Leverkusen / Győr, 16/03/2022 - Wuppermann Hungary Kft. (WH) now also supplies rounded and/or traverse-wound slit strip. The new traverse-winding-system was successfully commissioned at the beginning of 2022. The system is a downstream unit of the slitting line, which was already modernised at the end of 2021. With the modernisation, a new, state-of-the-art arrondising plant also went into operation.
Slit strip with rounded edges offers advantages in further processing as well as in the subsequent use of the end product. Rounded strips without burrs can be clamped more easily in tools. Surface treatment is more efficient. Surface treatment can be carried out more efficiently on rounded edges and coatings, such as paint, hold much better. From a safety point of view, burrs represent a risk of injury when handling the material in further processing steps and can lead to cuts during further processing. Rounded slit strips do not have this risk of injury - on the contrary: they protect against it.
From a technical point of view, the rounding off is a mechanical rounding of the cut edges, in which the zinc or zinc-magnesium coating is also pushed over the cut edges. In this way, the corrosion protection can be extended beyond the edges and the so-called cathodic edge protection can be strengthened or, in the case of thicker slit strips, brought about. Traverse-wound material ensures more throughput in further processing and significantly reduces set-up times, as more material can be wound onto one coil. Each traverse-wound coil increases productivity and enables longer continuous production. By requiring fewer coils to be reloaded, machine downtime and coil handling is minimised, and the required storage space and scrap generated are significantly reduced.
The conversion and expansion measure will be completed with the integration and commissioning of a fully automatic packaging in February 2022. In the future, the rounded and traverse-wound products will be galvanized inline directly in Hungary and further processed to the respective product, so that the logistical effort from production to the end customer will be significantly improved. This will save delivery routes and reduce CO2 emissions.
