Strands: It can be so simple

CiS assembles stranded conductors using the most efficient and technologically appropriate process to the highest quality level. The customer benefits from reasonable prices with maximum availability and reliability.

Assembled strands are the simplest form of cable assembly: a multi-core stranded conductor is generally soldered to a contact or, if necessary, crimped using a seal connector or screwed into a screw terminal. Assembled strands are predominantly used in the automotive industry, in mechanical engineering and automatic system and control cabinet construction. They are frequently part of more complex structures such as multi-core cables or cable harnesses. This process is generally largely automated using semi- and fully-automatic systems.

The more expensive and time-consuming soldering process is generally used for small series and specific applications.

Semi-automatic systems are used for small and medium series. In this case, the strands are pre-cut and then manually inserted into the automatic system’s crimping tool. The crimping process, including crimp force monitoring, then takes place after automatic stripping. Additional tests are used to determine the quality of a crimp. These include crimp height measurement, tensile force testing, electrical tests, visual inspections and microsections.

Fully-automatic systems, which can perform cutting, trimming, tin plating, crimping, printing and testing functions on one or both sides, depending on the configuration, are used for medium and large series.

The demanding fine soldering process is generally used for specific requirements.
