Ultrasonics speed up cleaning of printer parts

Kerry Ultrasonics product story

The cleaning of inkjet printer components made by Marconi Data Systems has become faster and less labour-intensive with the introduction of an ultrasonic cleaner from Kerry.
The cleaning of inkjet printer components made by Marconi Data Systems has become faster and less labour-intensive with the introduction of an ultrasonic cleaner from Kerry.
The Microclean Compact 300 machine has significantly increased throughput for the company, which manufactures systems to apply barcodes, graphics and other data to a wide variety of packaging and printed materials.
Delicate print head components made of stainless steel and PEEK are now cleaned so thoroughly that they are ready for assembly in a clean room with no further finishing.
Marconi uses the Microclean Compact 300 both to finish new parts and to recondition used print heads.
Before the introduction of the Kerry unit, only a few small components could be cleaned at one time in a basic bench-top bath.
However, with the new higher capacity machine, a single operator can rapidly clean the components of several complete print heads at the same time.
With printer nozzle parts measuring only microns across, a consistently thorough cleaning action is essential to remove swarf, carbon deposits and, in the case of used components, toner residue.
*Polyetheretherketone, a thermoplastic resistant to harsh printing chemicals The four-stage process begins with cleaning in an aqueous solution of Micro 90 detergent, which has little or no environmental impact and no ozone depletion potential.
The cleaning stage is ultrasonically assisted by Kerry's Neptune high frequency generator.
This allows an optimum frequency of 70 kHz to be selected, ensuring thorough soil removal without damaging the delicate stainless steel foils of the print heads.
Following the cleaning stage, components are rinsed first in tap water and then in deionised water, before being dried in hot air.
The parts making up each complete print head are then sealed in airtight bags and taken directly to the clean room where they are assembled.
Ends.
