Laser Cutting Films for keyboards

Foils for keyboards made of polycarbonate, polyester or polyimide

Plastic foils for keyboards

Modern laser technology is often used for cutting plastic film for membrane keyboards made from polycarbonate, polyimide, polyethylene terephthalate or polyester. To cut technical films with a laser, you need a laser cutter and – ideally – a vacuum table. The laser ensures that cut edges are melted in a controlled way. This produces perfectly-sealed cut edges. The process is gentle and doesn’t involve touching the material, meaning that chipping of the film ink is avoided.

Even the smallest shapes minimal radii can be produced without any issues. Benefit from perfect results at a manageable investment volume with a laser cutter from JustLaser! In comparison to alternative technologies like punching or cutting plotters, lasers are considered the quicker and more accurate process for day-to-day work.

WHICH FILMS CAN BE CUT WITH A LASER?

All kinds of film can be processed using a JustLaser Laser Cutter. Even metal foil with a thickness of up to 0.5 mm is no problem. Many companies use special plastic film for prototypes. Both front films and technical films can be processed using a laser. In practice, the following four types of plastic are usually used:

  • Polyethylene terephthalate
  • Polyester
  • Polycarbonate (maximum film thickness of about 0.2 mm, otherwise you get yellowed edges)
  • Polyimide

WHERE ARE FILMS CUT WITH A LASER USED?

It’s not only in prototyping that films cut using a laser are advantageous. Thanks to modern materials and optimised printing technology, there are a large number of applications today. There are also alternative types of cut, but many companies work with lasers due to the large number of benefits to the process. Anyone using a laser to cut technical films can rely on precise cut edges. At one time, lasers were only used for smaller numbers of units, but the use of a laser cutter is now considered the ideal cutting process for large quantities. The following film components are frequently cut using a laser:

  • Membrane keyboards
  • Back-injected films (automotive industry)
  • Front panels
  • Technical adhesive films (e.g. 3M or Tesa)
  • Multi-layer films (even with metallic interlayers, e.g. as a vapour barrier)

LASER CUTTING FILMS: PROCESS

Multi-layer films consisting of multiple layers such as adhesive, carrier and cover films, can be easily cut through completely in one step. Precise and clean cut edges are formed thanks to the targeted melting of the plastic. Even metallic layers are cut cleanly.

The laser cutters from JustLaser are based on modern control technology with axle drives precisely coordinated to each other. This means it is possible to cut even the finest patterns quickly and precisely. The films do not need to be clamped or secured to a vacuum table. They lie completely flat on the cutting table and are held in place by negative pressure. Lasers are often used in combination with a camera system. The cutting path also adjusts dynamically to flexible materials like flags or banners.

FUNCTIONS OF THE CO2 LASER CUTTER FROM JUSTLASER

Purchasing a relatively cost-effective CO2 laser cutter from JustLaser is the ideal solution for cutting technical films with a laser. It will win people over with its maximum flexibility, precise and dynamic axes and user-friendly laser software. Choose the table that best suits your specific film format from a large selection of table sizes. Vacuum tables ensure the plastic film is in the right place for laser cutting – without the need to fix anything in place mechanically.

Our technology offers economical automation functions, ensuring that the laser’s high throughput rate is utilised – and thus ensuring that the payback period is low. JustLaser Laser Cutters offer special camera recognition for working with printed plastic, ensuring precise and accurately contoured results.

WHAT ARE THE BENEFITS OF CUTTING TECHNICAL FILMS WITH A LASER?

It is not necessary to fix the material in place to cut technical films with a laser. The film is simply placed on the vacuum table and can then be processed immediately. While the force applied in punching often causes the material to peel, laser cutting produces clean and precise cuts. Post-processing is usually no longer necessary. Alternative methods often necessitate high maintenance costs (tool wear, etc.), but you can rely on cost-effective and consistently-high cutting quality with laser cutting. Laser cutting offers maximum flexibility when choosing the desired contours – without the need for annoying tool changes in between batches.
