Cleaning system cleans up fuel injection
parts
Multi-purpose system cleans and protects critical threads and shafts of several sizes of diesel injector components, which are all badly contaminated with grinding fluid and dust.
Cleaning of critical threads and shafts of several sizes of diesel injector components, all badly contaminated with grinding fluid and dust, has now been improved with the introduction of a machine manufactured by Guyson International High volumes of components are now thoroughly cleaned and treated with an oil based protective coating using a new four-stage conveyorised, washing, rinsing, drying and coating system

Keying surface produced for anodising
When Bodycote a world leader in metal technology, were faced with a demanding finishing problem, coupled with an extremely tight delivery deadline, they approached Guyson International for help.
The Guyson Marr-Line 300/4 is built to be compatible with both in-line and cellular manufacturing systems and has a totally enclosed conveyor path of almost five metres in length.
Shafts measuring up to 150mm long and 17mm in diameter, are placed lengthways, one at a time, across the width of the conveyor, onto nylon supports, either manually or by robot.
As they pass through the separate wash and rinse chambers the shafts are saturated by a powerful, high intensity spray from a series of overhead and side positioned V-spray jets.
Different concentrations of heated water based solutions, each pumped through an inline 200 micron washable filter element, are used for washing and rinsing.
Optimum wash-fluid life is catered for with a weir-type oil separator, processing all the used wash tank solutions and weirs off tramp oil for subsequent disposal.
Superfine 40-micron in-line filter between the pump and spray jets helps assure a cleaner solution for spraying.
To minimise carryover of excess solution, blown air at ambient temperature is delivered throughout the process by overhead airknives strategically positioned between each chamber.
Before entering the protective coating chamber all components pass through a drying tunnel where the air temperature is boosted to 80degC.
Inside the chamber an oil based protective coating is continuously gravity fed at ambient temperature on to the clean and dry surface of each shaft, through a series of small bore adjustable pipes into nozzles positioned around the component path.
This gentle delivery saturates and flow coats the entire surface area of each component and minimises the risk of vapours being caused by atomisation.
As the shafts exits the system, air knives deliver a curtain of air to flash dry the coated surface to maximises its corrosion inhibiting performance. Request a free brochure from Guyson International ...
