We supply scraper blades for most makes of coating machines at competitive prices. Again as in the manufacture of our scraper cylinders, we have employed the same new technology, using only the highest quality alloys to produce a blade which will help to combat the abrasive qualities of BPA-ni White Titanium coatings. We offer wear resistant level : “Hard Wearing” .
Our blades are ground and honed in such a way as to last longer and bed in quicker. Our new blade grinding geometry greatly reduces the bedding in time and consequently extends the life of the scraper blades. Hitherto, the bedding in of scraper blades could take from 10 minutes to a couple of hours of lost production. The new process also has the facility to confirm (“in-house”) that the bedding in time of the finished blade is to within acceptable limits, thus by saving valuable coating and press production time. The system works so efficiently that our existing customers who normally grind their own scraper blades, now return all their blades for re-grinding.
Bedding in and Blade life
The bedding in time on our new blades is 1-15 minutes. The life of the blade (regardless of the supplier) is directly proportional to the evenness of the scraping edge. A “Cairncross” blade, which beds in quickly will by definition have a very even edge, promoting long life. Conversely a non Cairncross blade with an uneven edge will take a much longer time to remove the unevenness (high spots), thus by promoting short life.
Revolutionary Scraping (Compression) Rollers and Blades for all coating machines. (Designed for use with abrasive “White Titanium Coating”)
We supply new bottom scraper rollers for most makes of coating machines at up to 40% off manufacturers list price. Our new bottom scraper (compression) rollers, have been designed to help withstand the abrasion from white “Titanium” coatings. The new casting technology coupled with high-alloyed materials produces a fine grained hard-wearing structure, which is more resilient to abuse from over tensioned scraper blades! We offer these scraper rollers in two hardness levels: “Hard Wearing” & “Extra Hard Duty”.
"Hard Wearing" Scraper (Compression Roller)
The “Hard wearing” scraper roller is significantly harder than the “Standard” OEM (original equipment manufacturer) roller. This roller will therefore maintain its highly polished surface, which will enable it to perform longer at all levels, including white Titanium coatings. This roller has a much greater life span than the “Standard” OEM roller, we recommend that our “hard wearing scraper blade” be used with this roller.
“Extra Hard Duty” Scraper (Compression Roller)
The “Extra Hard Duty” scraper roller is significantly harder than our “hard wearing roller”. This roller is designed to maintain its highly polished surface “longer” in all conditions, including white Titanium coatings, and unintentional abuse from the machine operator, when the roller and blade is run dry. With this roller we recommend two blades : our “hard wearing blade”, or, our “extra hard duty” blade, both will give long life service, but the “extra hard duty” blade will last much longer.
The benefits of this cylinder and blades can be used to maximum effect when used in conjunction with our Pneumatic scraping system, typical wear from this cylinder using White Titanium would be 0.001" -0.002" per year, giving a life span of 10-15 years. OEM cylinders wear at 0.010"-0.015" per year on White Titanium and therefore have a life span of 2-3 years.
