Folding Machines

At the in-feed an electrostatic charge is created that will cause the top sheets to stick together. This usually results in a paper jam and consequently a machine stop. Blowing with ionising air nozzles will flutter the top sheets separating them and neutralising the static charge so that they can be removed from the stack individually.

Coating and laminating

Electrostatic surface charges are common in most coating and laminating operations where insulating (non-conductive) materials are processed at very high web speeds. The static charges cause a myriad of production problems.

Electrostatic Blocking

Magazines, pamphlets or books, coming from upstream machinery are conveyed on an automatic line to the wrapping or palletizing machine. Before arriving there, they are fed into a book collation machine to be stacked.

Tampon_printing_machine

Tampon Printing Machine

There are two principal problems caused by electrostatic charges. The tampon, a silicon based product, touches the product to be printed. Due to the deformation of the tampon, a static charges is created and fine paint splashes may be found on the product or on the tampon. An anti-static bar neutralises the tampon on its way to and from the printing block and will resolve this problem.

Roto_Gravure_zoom

Roto gravure printing

Rotogravure printing is specially developed for large, to very large graphic runs by using a rotogravure press. During the gravure printing process the printing cylinder rotates in the ink pan where the engraved cells fill with ink. As the cylinder rotates clear of the ink pan, any excess ink is removed by the doctor blade. Further around, the cylinder is brought into contact with the substrate, which is pressed against it by the rubber covered impression roller.

Manufacturers of packaging can experience multiple fires in their coating section caused by sparks from high static charges. Operators facing this issue turn to industrial antistatic solutions to help solving these static problems.

Bagmaking-machinery

Bagmaking Machinery

Bag making machines come in various configurations based on the type of bags produced by the machine. The bag making machine produces a bag by unwinding a roll of plastic film through a series of operations like (heat) sealing, cutting, slitting & stacking. Typical products are garbage bags, T-shirt bags, shopping bags and bags with a draw-tape.

Slitting-rewinding

Slitting and Rewinding

Slitting/Rewinding is a process to cut different type of jumbo roll’s with various material-width to narrower sizes at (very) high speed. This technique is suitable for several materials like paper, plastic film, flexible packaging, fabric or textile. The web is unwound and run through the slitter/rewinder, passing adjustable cutting knives, before being rewound on one or more shafts to form narrower rolls.

Bond Two Materials

Static charge between two surfaces can create enormous adhesion forces. These forces can also be used in a productive way in all kinds of production applications.

Feeder

Vibration bowl feeders

Vibration bowl feeders are designed to feed individual components/parts for assembly on industrial production lines. They are used when a randomly sorted bulk package of small components must be fed (in a particular direction) into another machine one-by-one. Vibration bowl feeders come in many shapes and sizes and can be used in the pharmaceutical, food, automotive, electronics and packaging industries.

Blow-molding

Blow Molding

A thin gauge of molten plastic, called a parison, exits the die head ofthe extruder and drops vertically between the sides of the open mold. The parison has a high static charge and tends to bow and attrack towards the grounded metal mold. This results in quality failures in the blown bottles. When using multiple die heads the parisons carry a static charge of the same polarity causing them to repel each other, which often results in rejected parts. Heat resistant anti static bars assure elimination of static charges and no production failures and machine stops caused by the negative effects of static electricity.

The process of In Mould Labeling (IML)

IML

In Mould Labelling, also referred to as ‘In Mold Labelling’ or IML, with the help of static electricity is becoming the new standard in injection moulding, thermoforming and blow moulding industry. Instead of conventional methods like decorating by printing directly or placing an adhesive label onto the product, the decoration is achieved with a pre-printed plastic label. The pre-printed label is positioned into the injection mould and kept in place by an electrostatic charge. This way the label will be moulded together with the product shape and comes out as a finished, fully recyclable product.
