Cutting soft materials like foam is hard. Try pushing in the blade of a knife and the material compresses. The thicker and softer the foam is, the more it deflects. The only way is to use the point of the knife: once the surface is pierced the blade can go through.
That's why we have a waterjet cutting machine. Like an incredibly sharp knife, it lets us cut complex profiles from soft materials up to 6" thick. If you need pieces for a flexible foam fabrication, talk to Merryweather about waterjet cutting.

Why cut with water?
It's a fast way of cutting out large, complicated shapes. It's a clean process with no chemicals or hazardous
- Pierce straight through so there's no need to cut in from the outside. Essential for creating contiguous shapes with hollow centers (as you'd need for a pocket.)
- Cuts very square, even on materials like thick reticulated polyurethane foam, and leaves smooth edges needing little to no finishing.
Verynarrow cut width or "kerf" thanks to the thin beam. This allows cutting of very intricate shapes and lets us nestshapes to use a sheet efficiently.
- No sideways forces, so there's no material distortion. This also lets us cut very thin wall sections.
- No heat, unlike laser cutting, so there's no unsightly edge melting or heat affected zone.
- There's no tooling or fixturing. All that's needed is a program for the waterjet's computer, and that comes from the CAD of the shape needed.
When is waterjet cutting appropriate?
With no need for
Small quantities that look good
Materials that are thick and soft, like those you might use in a custom foam fabrication, are difficult to cut cleanly. When appearance matters, tooling-free waterjet cutting is a cost-effective method of producing the shapes you need. If you're interested in learning more, contact us today.
