Laser engraving delrin

for the production of embossing presses

What is Delrin?

Delrin is used for the production of embossing presses. Embossing presses are utilized by notaries, companies, engineers and government agencies to add relief embossings, additionally to a signature, so as to shield quality documents from being derived fraudulently. moreover, a sublime embossing adds a personal touch to stationery and invitations. whether it is a emblem, home address or something artistic, there is no limit to the quantity of attainable applications.

What is Delrin?

Delrin is a trade name for the material group polyacetal (POM). This material is highly suitable for laser etching, laser cutting or engraving because it can easily be removed by the laser beam.  


Application examples for Delrin

Delrin is used in the production of embossing presses. 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.

Why should I buy a laser for engraving Delrin?

The laser beam is a universal tool for material processing, thus there is no need for tool or grinding costs for milling cutters or drills. throughout processes similar to mechanical engraving, materials should typically be clamped in place or fastened with a vacuum. this is often not necessary in laser processing, that saves time and money.

Tips for engraving Delrin

What requires special attention in the manufacturing of seal presses?

A good fit between the two forms is important. It is conjointly necessary to make sure that the engraving has the proper depth. The engraving depth ought to be a minimum of 0.25 mm, however a maximum depth of 0.50 mm should not be exceeded. If the engraving is too shallow, the embossing is barely visible. If the engraving is too deep, the paper might tear. Once determined, the parameters are stored within the materials database of the JobControl® software system and can be retrieved at any time.

Which text size should be chosen for a perfect result?

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

How do you prevent the press from cutting through the paper?

The problem with seal presses can be that Delrin often has too sharp edges, and the punch therefore cuts right through the paper. Top tip: Set the laser to be out of focus by around 2 mm (= Z-axis offset by 2 mm) – embossing results remain the same, but the edges become more rounded, and the process is therefore gentler to the paper.
