Wire Drawing Machines

We design and manufacture wire drawing machines that process wires of various metal types and sizes from thick to ultra-fine.

IC Bonding Wire Manufacturing Machines

IC bonding wires, especially ultra-fine metal wires, play a crucial role in various industries today, by electrically connecting electrodes between semi-conductor chips and lead frames.

Rolling Mills

Saikawa has produced over 300 rolling mills for both domestic and overseas customers since 1992, when it completed the installment of a tandem line for FFC. Saikawa has expanded the rolling mill wire application to bare copper, stainless and metals over the years.

Wire Twisting Machines

Optical Fiber Cable Manufacturing Machines

In 1971, the former Yoshida Industries started the development of an optical fiber cable machine to provide technical support to Nippon Telegraph and Telephone Public Corporation, today known as Nippon Telegraph and Telephone Corporation (NTT). Later, Saikawa took over the project from the former Yoshida Industries and since then has continued development by applying its proven technology and know-how to introducing new products.

Optical Fiber Cable Core Manufacturing Machines

Wire Drawing Machine
As the machine draws a cable core φ125μm, it double coats the cable.

Screening Unit
Screening pressure is auto adjusted in response to the speed.

Coloring Unit
Even coloring is ensured during operation at high-speed.

Winding Units
Smooth high-speed wire winding is ensured. Wire is unharmed even when unexpected machine stoppage occurs.

Wire Twisting Machines

Drum Twister Type
A spooling drum rotates at high speed.

Cage Type
Consistent twisting is ensured because of a rotatable drive cage.

LAN Electric Cable Manufacturing Machines

Machines for metal telecommunication wires. Yoshida especially excelled in the production of machines for 4 as well as 2 strands twisting and acquired a number of technical patents over the years. Saikawa inherited a rich know-how from Yoshida and we expanded on the acquired technical resources. Saikawa continues to improve our technology to better meet the increasing needs for LAN cables and electric wires used for high-speed transactions at higher frequencies.

2 Strands Twisting Machines

Wire Pay-Off Unit
Two types are available: Fixed and 100% back-twist (dancer equipped).

Supporting Haul-Off Unit
Twist tension is controlled by registered wire data.

Spooling Unit
Electricity consumption and noise reduction are realized by the use of double twist.

Operation Control Panel
Easy to operate and maintain via the touch panel display.

Wire Stranding Machines

Core Pay-Off Unit
Core and inclusion are supplied. The cross-shaped spacer compensates for wire twisting.

Pay-Off Unit with Twist-back function
Vertical and horizontal types are available with pay-off tension controlled by the dancer embedded inside.

Binding Unit
Both center and side types are available with consistent binding tension.

Taping Wrapping Unit
Both center and side types are available with consistent binding tension.

Haul-Off Unit
Cable is protected from crushes and scratches because of double wheel capstan.

Spooling Unit
Single twist type. Bobbin traverse with both bobbin ends supported.

Operation Control Panel
Easy to operate and maintain via the touch panel display.

Ultra-Fine Wire Manufacturing Machines

As information technology advances, the demand for more compact cable manufacturing equipment is increasing in addition to the increase in frequency associated with high-speed processing through digitization. Demand for extra-fine coaxial cable (mini-coaxial) is growing, with applications such as notebook PCs, digital video devices, mobile phones, and in the medical field. Saikawa will take Yoshida Industries’ technology and apply our ingenuity to continue to increase productivity and improve quality.
