Needles in perforation rollers can be arranged in different patterns like linear pattern, crossed pattern and diamond pattern.
Micro perforation rollers are mainly use to perforate holes in papers or plastic films. Pin dia. up to 0.3 mm can be obtained to perforate micro holes.
Supporting Nylon or P.U. based rollers are manufactured at our company for perforating machineries.
Needle density up to 28 needles/ square cm can be obtained.
All of our rollers can be supplied as a single unit, or as a series of pattern-matching inter-locking units for lengthier applications.
Lengthy Rollers are often replaced at a very high cost, so we convert it into pinned segments that can be modified to fit any machine. The locating holes on each roller match precisely, so there are no interruptions in pattern and, by using this method, should only one roller be damaged in process, only that unit needs repair or replacement, rather than the complete unit .
Heat-treated and the best quality pins are used for hot perforation as well as cold perforation.
Rollers are made up of high graded G.M. or brass according to the material to be perforated.
With many years of experience in precision drilling, our highly skilled staff take pride in producing these quality parts with absolute accuracy.
