Guide wire manufacturing processes

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.

Straightening process

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

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.

Measuring and inspection

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.
