Developed the world's first multi-core electrostatic shield drain wire processing machine for the automotive market
February 27, 2026
ShinMaywa Industries, Ltd. (Head Office: Takarazuka City, Hyogo Prefecture; Representative Director and President & CEO: Tatsuyuki Isogawa) has developed a new automatic wire processors, the Multi-core Electrostatic Shield Drain Wire Processing Machine "SS21," and will begin selling it from March 1, 2026.
The newly developed "SS21" is a processing machine that is the world's first *1 for multi-core electrostatic shielded wire, and is characterized by its ability to fully automate a series of processes including "length measurement," "cutting," "sheath (insulation) stripping," "processing heat shrinkable tube into drain wire," and "drain wire stripping."
If all of these steps are applied to both ends, the process can be completed in as little as 17 seconds.
- *1 Basis for claiming to be "world's first": Based on confirmation of previously reported information on automatic wire processors around the world and an understanding of the trends of competitors (limited to automatic processing of "multi-core cable" and "electrostatic shield drain wire").

Background of development
In recent years, the automotive market has seen demand for improved preventive safety performance, further electrification, and computerization, and as the number of sensors and electronic devices installed in each vehicle has been on the rise, the issue of increased noise inside the vehicle has arisen.As a result, there has been an increase in demand for multi-core electrostatic shielded wire, which has excellent noise resistance and can accurately transmit signals.
Previously, the "cutting and sheath stripping" steps in the processing of multi-core electrostatic shielded wires had been automated, but in order to meet the increasing demand in recent years, there was a desire to develop a new processing machine that would automate all subsequent processes.
In response to these demands, we developed this machine using our newly patented proprietary technology. This enables us to automate processes that have previously been difficult with multi-core cables, such as "straightening (unwinding) twisted core wires," "separating the drain wire from the core wire," and "automatic attachment of heat shrinkable tube and high-speed heat shrinkable processing." Furthermore, by combining this with our proprietary structure and conveying technology, we have succeeded in automating the entire process in one stop.
As a pioneer that marks 70 years since the start of its wire processing machine business this year, we will continue to contribute to improving our customers' productivity and quality by developing new technologies that meet market needs and providing comprehensive after-sales service.

1. Features of the multi-core electrostatic shield drain wire processing machine "SS21"
- 1 For a bundle of multi-core electrostatic shielded wires, a series of processes such as "length measurement," "cutting," "sheath stripping,"processing heat shrinkable tube into drain wire," "drain wire stripping," "drain wire cutting," and "discharge" can be performed fully automatically.
- 2High-precision machining is possible by adopting a station structure that allows detailed settings to be made in process units.
- 3By adopting a unique mechanism and various sensors, we have achieved high-precision processing of everything from drain wire sorting to heat shrinkable tube processing.
- 4 U-shaped transport allows continuous processing on both ends

[Reference] What is multi-core electrostatic shielded wire?
A cable that has noise resistance by bundling multiple electric core wires together and covering them with a metal shield.
The "electrostatic shield" made of metal foil serves to prevent electrostatic noise from entering from outside. The "drain wire" is placed in close contact with the shield and serves to dissipate electrostatic noise received by the shield to the ground.
