    Foam laser cutting with less waste and more design freedom

    Reduce material waste. Cut detailed geometries. Change designs without new tooling.

    Zenna Laser develops foam laser cutting systems that reduce material waste, cut small holes and complex contours, and switch designs without tooling. Request a cutting test.


    Foam cutting with less waste and more design freedom

    Foam is often expensive, while conventional die cutting leaves unused space between parts. Laser cutting uses a very narrow kerf and a digital cutting path. Parts can often be nested with less than 1 mm spacing, compared with around 3 mm for die cutting. The result is more products from the same sheet or roll.

    A laser can cut the outer contour and many small holes in one programmed process. Changing to another product design only requires a new cutting file—no new die.

    Key benefits

    • Less material waste — nesting spacing drops from ~3 mm (die) to under 1 mm where material and geometry allow.
    • Detailed cuts — small holes and outer contour in a single pass.
    • Fast design changes — switch geometries in software, no new dies needed.
    • Contactless processing — the laser cuts without compressing the foam.
    • Repeatable production — validated parameters are saved as recipes per material and product.


    Control of heat and edge colour

    Foam responds to heat differently depending on its composition, density, thickness and additives. Too much energy or insufficient extraction can affect the cut edge or cause discoloration.

    Zenna controls the process through laser power, cutting speed, focus and extraction. If required, the contour can be cut in several passes at lower power. This limits the thermal load while maintaining the required geometry.

    Send us your material, drawing and quality requirements. We test the complete product and show you the cut result before a machine concept is developed.


    Which foams can be laser cut?

    Suitability cannot be determined from the material name alone. Additives, coatings, adhesive layers and flame retardants can change the cutting result and emissions. Testing the actual material is therefore essential.

    ·      Polyurethane (PU) foam

    ·      Polyethylene (PE) and polyolefin foam

    ·      Polyester foam

    ·      EVA and other technical foams

    ·      Laminated or multilayer materials when every layer is laser-compatible


    Typical applications

    Packaging and inserts

    Tool inserts, case interiors and protective packaging with frequent design variants.

    Automotive and transport

    Seals, acoustic parts, insulation and interior components.

    Acoustic and thermal products

    Panels with small holes, ventilation patterns and outer contours.

    Gaskets and technical parts

    Products with internal openings, detailed geometry and controlled dimensions.

    Filters and porous materials

    Cut parts for filtration and ventilation, after validation of the cell structure and edge quality.

    Prototypes and series

    Test several geometries without tooling, then use the validated process for production.


    A system built around your product

    Zenna develops the complete production solution around your foam, product geometry, output and factory environment. Depending on the application, the system can include:

    ·      CO₂ laser source, optics and validated process recipes

    ·      Sheet, stack or roll handling

    ·      Vision for alignment and inspection

    ·      Automated loading, cutting, sorting and stacking

    ·      Extraction, filtration, fire detection and machine safety

    ·      Software connections to the production environment


    From sample to production

    1. Share the application

    Provide the material specification, Safety Data Sheet, thickness, drawing, volumes and quality criteria.

    2. Test the material

    Zenna cuts your product in its R&D Laser Cell and compares relevant process settings.

    3. Validate the result

    We assess cut quality, cycle time, thermal influence, emissions and repeatability.

    4. Engineer the system

    After validation, we define the laser, handling, automation, extraction, safety and controls.

    Frequently asked questions

    Can every foam be laser cut?

    No. Composition, additives and coatings determine suitability. Zenna checks the datasheet and tests the actual material.

    Can a laser cut small holes and the outside contour?

    Yes. Both can be included in one digital cutting program. The achievable size and speed depend on the foam and thickness.

    Does the laser discolor the foam?

    Heat can affect some foams. Zenna limits this through the correct balance of power, speed, focus and extraction, and can use multiple lower-power passes.

    How much material can be saved?

    The exact saving depends on part geometry and nesting. Where die cutting requires about 3 mm between parts, laser cutting can often reduce this to less than 1 mm.

    How quickly can a design be changed?

    A new cutting file replaces the existing geometry. No new die is required.

    Can Zenna test our finished product?

    Yes. We can test your foam and product geometry so you can evaluate the result before deciding on the production solution.
