A manufacturer of microwave amplifiers has installed a mono-solvent cleaning system from Kerry Ultrasonics to ensure its finishing process carries no risk to either its personnel or the environment
Installation of the new NDT line has also halved production time, allowing the firm to run just a single shift instead of the previous two.
The old NDT method relied on tanks that were four times larger than their Kerry counterparts.
Consequently, whereas one barrel of Britemoor 444 dye used to run out after a month, it now lasts three months.
"Aside from the significant savings we've made on dye, the reliability of Kerry's NDT system also guarantees a consistent level of finish that our manual process couldn't provide", explains Martin Brandist, the company Production Supervisor.
"It is now much easier to spot genuine imperfections in components and, as a result, reject rates have fallen".
The five-stage process begins with a one-minute immersion in oil-based penetrant dye.
Impellers then dwell for nine minutes over a drain tank to recoup excess dye and to allow capillary action to show up any defects.
Surplus penetrant is removed by a three-minute agitated water rinse.
This is followed by a heated water rinse that acts as a final wash while also serving to warm castings up prior to a ten-minute hot-air dry.
