Marking and engraving on prototype parts

Marking and engraving on prototype parts

The marking techniques are suitable for machined and vacuum casting prototype parts. Inscriptions can be added to the part using a small-radius milling cutter. They can be embossed or engraved.

Laser engraving

It is also possible to perform laser engraving marking on a prototype part. This inscription technique does not require the use of inks or sharp tools. This has an advantage over other marking techniques, as there are fewer manual manipulations.

In fact, it is not necessary to change the instruments or replace the ink. Laser marking is performed with a machine consisting of three parts: a laser, a control device and an area for placing the part. The laser touches the surface, heats it and evaporates the material. The route followed by the laser is computer-programmed. Our workshop can apply this finish to plastic and metal parts.

Screen printing and transfer printing

Screen printing is a printing technique used to transfer ink to a surface. An operator uses various instruments (paper, squeegee, etc.) to perform the process. Stencils may be used to prevent the transfer to certain areas. This technique is relevant to multicolored designs.


Example of screen printing in progress

Transfer printing: this method of printing uses a machine to exert pressure with high heat or water. The advantage of this technique is the quality of adhesion of the design and its weather resistance.


In this technique, the marking on the surface of a part is made by transferring ink.
