Cable type changeover without production downtimes - SAMP presents Chameleon
Super Flexibility without Production Stop
In the constant effort to provide cost-effective solutions and innovations to the cable industry, SAMP continuously invests in Research & Development. The latest and most important innovation is the Chameleon technology, a breakthrough solution for cable type changeover without production stop and without speed limitations.
Just like a chameleon has the ability to change colour fast and frequently, the brand new solution guarantees maximum flexibility, efficiency and reliability throughout the extrusion process.
Traditionally, when changing a cable type, for instance when going from a striped cable to a non-striped one, the procedure to be followed is rather long and includes a number of steps:
1. Stop the production line;
2. Cool down the machinery;
3. Open the extrusion head;
4. Replace the distributor or ring that creates the stripe on the cable with a similar device allowing the application of a single layer without stripe;
5. Reheat the machinery;
6. Start again the production.
This rough outline describes what takes place in the majority of the cases. We have intentionally avoided to mention any other unconventional, home-made attempt to avoid production stop, since these cannot guarantee product homogeneity and therefore do not meet the market requirements, especially in those demanding fields such as automotive.
Needless to say, the process described above leads to a production slowdown and delays can even amount to several hours in case of CV lines.
In order to maximize efficiency and eliminate non-productive time, SAMP has recently developed Chameleon, a revolutionary solution that allows the cable type changeover from a striped cable to a non-striped one, and vice
versa, in just a few seconds, without stopping the production line and disassembling the extrusion head.
to control the final melt flow directions.
The Chameleon technology allows the production of perfectly homogeneous cables, since all the insulation materials are obtained by working at the same temperature and the same pressure level. Moreover, the same distributor is used when
producing striped and non-striped cables, so that no extra device is needed for the changeover.
The Chameleon technology is suitable for all SAMP extrusion heads, including the more sophisticated like the TX6V, which is equipped with the “0-scrap” quick change colour system for the cable stripe, and the TX6V2, where the
“0-scrap” system can be applied both to the stripe and the insulation. All parameters can be easily managed via the
SAMP Supervision and Control Unit, through which production can be automatically programmed and a number of statistical and graphical analysis can be carried out.
