Automation engineer / Poly-technician / Equipment manufacturer

Each year, our company takes on one automation engineer apprentice, and every second year one poly-technician and equipment manufacturing apprentice each.

Duration of apprenticeship

The apprenticeship lasts four years.

Vocational school

The apprentice will spend a maximum of 2 days per week at the vocational school in Interlaken (automation engineer) , Bern (poly-technician) or in Thun (equipment manufacturer).

Internal training

During his vocational apprenticeship, each apprentice spends at least one training period in one of the following departments:

  • Mechanics
  • Electro-technique
  • Assembly
  • Construction
  • Locksmith’s shop

This ensures that a very extensive field of knowledge is covered.

WElcome To the wide world of screen printing

The screen printing method – also called the fourth printing process – is often underestimated.

Many users and customers simply have no idea how many products used in their everyday life are in some way connected to screen printing! This printing method is applied by more than 50 industrial sectors, and its objective is always focused on function or decoration, or even both combined.

Screen printing is used in countless market segments, and as a consequence the requirements to be met by the individual screens vary from one application to another. Today, the printers handle everything, from the smallest screen formats up to extremely large ones (4.8 x 12 m).



Decoration and finishing in textile printing

labels textilThe term textile printing refers to printing procedures used for printing textiles, a process which is considerably more complex than paper printing, as the various print supports (cotton, polyester, silk, etc.) require particular inks and forms of treatment.




Function and decoration in industrial printing

labels industrieIn the industrial sector, screen printing deploys its particular strengths where flexibility and application possibilities are a prime consideration. A growing number of industrial sectors resort to this printing method, which optimally answers their needs with regard to functionality and/or decoration.

The virtually limitless choice of materials that can be printed turns screen printing into a unique and unequaled method.




Decoration and varnishing in the graphic sector

labels textilNow as before, screen printing plays a major role for graphical applications. This is the printing method par excellence for all the application cases where highest requirements need to be met in terms of consistency, handling of various formats, material selection and rapidity.

Differentiation and added value thanks to screen printing!
