Industrial Grade Automatic Slitter Rewinder with ±0.03mm Precision for Paper Products

The ±0.03mm precision on this isn't just a number on a spec sheet—it's what actually makes those tight label rolls come out even, and we've seen it hold up consistently even after thousands of hours of running stickers and paper cup stock, usually around 20 days or so for delivery on standard orders.

Basically, the HC-320 uses a round knife system with a Delta inverter from Taiwan, and that gives you smoother acceleration than most comparable units in this weight class, though it's not ideal for anything with heavy adhesive backing because the blades gum up faster than you'd expect unless you swap them regularly, but for paper, labels, and bags, it handles about 100 meters per minute without wandering off the cut line.

What it does is handle a maximum unwinding width of 320mm and a rewinding roller diameter of 480mm, so if your matrial comes in at 300mm or so, you have some wiggle room, and teh photoelectric sensor for unwinding means the tension stays pretty tight even when the roll diameter changes mid-run.

The frame is heavy steel plate at 400kg total, which sounds like a lot but actually helps with vibration at higher speeds—those lighter aluminum machines tend to chatter above 80m/min, whereas this one stays solid, and the 0.75kW motor isn't massive but it's matched well for this size, just don't expect it to handle 500mm wide stock without a slowdown.

We usually have stock on the wooden pallet packaging, but if you need CE or TUV paperwork faster than standerd 12-month warranty period allows, give us a heads up because the cerification docs take about 2-4 weeks to process from the China factory, and the HS code is 84411000 for customs—most buyers go with the standard model without asking for custom blade angles.
