Elion: perfect fuel transfer for the production in cleanrooms

Netstal machine equipped with a number of peculiarities that make them suitable for clean rooms:

• Drive cooled by water (to prevent the flow of necessary air cooling by air).
• Mold with a special coating plates.
• Highest amount of the machine for easy cleaning.
• Use of non-toxic and approved by the FDA lubricating oil.

The high technical level required of these machines has implications, as it is natural, in its design and manufacturing, and Netstal responds to the needs of this market with a special range of machines. For its manufacture, Netstal has created a separate area intended exclusively for the cleanrooms in specialized personnel riding only machines for medical applications. Employees are aware that this measure must meet standards and follow procedures special when working with these machines.

When you start the production of the machine, set in motion a procedure for preparing all necessary documents and to ensure that they are completed at the same time as the machine. Obviously, they are also measured and documented all the relevant process parameters such as temperature, pressure, tours, etc. The content of the documentation was drawn up jointly with a BPF (good manufacturing practices) Institute, which was a great help during the realization of the validation process.

Netstal machine software also meets the most demanding conditions:

• The use of passwords to identify the user protects the system from unauthorized access and guarantees the traceability of the interventions.
• The journal records all production processes.
• With the monitoring of the process, you can define tolerance limits for control systems of separation of rejected pieces.

In addition a Fat (Factory Acceptance Test) or a Sat (Site Acceptance Test) may be done at the request of the client. Such tests may include a visual inspection of the machine and in the review of the documentation or proof of operation with a mold of the client.

For this reason, Elion machines with closing forces ranging from 500 to the 1,750 kN are very suitable for the production in cleanrooms.

Then the company presents three points which demonstrate:

Emissions: measurements taken in the 100,000 class cleanroom have shown that it manages to reduce particulate emissions by 25 percent compared to the hydraulic machines of identical technical specifications. The design of the closure of the mold and the channels are largely responsible for this decline.

Mold closing incorporates a closed lubrication circuit and presents a clear and defined, provision of channels appropriate to the needs of users and the clean rooms.

The enclosed water cooled engine and the linear Guide of the mobile portamolde plate, ensure that the columns that serve as longitudinal braces of the closure of mold, do not require lubrication. In this way, provided the cleaning and maintenance.

Stainless steel covers are included in the standard version.

Thermal radiation, water consumption: double circuit cooling with heat exchanger of heat, the servo motors and servomotors converters ensure that the temperature is maintained constant in any machine.

Thermal radiation is considerably lower compared to the hydraulic machines due to the package of the engines cooled by water, the reduced values of thermal of the machine (which can dispense with moderate hydraulic tank) and that the drive is not continuous, but that it acts only when necessary. As a result, the consumption of cooling water from an Elion is approximately ten times lower than that of a hydraulic machine. The use of hydraulic oil and lubricant approved by the FDA, whose cost is very high, is also reduced in equal measure.

The design of the gears and the guidance of the movable components on linear bearings require a freezing power reduced compared to the drives of hu-sillo, even at very high effective forces or velocities. Thus reducing the thermal radiation of the machine and helps to keep the repeatability high over a prolonged period of time.

Power consumption: taking into account all aspects relating to energy consumption in production in cleanrooms, thanks to the reduced values of emission of the machine and also reduced dissipation of energy of the drivesthe potential savings is considerable. Compared to the hydraulic series SynErgy, total energy consumption is reduced by half. With this energy can be used both small systems of air conditioning as filter systems to maintain the quality of the air.

Clear advantages in the use of the fully electric Elion series in clean rooms. The costs of operation in up to 20 percent can be reduced depending on the size. Costs of investment and operation of systems of cooling and filters are also reduced because the values of the emissions are very favourable. Elion series drives are designed to ensure a long service life and successfully meet the requirements of repeatability in applications in clean rooms, facilitating in particular the annual recalificaciones of the machines. Noise pollution is minimal without to poor values of injection or dosage. In addition, the Elion sets precedents in the constancy of the processes and the quality of the castings produced.

In addition to all these technical aspects on the machines, Netstal offers clients a programme of technical advice on the manufacturing in cleanrooms and facilitates contact with their partners.
