Guide wire manufacturing processes
update :
FUTA-Q has established a new production line in the clean environment in the second building of the Yagi Factory, located Nantan City in Kyoto. The line is to manufacture long-tapered wires used as a functional component such as a core wire of medical instruments including catheters or guide wires.
Into this dedicated line, we have introduced manufacturing facility such as a straightening machine, heat treatment furnace, centerless grinder, and self-made inspection device.
With these manufacturing equipment, multistage long-tapered wires with a cone shaped tapering point can be produced from a wire.
Processes such as jointing with a metal part or resin part, or coating are also available.
Long-tapered wire manufacturing processes
Please refer to the page indicated above on the processable size and precision.

Wire materials wound on a bobbin |

Bobbins stored on the shelves exclusive for wires. |
Straightening process |
 |
Curls on a wire caused by wound are removed through the straightening process in which the wire is pulled through several rollers. |
Heat treatment |
The heat treatment gives a wire stable characteristics and high quality, resulting in no deformations or distortions on it. |
|
Centerless grinding |
 |
The gap between the grinding stone and the regulating wheel is controlled by a computer program so that a wire with multistage tapers or a long taper can be obtained. |

The photos on the left show the wire surface samples after processed, captured with a scanning electron microscope (SEM). |
|
Measuring and inspection |
 |
The diameters of a wire, till its end point, are inspected using a high precision digital measurement tool. The straightness of a wire is checked through rolled on a surface table. |
