Tips to drill better quality holes on laminated prints and plastic sheets
On a post a week ago, we introduced how we produce drill bits at high level of precision and that we keep trying hard to catch up customers’ requests.
Today, as customers requests more “added-value” prints, we are getting more requests from printers for solutions to punch holes on various materials with different coatings. So the paper drills nowadays are used not only for papers, but also for plastic films, labels, synthetic sheets, lenticular sheets and so on. Swing tags are the one of the typical applications that we are often asked for solutions. As written before, more printers are aware that tags on-demand is a good business and a paper drill is an essential part.
Generally, valuable prints requires higher quality. On the contrary, it is more difficult to finish such materials with high precision and less damage. For example, when punching on laminated sheets, strokes need to be not too long but not too short. Short strokes cause burrs on surfaces of sheets and laminating films peeled away from the sheets. Long strokes cause generating frictional heat, ending up with sheets stuck on each other.
To avoid such troubles, we offer “Teflon-coated” drill bits. Teflon coating enhances the durability and smoothness of drill bits, helps drill bits punch holes with better quality especially on laminated sheets and labels. Especially if you are using a high-end paper drill, which is capable to change the rotating speed of spindle, difference is significant when run at slower speed.
Thus, drill bits seem to be small pieces of metal but the high quality ones are actually made with full of technologies. There are lots of techniques behind how they are made, and of course there are some tips to use them properly.
Mr. Tsubakihara, the director of Sakura Seiki gave us an advice. “For longer lifetime of drill bits, we suggest to take the drill bits off the machine and to remove paper chips inside after use. If the chips are left inside the drill bits, they absorb humidity and cause the rust. Moisten chips also swell in the drill bits, and cause the chips clogging up when they are used the next time. Please also ensure to resharpen drill bits when they are being dull. These can damage and shorten lifetimes of the drill bits. As long as they are maintained properly, our drill bits keep quality at very high level and last long.”
