Seal systems - Import export

Rodless linear drives allow stroke lengths of up to 6000 mm with a reduced overall length. Stable guidance and durable sealing system even at high speeds and temperatures.

Tecnimodern's slanted or vertical form fill and seal machines with very low loading height allow the production of polyethylene or polypropylene film bags from a flat film roll. The film can be neutral or coloured, with continuous printing or centred with print mark. These TEC30 packaging machines have the advantage that they can be equipped with either a thermal sealing system for heat-sealed films or an impulse sealing system for polyethylene films, depending on requirements. To meet the need for all types of packaging, feeding and product shapes, we offer various automatic feeding systems, such as: - Counting with vibrating or centrifugal trays - Weighing with linear scales - Dosing by augers or volumetric feeders

A single-acting rod seal, Zurcon® L-Cup® is an alternative to the U-Cup. It is a highly effective sealing system offering optimized sealing performance and extended service life. With exceptionally low friction properties, it has high wear resistance, back pumping ability along with high static and dynamic tightness.

In heavy duty applications, leak free performance and high service life cannot be assured by a single sealing element; therefore, specially developed ”system seals” are arranged in series, building a ”tandem configuration”. Each sealing element in a system has its specific function and their interaction needs to be secured to get a redundant sealing system. The primary seal in Zurcon® material has an excellent wear and extrusion resistance under extreme working conditions. It allows a fine lubrication film passing this first barrier, ensuring the necessary lubrication of the secondary sealing element for long service life. The ”tandem arrangement” requires an outstanding back-pumping ability of the primary seal and the secondary seal, if a double acting scraper is installed.
