If your business requires accurate foam parts, inserts or packaging, waterjet foam cutting can produce them in virtually any size, shape, or thickness.
Waterjet foam cutting uses a high-pressure stream of water to cut foam materials with exceptional precision. Unlike CNC routing, which uses a rotating cutter and leaves a radius in internal corners, waterjet cutting can create sharp corners, tight curves, and intricate shapes with a clean finish. The process is also particularly useful for producing narrow slots, deep cuts, and detailed profiles that would be difficult to achieve using traditional cutting tools. It is also possible to combine waterjet cutting with CNC routing to deliver the best solution for complex foam inserts and products.
At Polyformes, our multi-head waterjet cutting machines can process a wide range of foam materials and thicknesses. Our foam waterjet cutting service produces foam parts and products for many industries, including industrial, aerospace, defence, medical, and promotional sectors, where accuracy and consistency are essential.

The benefits of using waterjet cutting include:

Waterjet cutting is a process that uses a high-pressure stream of water to cut materials into specific shapes. For foam conversion, the waterjet follows a programmed cutting path to produce accurate parts with clean edges and intricate features.
Waterjet cutting is suitable for a wide range of foam materials, including polyethylene and other closed-cell foams. The process can accommodate a range of material densities and thicknesses, depending on the application.
Yes, waterjet cutting is often used alongside CNC routing and other foam conversion processes. Combining processes can often provide the most efficient and cost-effective solution for complex foam inserts, packaging, and specialist components.
Waterjet cutting can process a wide range of foam thicknesses. The maximum thickness depends on the foam grade, density, and required finish, but components up to 200mm thick can typically be manufactured.
