50*9 White Sharp Blade Screen Printing Squeegee For Containers
Care And Maintenance To Extend Squeegee Life
Even the most solvent and abrasion resistant squeegees, such as our Duralife brand, can benefit from some preventive maintenance to maximize longevity.
1. STORAGE
a) Store in a dry and generally cool area (50–85 degrees Fahrenheit).
b) Do not store coiled; lie flat to avoid distorting the print edge.
2. MAINTENANCE/ROTATION For optimum squeegee life, rotate your blades in use as much as possible. All squeegees tend to swell and soften to some extent while in use. If they are given the opportunity to dry and return to their original state, they will last longer.
a) Establish a rotation schedule, based on the aggressiveness of your particular ink system, to allow the squeegee to “rest”.
b) Inspect for signs of swelling -- After approximately 2-4 hours of continuous printing with aggressive inks and solvents. After approximately 6-8 hours of continuous printing with moderate to weak inks and solvents.
c) Change the squeegee at the first sign of swelling. continued on next page 88 Visit our website at www.saati.com • email: Info.US@saatiprint.com
b) A blade-cut type sharpener, versus a belt or grinding wheel sharpener, will yield a print-ready squeegee after just one pass.
c) Belt or grinding wheel sharpening is acceptable for most applications. It is best done in a two-step process using multiple passes (and limited pressure) that take off as little material as possible. This reduces heat buildup, whichcan melt the squeegee.
STEP 1. Coarse grit (60-120) to remove worn edge.
STEP 2. Fine grit (160-300) to create a sharp edge and a smooth, polished finish. continued from previous page Duralife dual-durometer squeegees. Duralife color-coded squeegees. Duralife™ composite squeegees.
d) Before resting squeegee, clean thoroughly with a solvent to remove any ink residue.
e) Never soak any squeegee in a solvent for an extended period; irreversible damage could result.
f) Depending on the durometer, and the ink and solvent aggressiveness, the squeegee may require a minimum of 12 to 48 hours of rest before re-use or re-sharpening. (Softer duros tend to absorb more and require longer recovery.)
3. SHARPENING
a) Before sharpening, the squeegee may require a 12 to 48-hour rest (depending on ink and solvent aggressiveness) to allow any solvents to evaporate.
