Laser Engraving Delrin

What is Delrin?

Delrin is used for the production of embossing presses and pocket seals. Embossing presses are used by notaries, companies, engineers and government agencies to add relief embossings in addition to a signature, in order to protect quality documents from being copied fraudulently. Furthermore, an elegant embossing adds a personal touch to stationery and invitations. Whether it is a logo, home address or something creative: there is no limit to the number of possible applications when laser etching and laser engraving Delrin.

What is Delrin?

Delrin is a trade name for the material group polyacetal (POM). This material can be easily removed by a lser beam, making Delrin laser engraving a highly suitable process.
Laser cutting Delrin is also possible. 


Examples



Application examples for Delrin: Laser engraving

Delrin is used in the production of embossing presses and pocket seals. Embossing presses use a positive and a negative relief to emboss paper. The positive relief (male) is created with white letters on a black background and the negative relief (female) is inverted and mirrored. The Trotec JobCreator laser software can create the design of both reliefs automatically and therefore particularly easily. As laser cutting Delrin and laser engraving are both possible the presses can be completed using one machine.

Why should I buy a laser for Delrin laser cutting and engraving?

Trotec laser machines are a universal tool for material processing, as the beam negates the need for tool or grinding costs as with milling cutters or drills. During processing, such as mechanical engraving, materials must often be clamped in place or fixed with a vacuum. This is not necessary for laser engraving and laser cutting Delrin, saving time and money in production.

Tips for laser engraving Delrin

What requires special attention in the production of seal presses?

A good fit between the two forms is important. It is also necessary to ensure that the engraving has the correct depth. The engraving depth should be at least 0.25 mm, but a maximum depth of 0.50 mm must not be exceeded. If the engraving is too shallow, the embossing is barely visible. If the engraving is too deep, the paper may tear. Once determined, the parameters are stored in the materials database of the JobControl® software and can be retrieved at any time.

Which text size should be chosen for a perfect result?

Text or graphic elements must be at least 0.5 mm or no smaller than a five-point font size. When using significantly heavier paper grades such as 80 g/m², the size of the graphic components should also be increased.

How to prevent the press from cutting through the paper?

The problem with seal presses can be that Delrin often has sharp edges, and the punch thus cuts through the paper.

Our tip: Set the laser to be out of focus by around 2 mm (= Z-axis offset by 2 mm) and embossing results remain the same, but the edges are more rounded, thus making the process gentler to the paper.
