SEAL MANUFACTURER ELIMINATES TRICH
Thorough degreasing ensures effective bonding for aerospace and automotive seals
 A Microsolve system enabled seal manufacturer Wills Engineered Polymers to remove the potentially harmful solvent trichloroethylene (trich, trike, or TCE) from its cleaning process. Wills installed a Kerry Microsolve 350 mono-solvent ultrasonic cleaning system to rid metal seals destined for the aerospace and automotive industries of sand, oil and grease. The Microsolve unit uses the solvent Lenium ES and replaced a solvent degreaser that ran on trike.
The seals range from 1cm - 20cm in diameter and must be thoroughly degreased to ensure that rubber bonds effectively to them. Poor bonding would result in the seals failing once in use.
The PLC-controlled cleaning process comprises ultrasonic cleaning followed by a vapour rinse and then a freeboard dry. The vapour is essential to both the rinsing and drying processes, as well as to the distillation cycle. Distilled solvent, condensed by the primary cooling coils, passes through a water separator with in-line heat exchanger and returns to the ultrasonic tank, displacing contaminated solvent into the boiling sump. Along with filtration of the solvent, distillation ensures that the ultrasonic tank is maintained at a controlled level of cleanliness.
The machine also features the Microsolve solvent monitoring and auto top-up system to ensure low solvent consumption, along with an Autotrans Mk 4 automatic handling transporter for consistent results and high throughput.
