Static Elimination in Plastics Processing

TAKK static eliminators ensure a uniform spread of ionized air during slitting, sheeting, unwinding, rewinding, laminating, and coating processes. By doing so, they prevent static electricity issues, such as frequent personnel shocks, as well as problems like jamming, clinging, and sticking of materials during processing. These issues are commonly encountered with the papers and films used in converting and packaging.

Bag Wicket

Excessive static charges can make bags stick together or push apart in a stacked arrangement. This leads to inefficient stacking, lowering production output, and increasing rejects. To address this issue, installing static eliminators at the entry point, on the wickets, and at the stack ensures that individual bags and the stacked arrangement are fully neutralized, allowing for proper stacking.

Slitting

While unwinding, pulling the web from the roll creates a static charge that intensifies when the material separates, moves across rollers, and gets slit. This static charge can make layers repel each other during rewinding, leading to lower roll quality.

To prevent contamination and ensure high-quality rolls, install a static eliminator before rewinding to neutralize the charge.

Sheeting

In fast processes like sheeting, speed, friction, and separation create static. During sheeting, individual sheets are drawn to the machine and repel each other during stacking.

To improve stacking, reduce jams and downtime, and boost productivity, install a static eliminator above and immediately after the sheeting operation to neutralize the static charge.

Winding

During the winding operation, as the web is pulled from the roll and the material separates a static charge is created. This static attracts airborne dust and contaminates causing rejects, waste, and operator shocks.

On both unwind and rewind applications, installing a static eliminator on top of the roll will neutralize the charge and prevent contamination and shock.

Blow Molding

When the plastic parison comes out of the die and enters the open mold, strong static charges make it stick to the grounded metal mold. With multiple die heads, the parisons repel each other, leading to poor product quality and more rejects

To prevent quality issues, install a static eliminator as the plastic is extruded and enters the mold to neutralize the charge.

Film Extrusion

Static charges accumulate as the blown film cools and moves across rollers towards the wind-up, attracting dust and contaminants and causing shocks to operators.

To prevent slowdowns rejects, and operator shocks, as well as to enhance product quality, it is advisable to install static eliminators at the extrusion point and during the winding operation to neutralize the charge.

Injection Molding

At the end of the injection molding process, static is generated as parts drop into a collection container. Although the charge on each part is small, it accumulates into a significant static field as more parts gather in the collection area. This leads to the attraction of dust and contaminants, causing parts to become dirty, and operators may experience shocks.

To address this issue, install a static eliminator at the collection bin to eliminate these charges and prevent contamination.

Injection Molding (small, lightweight, complex parts)

During the injection molding of delicate and lightweight parts for medical, pharmaceutical, and other industries, the parts can stick to the mold ejectors or the injection mold face when the mold is open. Ideally, the parts should easily fall from the mold ejectors onto a conveyor or into a catch bin. However, if static electricity is too high and not controlled, the parts won't fall freely. This can lead to problems such as loss of usable parts, clogged ejectors, potential damage, downtime, reduced productivity, and profit loss.

To solve this issue, using a static eliminator bar with air assist flowing down the mold/mold ejectors' face will eliminate the static electricity and prevent these problems.
