FACTORY CLEANING

Robotic hands clean, rinse and dry

The tendency of pressed parts to stick together pose a cleaning problem, making it hard to degrease, rinse and dry them.

Gateway Technology has developed a three-stage cleaning system under PC control with two-axis robotic handling to maximise parts throughput.

All three cleaning stages agitated immersion in cold solvent, vapour rinse and drying can be used at the same time.

Gateway’s thermal switch technology helps to cut emissions during loading and unloading by converting the vapour above the solvent into a chilled zone.

All solvents, including flameproof types, can be used in the equipment.

Ultrasonic cleaning has cut the use of solvents by 90% while maintaining cleaning standards at Lascara Electronics, maker of digital panel instruments.

Kerry Ultrasonics supplied the Microsolve ultrasonic cleaning machine, which is used to remove residual flux from printed circuit boards.

The integral two-stage system comprises a single ultrasonic cleaning stage, a solvent rinse and vapour drying with refrigerated cooling of the reflux.

Microsolve machines use the new HFE solvents from 3M which do not deplete ozone and have good cleaning properties.

A range of non-flammable, low toxicity solvents developed for electrical and electronic parts cleaning extends the E-Mec cleaning range from Solvitol.

The E-Mec 2 and E-Mec 3 solvents have a cleaning rating higher than 111-trichloroethane, are less aggressive than other solvents, are fast drying and leave no residue.

SOLVITOL

Smog-Eater portable industrial air cleaning equipment filters particles down to 0.01 m and is 99% efficient, the maker says.

Aluminium filtration units require only periodic cleaning and there are no cartridges to replace. Applications include filtering fumes or dust from welding, oil mist, PVC plasticisers, rubber and textiles.
