Cold-Knife Cutting for Hypalon and Marine Fabrics
Hypalon, Neoprene and PVC-coated boat fabrics need a cold cut. MNT digital oscillating-knife cutters slice them straight from your file with no die and no laser heat.
Because the blade never burns the material, the cut edge keeps its original bonding surface — critical for the glued and heat-welded seams that hold an inflatable boat together. See the full MNT digital cutting machine range.
Marine & Inflatable Fabrics We Cut
Hypalon (CSM)
A chlorosulfonated-polyethylene coated fabric — UV, saltwater and chemical proof. Cut cold so the coating and seam stay bondable.
Neoprene
Chloroprene rubber for wetsuits, gaskets and padding. The knife keeps a clean, flexible edge with no melt or hardening.
Hypalon-Neoprene Composite
The boat and RIB standard — Hypalon outer over a neoprene inner. Cold cutting protects both layers so panels glue and weld cleanly.
PVC-Coated Fabric & Tarpaulin
Banners, covers, tents and tarps cut and marked in one pass, with clean edges ready for RF or hot-air welding.
What You Can Build
RIB & Inflatable Boats
Tubes, baffles and patches cut cold for airtight, bonded seams — the edge still takes glue and heat-weld.
Military & Rescue Craft
Heavy-duty Hypalon parts cut and marked for fast, repeatable assembly of professional RIBs.
Drysuits & Wetsuits
Neoprene panels cut clean with no melted edge, ready for blind-stitch and glue.
Waterproof Bags & Floats
Welded and glued dry bags, buoyancy tubes and containment bags need un-charred edges.
Tarpaulin & Marine Covers
PVC-coated tarps, biminis and boat covers cut to shape with weld-ready edges.
Inflatable Structures
Tents, buoys and inflatable structures from PVC and Hypalon, cut straight from your CAD file.

Why Cold-Knife Cutting Wins for Bonded Marine Fabric
Hypalon and neoprene both contain chlorine. Laser-cutting them chars the edge and releases hydrogen-chloride fumes — and that hard, carbonized rim is exactly where a glued or welded seam fails.
| Factor | CO₂ Laser | Digital Knife (cold) |
|---|---|---|
| Bonded / welded seam | Charred edge, seam fails | Edge stays bondable |
| Fumes | Chlorine / HCl gas | None |
| Edge | Hardened, yellowed | Clean, flexible |
| Fine detail / small text | Excellent | Good |
| Speed on thick composite | Slow, more burn | Fast |
Professional inflatable builders even buff the Hypalon surface before bonding — a laser-hardened edge defeats that entirely. Use the laser only for non-bonded decorative cuts and fine text; cut every bonded part cold.

Frequently Asked Questions
Can you laser cut Hypalon?
You can, but the beam chars the edge and releases hydrogen-chloride fumes, and the hardened rim ruins glued or heat-welded seams. For any bonded marine part, a cold knife is the safer choice; save the laser for non-bonded decorative cuts.
Does cutting affect the bond or weld seam?
With a knife, no — cold cutting keeps the fabric’s original bonding surface right to the edge. Laser cutting carbonizes the edge, which is the most common cause of seam failure on inflatable boats.
What marine materials can it cut?
Hypalon (CSM), Neoprene, Hypalon-Neoprene composite, PVC-coated boat fabric and tarpaulin — from thin coated cloth up to thick rubber composite, all from one machine.
How thick a fabric can it cut?
From thin PVC-coated cloth to roughly 8–10 mm rubber composite, cut with a square, bondable edge. Send a sample and we confirm the exact setup.
Do I need a die?
No. Parts cut straight from your CAD file with no die — no tooling cost and same-day design changes, ideal for prototypes and short marine runs.
How much does a Hypalon cutting machine cost?
Price depends on working size and tool set; there is no per-shape die cost. Send your material, size and volume and we quote within 24 hours.
Hypalon & Marine Cutting — Technical Guides
Cutting Hypalon and marine fabrics raises real questions — whether a laser can be used, how to keep seams bondable, and which tool suits coated rubber. Our guides walk through cold-knife cutting so your glued and welded seams hold.
