Applications

With a laser you can efficiently and quickly process rubber at little cost; whether you are producing an entire rubber plate or a single piece, you can significantly lessen production times with automated processes. That is why stamp engraving with laser devices has become the common method of choice in stamp production.  Furthermore, the laser is fitting 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 can produce a single piece or a series of productions in a cost-effective, flexible and efficient way.  Logos, photos, images or texts with precise details are no trouble for the system capabilities. With this laser system, you can take the layout straight from your graphics software to the material.  Additional support materials, such as matrices and films are no longer needed.  Features integrated into the JobControl® laser software, such as the automatic stamp making process, make stamp production simple and reduce your manufacturing process.

Function and advantages of laser technology

Profitable stamp production

  • Text plates are produced within a few minutes
  • No restriction on the number of stamps produced

Advantages of a Trotec laser

  • Speedy series: The fastest laser engravers available on the market with a maximum engraving speed of 3.55 m/sec and an acceleration of 5g.

Simple manufacturing

  • Designs are constructed in your usual graphics program and easily sent to the printer via the printer command
  • No specially trained operators are required

Advantages of a Trotec laser

  • JobControl® laser software: Work efficiently.  Simply intuitive.

No additional charges for the disposal of chemical waste products

  • No chemical additives similar to those used in other manufacturing processes (like when using photopolymers).

Advantages of a Trotec laser

  • The emerged particles and gases are simply eliminated and filtered out by the Trotec extraction systems.

Robust and durable

  • Unlike photopolymer production processes or vulcanization, there are no costs for additional support materials like matrices and films.
  • Material processing does not wear the laser beam

Advantages of a Trotec laser

Tips for engraving rubber

How to create a text plate with the laser?

When making the text plates for stamps, the design must be mirrored and inverted so that the imprint is legible. To achieve a detailed, clean impression on paper, it is vital to create so-called shoulders. The Trotec JobControl® laser software facilitates your stamp production by administering these processes in an automated way.  Thus, further processing is no longer needed.

How deep must the engraving be?

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

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

You can cut rubber into any shapes with the laser.  In the Trotec JobControl® laser software, various choices for automated laser cutting, such as square, round or optimized can be chosen.  In addition, the “Stege” [Webs] function facilitates the handling of entire plates.  The cutting lines are automatically interrupted at defined points, upon activation.  This facilitates the cleaning and removal of the plates.

Which lens is suitable for text plate production of stamps?

For images / texts 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 executes dust and oder.  It is important to provide an efficient extraction system for proper removal of the dust particles, equipped to filter the odors with a sufficient proportion of activated carbon .  It is also recommended to engrave the stamp plate from the top downwards, so the engraving quality is not affected by dust particles.

How can you incease productivity further?

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

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

After laser processing, it is best to place the plate briefly into an ultrasonic bath.  Another suitable alternative is detergent, water and a brush.
