm
Coil size range: O.D. 0.4-3mm,
I.D. 0.2mm minimum
Length: 2.3m maximum
Flat wire can be rolled down to a thickness of 20µm minimum. It can also be processed down to a width to depth ratio of 1:5.
Precision brazing of a coil prepares the terminal of a wire for additional processing, for example, connection-processing.
Electrolytic polishing can eliminate the oxidized scale created by heat treatment.
