New cleaning and static-neutralization device aims to improve injection molding workflow

Anti-static technologies specialist Fraser Anti-static Techniques (Devon, UK) has introduced an advanced product to clean and neutralize static in injection molding workflows.

Fraser’s Roto-Clean 4900 blasts pulsating ionized air from single or multiple heads to clean products and remove static electricity that could attract further dust. The device consists of a dual rotary nozzle driven by a patented centrifugal control integrated into a circular static eliminator.

Bruce Clothier, CEO at Fraser Anti-static Techniques, believes the unique device is the perfect complement to more traditional forms of cleaning and static control on the production line.

“Fraser has created a niche in cleaning and static elimination in injection molding environments,” said Clothier. “This includes our traditional range of 4125 air guns, 5100 and 5500 air knives, and 4510 and 4400 nozzles. We have now developed Roto-Clean to complement the capabilities of the range.”

Roto-Clean can work as a stand-alone head on a robotic arm, or as an array over a production line conveyor. It can clean complex shapes or bulky items and prevent further contamination, particularly where processes are heavily automated, said Clothier.

The combination of powerful, pulsating air and static elimination gives Roto-Clean an advantage over alternative products, according to the company.

The device uses less air that is delivered at a lower pressure than air knives. An air bar revolves at 60 revolutions per second using a patented centrifugal control powered solely by air. Air from two nozzles is ionized as it passes over a circular static eliminator. The pulsed airflow contacts the product up to 240 times per second, blasting away dust from various angles, including crevices. The nozzles require no additional power source.

Roto-Clean is available in diameters ranging from 112 to 178 mm with operational pressures from 1 to 3.5 bar.
