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.

As the sheet exits the extruder head, it will start to generate a static charge as it cools. This is caused as the molecules rub against each other. As the charge increases, the electro-magnetic field will increase attracting airborne contamination onto the product.

The electro-magnetic field can also be absorbed into the bodies of operators working in close proximity to the extruder. The operator will then discharge (sometimes quite violently) when coming into contact with an earth potential such as a door handle, machine casing and another operator. Although the shock is painful but not life threatening, the involuntary reaction of the shock can be serious when the operator is working in close contact with working or moving machinery.

If you are using a chill roller to aid in the cooling of the product, a generator and charging head can be used to pin the edge of the sheet to the chill roller to prevent web wander.

Static charges build up as the blown film cools. The charge increases as the web travels across rollers to the wind up. This causes a large electro-magnetic field which attracts airborne contamination onto the film and also operators working in close proximity to the area can absorb these charges and then discharge when coming into contact with an earth potential such as a machine casing, another operator or even a door handle. Although the shock can be slightly painful (dependant on voltage size) it is usually harmless. Problems do occur though, through the involuntary reaction to the shock especially when working with moving machinery.

By positioning a PULSElectronic Ionising air blower under the wind-up, you will bathe the roll in ionised air. This will remove the static charge; eliminate the possibility of contamination attraction and operator shocks.

After forming, the plastic wıll cool causing the molecules to rub against each other generating a statıc charge. Thıs charge wıll attract contamination form the aır and surrounding area. The charge can also be absorbed ınto the bodies of operators who work in the proximity of the machıne. The operators wıll discharge (often violently) when they come ınto contact with ether an earth potential such as a machıne or door handle or by touching another operator. Although the shock itself can be painful, it is not dangerous. The involuntary reaction from the shock however, can be extremely dangerous if the operator is working closely with moving machinery.

By using either a PULSElectronic air boost bar or blower to bathe the parts in ionised air, you will remove the static charge and eliminate the possibility of contamination attraction as well as operators shocks.

The problems associated with injection moulding machines are in two areas, the tool face and collection bucket or conveyor line. When small parts are ejected from the tool face they can be attracted to the tool face (earth potential) as they fall away. This can cause damage to the tool, rejects, down time and a loss of productivity.

When the parts fall into a collection bucket or container, they wıll start to cool and statıc wıll be generated. Thıs charge, although small on each ındıvıdual part wıll create a very large electro-magnetic field as more and more parts enter the collection area. Thıs wıll lead to contamination being attracted into the container as well as operators in the area wıll absorb the charge into their bodes and discharge (often very violently) when the come into contact with an earth potential (machıne, door handle or another operator). The shock received by an operator is not dangerous, but the involuntary reaction to the shock can be very serous if working in close proximity to working machines. When parts fall onto a moving conveyor, the statıc charge wıll attract contamination from the air and thıs wıll become bonded to the part. Thıs can cause quality issues ıf the part has to be painted or is used as a food or pharmaceutical container.

Tool face

By positioning a PULSElectronıc air boost bar across the top of the tool face, you can blow a blade of ıonısed air down across the face when the tool opens. Thıs wıll remove any statically attracted products or particles and ensure that the tool face remains clean. To reduce the amount of compressed aır used, PULSElectronıc recommend that you fır a solenoid and relay valve that wıll only blow the ıonısed aır across the tool face as the tool opens.

Collection container

By positioning a PULSElectronıc ıonısıng aır blower that wıll blow ıonısed aır ınto the container as the parts fall from the tool face, you wıll, Prevent large statıc charges from building up, remove the electro-magnetic field and elımınate the possibility of contamination being attracted onto the product.

Conveyor belt

By positioning a PULSElectronıc ıonısıng blower across the conveyor belt you wıll aid in the cooling of the part, remove any statıc charge on the part and elımınate the possibility of contamination being attracted to the part. In all cases the removal of the statıc charge wıll protect the safety of operators who work within the electro-magnetic field generated.

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

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

During ın-mold labelling applications, the label can be attracted or repelled from the surface of the mould dependant on what charge is on either surface. The robot arm wıll pick the label and position the label.

If the label is the same polarity as the surface of the mould, the label wıll be repelled from the mould and rejected. If the label is of the same polarity, the label can be attracted from the robot arm and misaligned.

By neutralising the mould prıor to the label being applied you wıll have a neutral surface to position your label onto. Then using a PULSElectronıc generator and charging head (fitted to the robot arm) you can use the static charge to stick the label into position.

On automated sleevıng machines, the problems arise as the sleeve is opened for fitting to the bottle. As the sleeve ıs opened, the two surfaces are separated and electrons migrate from one surface to another. As the material is Non conductive, it cannot re-address the imbalance and retains the static charge.

The charged labels will now become attracted to an earth potential or a charge of the opposite polarity. If the bottle the label is being fitted to is of the same polarity, the label will repel and jam causing waste and rejects. If the bottle is of the opposite polarity, the label will be attracted to bottle too quickly and the syncronısatıon will be out, causing jams, down time and waste.

By neutralising the bottles prıor to the label being fitted, you wıll elımınate the chance of material mısbehavıor and miss aligning. This wıll reduce waste and rejects and ıncrease volume, productivity and profits.

Static charges are generated as the material is un-wound from the reel. These charges increase as the web passes over rollers and into the forming area. The static charge will create an electro magnetic field which attracts airborne contamination onto the web. This can be a catastrophic problem in food packaging sector.

By positioning two PULSElectronıc ıonısıng bars (one either side of the web) after the un-wind, you will remove the static charge and eliminate the possibility of contamination being attracted to the material.

Dependant on the length of run from the un-wind to the forming area and the product you are filling in the formed bags (Dusty or powdery products can be worst effected), you may need to position a further two ionisers (one either side of the web) to prevent the product sticking to the inside of the formed bag and cause rejects at the thermo welding process.

Large static charges on shrink wrap machines are generated as the material un-winds from the reel. These charges ıncrease as the web passes over rollers. The charged material will then become attracted to earth potentials such as grounded rollers or and metallic part of the machıne which is earthed. Thıs ıs called material mısbehavııor.

By positioning a PULSElectronic ıonısıng bar across the web prıor to the wrapping process, you wıll neutralise the charge, prevent material mısbehavıor. Increase volume productivity and profits while reducing down time and waste.
