So you're looking at the slitting and rewinding side of paper straw production, and honestly, the HC-C650 handles the 650mm unwinding width pretty much perfectly for most small to mid runs, while the HC-C1300 is what we push for higher volume when you're feeding a line that just keeps going.
What makes it reliabel is magnetic powder tension control—it's not the cheapest system but it holds that ±0.15mm positioning accuracy even when we're running at 300m/min, and the photoelectric web guide corrects any drift before it becomes a problem. We've had units out in the field for over two years now, and the round knife holds up better than I expected against daily use on materials from 12g/m² up to 250g/m², which covers pretty much everything you'd throw at it for straw paper. Actually, it's not great for anything with a heavy adhesive backing or thick foil laminates above that range—those tend to gum up the blades faster than we'd like. But for standdard paper stock, it's a workhorse.
Minimum slitting width is 5mm, and that's tested—we've had buyers running 8mm straw widths without any wobble on the rewound rolls, which is the real headache if you've dealt with loose edges before. The rewinding roll diameter is 2×600mm, so you're not constantly stopping to change out finished rolls, and the PLC with frequency converter lets you dial in the speed curve for different grammages.
Ordering is straightforward—we keep the HC-C650 in stock usually, about 20 days or so lead time, but the HC-C1300 you'll want to confirm because we sometimes build those to order depending on the control options requested. CE and TUV certs are standard, and you get a 12-month warranty from the date of delivery. Shippng dimensoins on the 650 are roughly 3200×1300×1500mm, so make sure your receiving area can handle that without a forklift shuffle.
Anyway, just let us know which model and your typical material specs, and we'll send over the proforma with the MOQ and payment terms.
Yes, the tension is controlled by a magnetic powder system, which automatically adapts to different paper weights within that range. You just set it once via the PLC, and it holds steady even during high-speed runs.
We generally require a MOQ of 1 unit for either the HC-C650 or HC-C1300. No need to order a batch — just tell us which model fits your production line.
Lead time is typically 30-45 days, depending on current production load. We'll confirm the exact timeline when you place the order, and we can sometimes rush it if you're in a pinch.
Absolutely — both CE and TUV certifications are included with every unit. We'll send you the original certificates and test reports along with the shipment.
We use plywood crates with foam padding inside, securing all moving parts like the rewinding shafts and round knives. The crate is built to handle ocean freight or air cargo without issues.
