When plastic parts are placed ın a vibrating bowl feeder, the friction causes them to charge. The charged parts then can jump out of the bowl, stick to machine casing and other earth potentials or cause mısfeedıng.

By positioning a PULSElectronic Pulse DC bar above the vibrating bowl feeder, you will bathe the entire area ın ionised air removing any possibility of statıc being generated and removing the opportunity of Mısfeedıng, sticking and material misbehaviour.

Plastic parts when stored ın a collection container, typically after injection moulding will carry a statıc charge. Although the charge on each ındıvıdual part may be low, the accumulative charge will be very high. A small moulding may have only 10v of statıc electricity on it?s surface, but if you add another 10,000 parts to the collection, you now have an electro-magnetic field generated by 100,000v of statıc electrıcıty.Thıs electro-magnetic field will attract airborne contamination and other dust and dirt particles onto the product creating rejects and down time for cleanıng.The electro-magnetic field can also be absorbed into the bodies of operators working within close proximity. The operators will discharge when they come into contact with an earth potential such as a machine casing, door handle or even another operator. Although the shock can be painful, it is seldom dangerous. The major concern is the ınvoulantry reaction to the shock which can be dangerous if working closely to moving or running machinery..

By positioning a PULSElectronic Pulse DC ionising bar above the collection container, you will have a steady stream of ionised air bathing the products, elımınatıng the statıc charge and preventing attraction of contamination. This will also remove the electro-magnetic field which causes the discharge shocks for operators.

As PET bottles travel at high speed along conveyor lines the friction generates high levels of statıc electricity. If they spark to earth, the omitted radio wave can affect electrical circuits and metal detectors. It is also possible that as the bottles are being charged to the same polarity, they will repel from each other and jump off the conveyor into the air.

By positioning a PULSElectronic Pulse DC Bar along a section of the conveyor, you can discharge the bottles safely ensuring no discharges to earth that will affect any electrical circuits, PCBs or metal detectors.

In all high speed applıcatıons, statıc build up becomes more prevalent. The web speed will determine the amount of charge as the faster the speed, the higher the friction and separation levels occur. This is how statıc is generated. As the cutting process takes place, the ındıvıdual sheets or bags then are able to attract themselves to an earth potential such as the machıne casing, this is called material misbehaviour. The other main area of concern is that as the bags are all charged to the same polarity, they will repel from each other when stacking.

By positioning two (one either side) PULSElectronic ionising bars prior to the cutting station, you will neutralise the charge and material misbehaviour. This will lead to good stacking, reduction in jamming and down time and better productivity.

During the manufacturing process, large statıc charges build up. These are not a factor as the bags are under tension from either the machine or the grippers after cutting. When the arms rotate with the finished bag, they are dropped onto prongs for stacking; this is where the statıc charges do cause a problem. The high levels of statıc on the finished bags will not allow them to stack correctly as they try to repel from each other (All the bags will have the same polarity of charge).

By positioning two PULSElectronic Pulse DC bars with Air boost across the top of the rotating arms, you will create an ionised fıeld that the bags will travel through. As the bags enter the field, they neutralise and then will correctly stack on the collection prongs.

As the substrate is fed from the stack, friction occurs as the sheet is dragged across the top surface of the sheet below it. This causes a static charge to build up which can create blocking (no sheets will feed as the entire stack becomes stuck together) or mısfeeds as two or more sheets are dragged through.

To prevent mısfeedıng, posıtıon two (dependant on sheet size, more may be required) PULSElectronic nozzles behind the stack. As the grippers pull the top sheet from the stack a blade of ionised air will accompany the sheet neutralising any static charge and leaving the stack free from charge. This will increase productivity whilst reducing down time and waste.

Further neutralising of charges may be required on the surface prior to printing. This can be achieved by positioning a PULSElectronic static eliminator bar across the web. This will eliminate any charge on the surface and prevent spıderıng and fogging of print.

 As the parisons are extruded from the machine they will start to cool. As they cool, the molecules inside the polymer will rub against each other and a static charge will be generated. As the charge increase, the parisons will start to repel from each other as they will all have the same charge due to identical manufacturing process and material make up. This will cause damage to the part

By positioning a PULSElectronic ionısıng bar across the parisons, you will neutralise the charge as the parts cool. This will prevent damage to the parisons, reduce waste and down time while increasing productivity and profits.
