Engraving rubber with a laser

Rubber engraving for stamp making

Rubber engraving for stamp making

The laser can be used to engrave texts in the smallest fonts, logos with fine details or even pictures directly into the rubber. With a Trotec laser system, you can create stamps in an efficient, inexpensive, simple and environmentally-friendly way with the highest precision to produce clean, detailed, quality imprints without chemicals.

Rubber types suitable for laser engraving

  • Laser rubber
  • Natural rubber
  • Synthetic rubber
  • Microporous laser foam
  • Oil resistant laser rubber

Applications

With a laser you can quickly and efficiently process rubber at little cost; whether you are producing a single piece or an entire rubber plate, you can significantly reduce production times with automated processes. That is why stamp engraving with laser devices has become the standard method of choice in stamp production. Furthermore, the laser is suitable for producing laser-engraved printing forms made of rubber for flexographic printing.

Why should I buy a laser for rubber engraving?

With a Trotec laser system, you will be able to produce series productions and single peices in an efficient, cost-effective and flexible manner. Texts, logos, photos or images with fine details are no problem for the system capabilities. With this laser system, you can take the layout directly from your graphics software to the material. Additional support materials, such as films and matrices are no longer necessary. Features integrated into the JobControl® laser software, such as the automatic stamp making process, make stamp production very easy and shorten your manufacturing process.

Tips for engraving rubber

How to create a text plate with the laser?

When creating the text plates for stamps, the design must be inverted and mirrored so that the impression is readable. To obtain a clean, detailed impression on paper, it is important to create so-called shoulders. The Trotec JobControl® laser software facilitates your stamp production by executing these processes in an automated fashion. Further processing is thus no longer required.

How deep must the engraving be?

The engraving depth of stamps should be about 0.9 – 1.1 mm. With the JobControl® materials database, the optimal laser parameters for Trotec materials are included in the scope of delivery.

Can (rubber stamps) be cut with the laser as well?

Rubber can be cut to any shape with the laser. In the Trotec JobControl® laser software, various options for automated laser cutting, such as round, square or optimized, can be selected. In addition, the “Stege” [Webs] function facilitates the handling of entire plates. Upon activation, the cutting lines are automatically interrupted at defined points. This facilitates the removal and cleaning of the plates.

Which lens is suitable for text plate production of stamps?

For texts / images with delicate details, we recommend using the 1.5” lens.

What must be taken into account in the processing of rubber with the laser?

The processing of rubber stamps releases odor and dust. It is therefore important to provide an efficient extraction system for good removal of the dust particles, equipped with a sufficient proportion of activated carbon to filter the odors. We also recommend engraving the stamp plate from the top downwards, so the engraving quality is not affected by dust particles.

How can productivity be increased even further?

Laser engraving of rubber requires relatively high power output to achieve a certain level of productivity. The more power is used, the faster the engraving.

How to clean a laser-engraved and -cut text plate?

It is best to place the plate briefly into an ultrasonic bath after laser processing. Alternatively, water, detergent and a brush are also suitable.
