Static Control on Unwind and Rewind Rolls

As the roll diameter changes in unwind and rewind applications, the efficiency of a static bar will decrease as the static bar gets futher away from the roll.

The NEW Simco ROLL FOLLOWER , equipped with a high efficiency static control bar, is designed for permanent mounting to an unwind or rewind stand for continuous control of static electricity. Photo sensors included in the system detect changes in the outside diameter of the material roll and automatically move the static bar to maintain a predetermined distance to the surface of the roll, regardless of the web speed. When the roll is finished the static bar retracts to its resting position, away from the roll. The system PLC allows the operator to easily program the unit for either unwind or rewind functions. The result is maximum static neutralizing efficiency regardless of roll diameter throughout the entire unwind or rewind process.

Static Control for Injection Molding

Injection molded parts can have high static charges which attract airborne contamination, resulting in product rejects. Operators may also experience uncomfortable shocks when working next to the collection bin.

A SIMCO Phoenix Ionizing Blower provides ionization to quickly neutralize the molded parts. As a result, the parts do not attract airborne contaminant and remain clean and operator shocks are eliminated.

Static Control for Cleaning Thermoformed Trays

Thermoforming trays attract dirt and contamination resulting in rejects.

SIMCO’s Phoenix Static Control Blower installed directly above the delivery of the thermoformed trays offers improved product quality with the reduction of dust and dirt.

Static Control for Plastic Parts Cleaning

Plastic parts can have high static charges and attract dust and dirt, resulting in rejected parts.

SIMCO’s Phoenix Static Control Blower installed on a belt conveyor, directed at the plastic parts, will neutralize the static charges, prevent reattraction of contaminates and reduce rejects.

Electrostatic Charging on Chill Roll Edge on Cast Film Line

A SIMCO charging applicator at each edge of the roll applies a static charge to the extruded film as it contacts the chill roll. The static charge effectively prevents 'neck-in' of the film.

Static Control for Pneumatic Conveying Static Removal

Highly charged slitter trim materials cling to the sides of the cyclone of the trim collection system, forming a clog across the exit duct. The trim collection system must be shut down - affecting all operations producing slitter trim. The Conveyostat system controls static on trim materials prior to entering the cyclone. Once neutralized, the materials flow smoothly throughout the system, eliminating system shutdown.

Using an Electrostatic Charge on In Mold Labeling (IML)

Static charges can be used to pin a decorative decal tight against the inner mold surface during injection molding, a procedure which greatly improves finished product quality. A decal is placed by robot into the mold cavity. An electrostatic charge is applied simultaneously as label vacuum is turned off. The static charge pins the decal to the mold. The decal will not slip or change position in the mold.

Using an Electrostatic Charge for Roll-to-Roll Changeover

Chargemaster applies a temporary charge to the leading edge of the roll of film at rewind. The edge then adheres to the core without the use of tape or messy adhesives. Finished product quality is enhanced by elimination of creases in the roll of film caused by tape and glue on the core.

Using an Electrostatic Charge for Interleaving a protection layer

Chargemaster pins the protective sheet to the base material, holding it in position through the shearing and stacking processes. Chargemaster equipment supplies the electrostatic force to bond a protective layer of paper or film to cut sheets of metal, glass, wood, and other products. Chargemaster is also used to hold wood laminates to core board prior to thermal bonding of desk tops and panels.

Static Control for High Speed Web

The NEW PerforMAX 3 Static Control System is capable of neutralizing charged materials traveling up to 2,500 feet per minute, and faster depending on conditions.

In addition, the PerforMAX works well in all types of applications and neutralizes even very high levels of static charges. It is particularly well suited for difficult applications, where a traditional static control bars may not be enough:

• Winders and rewinders, where the material is often far away from the static bar due to web path restrictions
• High speed webs — the PerforMAX can handle speeds up to 2500 feet per minute and more
• Over open webs where it is inconvenient to locate the static bar close to the web
• In applications where the operation of the static eliminator must be closely monitored

Static Control on Rollers

Particulate is attracted to a charged rubber roller causing impressions from the contaminant to be transferred to the paper. A Blue Bar installed facing the roller takes the charge off the roller.

Static Control on a Wicketer

Static charges can make bags stack poorly, decreasing production yields and increasing rejects. Because of its extended range and high ionization output, the Blue Bar can neutralize static on materials several inches away, eliminating the static charges responsible for stacking problems on the wicketer.

Electrostatic Charging for Bagmaking

The speed of the conveyor can cause the lead edge of the bag to lift up and shift. Electrostatically pinning trailing to leading edges prevents lifting and keeps bags proceeding smoothly along the conveyor line. Chargemaster can also be used to remove air from bags prior to packaging. The reduced thickness allows the use of smaller, more cost-efficient packaging.

Static Control and Air for Bottle Cleaning

SIMCO's ionizing air nozzles are ideal for delivering ionization into inaccessible trouble spots, such as isolated, hard-to-reach sections, dirty areas, or small spaces. Operating on compressed air, nozzles provide a highly efficient pin-point source of ionization to neutralize charges in very specific spots, often several inches away from the nozzle tip. At the same time, dust, dirt, and particulate are blown away from the targeted surface. Available in four styles, the nozzles can be arranged in many configurations to accommodate space limitations on industrial machinery. They are available individually or optionally mounted on a standard air bar header.

Static Control on an Open Web

Static charges on an open web can attract dirt, shock operators and cause product defects. A Blue Bar will neutralize the static charges, eliminating production problems. The Blue Bar neutralizes static charges on webs at speeds to 2500 fpm at 1" and can be mounted up to 6" from the web at slower speeds.
