What We Do

We carry out integrated production in-house of all manufacturing processes from procuring materials to packaging the final product.

At O.C.R., we primarily focus on the manufacturing of wire ropes made of stainless materials.
Our integrated in-house production system encompasses everything from wire drawing, to stranding, coating and terminal processing, which allows us to ensure quality control, and pursue manufacturing, research and development in line with customer needs.

Manufacturing Process

1Procurement of materials

We use carefully selected raw materials, primarily focusing on stainless materials (SUS304, SUS316L).

2Wire drawing

We use a diamond wire drawing die to thin out thick wire rods in stages. We are capable of manufacturing wires as thin as 0.009mm (9 μm) to 0.20 mm.

3Wire stranding

Using a seven-strand base configuration, we can strand stainless materials and other materials into a variety of configurations (tailored to customers specifications), from three strands up to 343 strands, according to the intended application. This is only made possible with the techniques passed on and improved upon over a 30-year period.
*Please contact us for more information concerning the use of other kinds of metals.

4Coating

－Coating

Polyamide resin (nylon 6, nylon 12) is extruded onto metal wires and fibers for molding and coating. O.C.R. is capable of resin coating at a thickness of 0.03 mm to 0.30 mm. We also provide color coating services upon request.
