Quality cleaning for metal worked components

Metal-worked aluminium components are literally singled out for individual treatment by a new, aqueous based, three stage, wash rinse and dry system from Guyson International.

Metal worked aluminium components are literally singled out for individual treatment by a new, aqueous based, three stage, wash rinse and dry system recently designed by surface cleaning and finishing machinery specialists Guyson International Limited.

Suitable for a continuous flow of newly machined, drilled and tapped components in sizes up to 200mm wide by 200mm high, the Guyson Marr-Line 200/3 washes, rinses and dries each component individually, at a rate of up to 240 per hour, as it progresses through a sequence of three stainless steel process chambers.

Fitted along the full 4 metre length of the continuous stainless steel, twin chain, indexing conveyor is a series of cross jigs, dedicated to suit the individual shape, size and style of the component, to ensure that each one is correctly orientated and presented in an identical way throughout the complete three stage process.

This precise presentation maximises the effectiveness of every cleaning operation.

Dwell times and indexing times are variable and preselected.

A 15 second dwell time for each of the actual washing, rinsing and drying operations plus a 10 second indexing time to cover the duration of the movement between the stages provide a typical programme for an output of 240 components per hour.

As each component pauses inside the two washing and rinsing chambers, contamination such as oil, swarf and shop dirt is promptly removed from all surfaces including the recesses of ports and drilled areas.

These are targeted to be saturated by a powerful high intensity heated spray delivered under pressure from a series of overhead and side positioned V-spray pattern jets.

Different specialised water based solutions are used for each operation, each one having its own independent filtration facilities for the recycled solution.

Both are fitted with a 200µm in-line unit with an extra fine 20µm filtration included for the rinse solution.

Additional compressed air blow off facilities positioned after both wash and rinse sections minimise carryover of excess solution which assists the drying operations carried out in the third and final chamber using blown heated air delivered through a-series of louvres positioned above and below the conveyor.

Wider, weightier and more heavily drilled components needing conveyor loadings up to 150kg and, where necessary, the use of pneumatically operated sealing heads equipped with up to 20 jets or more can also be singled out for this precise and intensive individual treatment.
