working method of GRISOTUB PS

The filled tubes are placed in the multiple tube holder and they are pushed between the sealing bars. We suggest you to work at least with two multiple tube holders. The sealing cycle is actuated by the bi-manual switch. When the cycle is completed the sealed tubes are immediately released. The welding parameters (sealing time, cooling time, pressure, heating temperature) are quickly and accurately set and saved by way of a touch panel. Height adjustment of the sealing bars accommodates tube lengths up to 260 mm.

We are also ready to undertake tests with your tubes. Please send us approx. 20 samples of your tubes.
