A two-component dispenser shows its reliability in the dispensing of smallest quantities at SebaKMT

24.06.2020
In SebaKMT's production facility in Baunach, an eco-DUO dispenser from the micro dispensing specialist’s preeflow line, has ensured proper dispensing from the get-go. The first eco-DUO450 two-component dispensers and was officially sold and delivered in 2011 with the serial number 0001.

Precise dispensing of the high-performance silicone Wacker SilGel 612, protects components from corrosion: the Baunach plant manufactures, for example, noise loggers for acoustic zone monitoring of drinking water supplies and ground microphones for cable fault location in the medium-voltage network. SebaKMT is a member of the British Megger Group, a leading global supplier of measuring and testing equipment for the energy industry.

The noise logger from SebaKMT is a device for the acoustic monitoring of pipeline systems and is, for example, capable of transmitting measurement data via GSM directly to the control centre using a network mode. This enables a targeted search for leaks at those locations where there the highest probability of leakage exists. This effective pre-location method saves the drinking water supplier time and money.

The ground microphone is part of the digiPHONE+ NT set; an all-round tracking receiver. SebaKMT has combined two systems in one device: firstly, a ground microphone for locating flashover faults in underground cables and secondly, an earth fault locator for locating sheath faults in plastic-insulated PE and XLPE medium-voltage cables.

Both processes are implemented in a semi-automatic dispensing application. The following challenges are placed on the dispensing equipment: in order to achieve the required mixing ratios of the two casting components and repeatable results, dispensing must be carried out with high accuracy. In spite of frequent and longer production-related downtimes, the previously defined quantities must be applied repeatedly and accurately. The eco-DUO450 was impressive with its strong performance right from the start.

In all these years, it has only once been sent to the preeflow Service Center for a prophylactic check. There, during a longer downtime in SebaKMT production, it was cleaned and maintained, and the seals were replaced. After the two-component dispenser was returned, operations could continue as planned.

Petra Hofmann, Quality Officer at Seba Dynatronic Mess- und Ortungstechnik GmbH in Baunach, says of the two-component dispenser and the cooperation with preeflow: "We are very satisfied with the performance of the eco-DUO450. The system has been reliably meeting our requirements for many years with minimum maintenance".

Filling Composites in the Dental Industry

29.09.2020 -

In the dental industry, consumables such as composites are filled into disposable syringes with Luer Lock attachment or into smaller Unit Dose packages. These flowable filling materials made of plastic and glass are usually highly abrasive, highly viscous, and stringy. This places high demands on dosing and filling systems. The materials are used in the dental industry, for example, for sealing, restorations, or core build-up.
