Advantages of rubber, resin, and pre-inked stamps

The stamp is a simple yet effective tool, used in many fields, including business, administration, at school, or even at home. It allows for the quick and clean reproduction of information, which offers numerous advantages.

It also plays an essential role in the organization and traceability of documents. In companies or administrative offices, it is often used to indicate the status of a file, which facilitates management and follow-up. It also helps to reduce human error by replacing manual writing with clear and precise marking.

From an administrative standpoint, a stamp holds official value. It can be used to authenticate a document or to prove that it has been processed by a competent authority.

Finally, in a more educational or personal context, stamps are also useful. At school, they allow teachers to provide quick and visual feedback to students using specific phrases. When designed to be fun, they can also motivate children.

We offer various stamp manufacturing technologies to meet the diverse requirements of our customers: rubber stamps, resin stamps, and pre-inked stamps.

The rubber stamp is particularly well-suited for intensive, professional use, thanks to its robustness and durability.
The resin stamp allows for extremely fine reproduction of details, making it ideal for complex visuals, precise logos, or fine typography.
The pre-inked stamp offers precision and clarity, even for very small characters, and is perfectly suited for commercial or administrative seals.

Thanks to this technological diversity, we are able to offer custom solutions tailored to various identification, marking, or communication needs.

We are a market leader and a renowned manufacturer of stamp-making machines. Our expertise and know-how allow us to support marking professionals throughout the entire production process, with reliable, high-performance solutions tailored to each technique.

How does the manufacture of rubber, resin, and pre-inked stamps work?

Here is a presentation of the manufacturing methodology for the three main types of stamps:

Rubber stamp

Creation of the negative film.
Exposure of the hard photopolymer through the negative.
Etching of the photopolymer.
Drying: removal of excess water.
Post-exposure: final hardening of the photopolymer.
Making an impression of the photopolymer in the matrix: obtaining a recessed mold.
Making an impression of the rubber in the matrix.
Cutting and mounting of the various stamps.

Resin stamp

Creation of the negative film.
Preparation of the resin.
Back exposure: base of the stamp.
Main exposure through the negative: characters.
Etching of the resin.
Post-exposure: final curing, removal of tackiness.
Drying: removal of excess water.
Cutting and assembly of the various stamps.

Pre-inked stamp

Production of the negative film.
Exposure of the hard photopolymer through the negative.
Etching of the photopolymer.
Drying: removal of excess water.
Post-exposure: final curing.
Impression of the photopolymer into the blank: obtaining a recessed matrix.
Securing the matrix in a steel frame.
Filling with premix, degassing, placement of the felt.
Gelation of the premix in the press.
Cooling of the frame.
Cold demolding, cutting, and assembly of the various stamps.

Pre-inked stamp with frame blank

Production of the negative film.
Exposure of the hard photopolymer through the negative.
Etching of the photopolymer.
Drying: removal of excess water.
Post-exposure: final hardening.
Impression of the photopolymer into the frame blank: obtaining a recessed matrix.
Filling with premix, degassing, and placement of the felt.
Gelation of the premix in the press.
Cooling of the frame blank, possible in open air.
Cold demolding, cutting, and assembly of the various stamps.
